From personalized gifts to retail gift sets, custom tins enhance every aspect of the tea drinking experience.

How do tea tins extend their shelf life by blocking moisture and light?

May 14, 2025/in News /by admin

Tea leaves are highly hygroscopic, easily absorbing moisture and odors, leading to mold growth, flavor loss, and a shortened shelf life. In addition, exposure to light, especially ultraviolet light, causes chlorophyll to decompose and essential oils to oxidize, making the tea taste deteriorated and bland. Therefore, we must effectively protect tea tins from moisture and light through high-quality tea tins to ensure that tea lovers can enjoy fresh tea leaves for a long time after purchasing them. By selecting high-quality moisture-proof materials in tea tins, adding seals and gaskets can indicate the sealing performance of tea tins.

Choosing high-quality moisture-proof materials for tea tins?

Tea We use food-grade tinplate, a steel plate coated with a layer of pure tin, with inherent moisture and corrosion resistance. At the same time, manufacturers coat the inside of the tinplate with FDA-approved epoxy resin or polymer paint to form a sealed structure that prevents water vapor penetration. This multi-layer structure keeps the water vapor transmission rate below 0.1 grams per square meter daily, which is better than plastic or paper packaging. These coatings also prevent metal from penetrating the tea leaves, ensuring the safety and flavor of the tea. By choosing this material, the tea tin cans can effectively protect the tea leaves from fluctuations in ambient humidity, keeping them crisp throughout their shelf life and preventing caking or microbial spoilage, even under changing climatic conditions.

Adding seals and gaskets to tea tins

Even the best tea tins must address potential infiltration points, primarily at the lid joint. During the production of tea tins, manufacturers use precision-engineered lids with double-lip crimp seals and optional food-grade silicone gaskets. The double-lip design ensures the lid presses evenly onto the tin, forming an airtight, moisture-proof interface. We offer heat-sealed inner foil liners for some special customer requirements to further isolate the tea leaves from external moisture and oxygen. At the same time, drop tests and vacuum decay measurements confirm that these tea tins maintain internal humidity levels below 2% relative humidity (RH). By preventing moisture exchange, these sealing innovations keep the tea leaves fresh, aromatic, and protected from adverse environmental influences, making tea tins ideal for high-end tea brands and the gift market.

Designed for light blocking and UV protection

Light, especially UV and visible light, accelerates the oxidative decomposition of polyphenols and volatile aromatic compounds in tea leaves. Tsing’s tea caddies feature highly reflective opaque metal walls. Both matte paint and polished metal reflect incident light in the exterior finish, while the tinplate itself is 100% opaque. For additional protection, we also integrate UV-absorbing inks and clear coatings that block up to 98% of harmful UV rays, as certified by spectrophotometric analysis. This layered approach ensures that the tea tin cans not only prevent photodegradation, but also maintain consistent internal light levels, thereby protecting the color, flavor and nutritional properties of tea leaves during long-term storage from retail shelves to home pantries.

Desiccant integration and lining

To further control internal humidity, Tsing’s tea tins can be equipped with custom desiccant packs or bags to absorb residual water vapor. Tsing places these food-safe desiccants in a ventilated inner tray to prevent them from coming into direct contact with the tea leaves while maximizing their moisture absorption capacity. In addition, a removable PET liner provides a second barrier, making it easy to clean and reuse the tea tin. By integrating desiccant and liner, the combined system maintains an ultra-dry environment, ensuring that volatile aroma compounds are locked in the tea, providing a consistent, high-quality sensory experience. This modular design supports both bulk commercial storage and manual retail packaging.

Structural design for enhanced protection

In addition to the material and seal, the physical design of the tea tin also plays a vital role in protecting against moisture and light. Precision manufacturing processes create tea tins with a gap as small as 0.2 mm between the tin body and the tin lid, minimizing the penetration of the external environment. The seams are double-folded and laser-welded for uniform strength to prevent micro-cracks that may affect barrier properties. For the storage of loose tea, we offer square or rectangular tea tins with reinforced corners and ribbed edges to enhance the rigidity of the tea and reduce the risk of deformation during stacking and transportation. These design features ensure that the tea tins maintain their protective properties under actual transportation conditions, protecting them from the factory to the final drinking process.

Maximize tea freshness

From food-grade tinplate substrates and polymer lacquers to sealing gaskets, UV-resistant coatings and desiccant integration, every element of tea tin can design is critical to ensure that tea quality does not deteriorate. By adopting these comprehensive barrier packaging solutions, we enable tea brands to ensure that their products maintain optimal flavor, aroma and nutritional value, thereby improving consumer satisfaction and enhancing brand trust.

How do metal tin box solve the problem of extrusion damage in biscuit packaging?

May 12, 2025/in News /by admin

For biscuit manufacturers, crush damage is one of the most common problems in the entire transportation process from the factory to the consumer. The fragile biscuits will crack, break, or deform due to pressure during stacking, transportation, and handling. Unlike cardboard or plastic containers, high-quality metal tin box have excellent structural support and rigidity, effectively dispersing external loads and reducing local stress. As a metal can manufacturer, Tsing will provide information on how metal tin box solutions can eliminate crush damage and keep biscuits fresh from the manufacturer’s perspective.

Material Strength and Structural Integrity of a metal tin box

Tsing chooses tinplate as the material to protect biscuits from damage caused by crushing forces, which has excellent stiffness and deformation resistance. With a yield strength of more than 200 MPa, its structural stiffness is unmatched by other materials. To further enhance durability, the metal tin box uses pressed ribs and gussets, which act as integral support beams to prevent the panel from bulging under vertical pressure. This rib structure enhances load-bearing capacity and improves resistance to side impact during handling.

At the same time, all tinplate surfaces are treated with a proprietary anti-corrosion passivation treatment to ensure that the metal tin boxes can effectively resist moisture and avoid humid environments that cause structural damage due to long-term use. The combination of these materials and structures can withstand heavy stacking in warehouses and bumps during transportation while maintaining the original state of the biscuits inside.

Increase internal cushioning to reduce impact.

Even the sturdiest metal tin boxes cannot prevent damage from sudden impact or falls without internal protection. Tsing’s tin can engineers solved this problem by designing an interlocking box lid and box bottom structure with a tolerance of only ±0.2 mm to ensure the box remains square under dynamic conditions. We incorporate high-performance cushioning pads, custom-molded to the exact dimensions of each biscuit, within these precision-fitted metal tin box shells. These pads gently support the biscuits, maintain consistent inter-layer spacing, and absorb kinetic energy during impact.

For fragile sandwich or cream sandwich biscuits, we provide a layered tray design with independent compartments to prevent lateral movement that may cause the biscuits to crack. Ensure the cookies remain intact after repeated drop tests or simulated handling over rough terrain.

Sealing and moisture resistance

To ensure that the metal tin box maintain the flavor of the cookies, we also ensure humidity control throughout the can when designing. Precision-engineered double-lip seals and food-grade elastomeric gaskets are used in metal tin box solutions to achieve a barrier equivalent to IPX4 against moisture and airborne contaminants. This airtight seal prevents moisture intrusion, preventing the cookies from softening and making them more susceptible to crush damage. In addition, the non-porous tinplate substrate resists water vapor diffusion, further maintaining internal closure. For high-humidity markets such as Southeast Asian or South American climates, our metal tin designs include desiccant compartments or optional vacuum sealing processes to maintain an optimal low-humidity environment. This allows manufacturers to extend shelf life and reduce transportation damage claims significantly.

Enable customizable metal tin box shapes and stackable designs.

Versatile metal tin box geometry also plays a vital role in retail display. Tsing’s broad portfolio includes rectangular, square, cylindrical, and custom polygonal tins designed to maximize stacking strength and minimize wasted pallet space. Reinforcement features such as beads and gussets allow high stacking configurations up to 10 layers. Different custom tin shapes cater to specific biscuit formats, from slim rectangular tins for long fingers or wafer sticks, square tins for assorted biscuits, to round tins for cookies or seasonal shapes. These options allow brands to maintain a consistent packaging footprint across product lines, resulting in a coordinated supply chain.

Aesthetics meets practical protection.

Packaging must also be functional and visually superior in the premium biscuit market. Tsing’s metal tin manufacturing process incorporates advanced decoration technologies, including digital offset printing for full-pack high-resolution graphics, precision embossing for tactile logos, and hot stamping for metal foil without compromising barrier properties. Gloss, matte, or special soft-touch finishes can be added to our in-house coating lines to prevent sagging or uneven curing. These decorative layers adhere seamlessly to the tinplate, maintaining the metal tin box’s structural strength and moisture resistance. European and North American brands will use this combination of form and function to create a metal tin box worth giving away, which can become a souvenir for future use.

Ensure damage-free, high-quality biscuit packaging.

Tsing metal tin box solutions cover high-strength tinplate materials, precision sealing, internal buffering, stackable design, and customizable design to ensure that the biscuits are intact and our customers can deliver them perfectly to consumers. With metal tin packaging, biscuit brands can significantly reduce breakage rates, provide solid protection and exquisite appearance, and enhance market positioning.

German candle brands Top criteria for buying quality candle tins

May 9, 2025/in News /by admin

German candle brands have exquisite candle craftsmanship. Therefore, when they choose candle tins, they emphasize not only a container for scented candles but also a concrete embodiment of brand value, aesthetics, and performance. German manufacturers evaluate their containers with strict standards to ensure that each candle tin meets high durability, safety, and fashion standards.

In this article, we will share from the perspective of candle tin manufacturers the top criteria that German candle brands follow when choosing candle tins. We will share from the perspective of material composition, thermal properties, decorative surface treatment, lid and sealing functions, and understand how these factors reflect Germany’s exquisite craftsmanship.

Material selection and thermal conductivity of candle tins

For German candle brands that focus on safety and performance, the choice of base metal directly affects the consistency of candle melting and burning. Candle tins made of high-grade aluminum have excellent thermal conductivity (about 205 W/m·K), which helps to form a uniform melt pool and reduce tunneling. Tinplate is a durable, cost-effective alternative with corrosion resistance while maintaining good heat distribution, especially when paired with an anodized or primed interior.

In addition to conductivity, our candle jars undergo rigorous material testing to ensure food-grade compliance and high temperature resistance. Candle tin manufacturers often require repeated burn tests on prototype samples to measure changes in tin wall temperature and verify that they do not deform under continuous heating. This meticulous testing method ensures that each candle jar provides optimal fragrance distribution, stable burning rate, and safe operation.

Requirements for durability, surface treatment, and aesthetics of candle tins

German candle brands do not compromise the candle tins’ visual and tactile quality. Therefore, the durability of candle tin cans is evaluated through scratch resistance tests, drop simulations, and wear tests on the selected surface coatings, including high-gloss paint, matte soft-touch coatings, or metal powder coatings. High-quality surface coatings prevent wear and tear during transportation and handling and complement the candle’s iconic fragrance to form a unified brand image. Decorative techniques play a central role in the choice of candle jars: precision screen printing, all-inclusive digital graphics, and custom embossing. German manufacturers often request spot UV or foil decoration to highlight limited edition collections, reinforcing the value proposition of decorated candle jars.

Heat distribution and burning performance

Well-designed candle tins optimize heat transfer to the wax pool, promoting complete melting of the candle from edge to edge, thereby maximizing fragrance release. When sourcing, German candle brands often ask about the candle tin’s wall thickness and bottom geometry to disperse heat inwards and prevent cold spots at the edges.

In addition, as candle tin manufacturers, we also test the ability of candle jars to dissipate residual heat after the flame is extinguished; well-designed candle tins cool evenly, extending the candle’s life and protecting the artwork. By conducting these rigorous tests in a dedicated burning laboratory, German candle brands can be assured that the quality candle jars provide continuous fragrance and maintain a safe temperature range.

Lid design, seal integrity, and safety

A strong lid design is one of the components of a high-quality candle tin, especially for products that are easy to carry or as gifts. German candle brands carefully check the fit tolerances of lids, striving for a precise gap of 0.1 to 0.2 mm to prevent wax scent leakage while still allowing easy opening. Some brands integrate silicone gaskets or threaded lids into candle tins to achieve an airtight seal, extend scent longevity, and prevent contamination.

Safety is also critical: round candle tins with lids must resist heat deformation and be securely fastened to prevent accidental detachment. Brands often perform drop tests on fully charred tins to confirm that lids are secure under impact. In the aromatherapy product range, sealed candle jars also maintain the integrity of terpenes, ensuring that therapeutic aromas remain potent.

Sustainability and eco-conscious practices

Most German candle brands have an environmentally friendly mindset when choosing candle tins that fit their green philosophy. Recyclable materials such as food-grade tinplate and environmentally friendly coatings with water-based or UV-curing formulas can reduce carbon footprint and VOC emissions. Often, these brands require suppliers to conduct a life cycle assessment (LCA) to verify the overall environmental impact of the candle tin from raw material sourcing to end-of-life recycling.

Tsing now uses recyclable materials in candle tins without sacrificing performance and aesthetics. In addition, brands have prioritized reducing packaging weight, thinner metal thickness, and optimized lid design to reduce transportation emissions. By adopting these sustainable candle tins, German candle manufacturers can meet their demand for environmentally friendly products.

Custom Printing Tips for Custom Tin Cans for Promotional Events

May 7, 2025/in News /by admin

The first step in choosing a custom tin can for your promotion is identifying your goals. Is your goal to increase brand awareness with custom tin packaging at a trade show or to increase booth traffic with free giveaways? Knowing the end purpose of your promotional custom tin can, Tsing will guide you through every decision, from size and shape to printing range and budget allocation. For full packaging and custom tin cans targeting young people, you can use eye-catching graphics that resonate. For some high-end venues, elegant and simple designs, such as foil or embossed logos on matte custom tins, are required. It’s also necessary to consider the canned product: mint cans, cosmetic samples, or snack-sized snacks require different tin shapes and printing surfaces.

Design eye-catching graphics and brand logos for custom tin cans.

Tin cans have limited curved surfaces and require careful layout to ensure clarity and visual impact from all viewing angles. Start with your core brand elements (logo, fonts, and signature colors) and build around them to create a unified visual hierarchy that guides the eye.

When designing custom tins, we prioritize legibility. Incorporate a visual focal point in the front panel, such as a central logo or key tagline, and keep secondary details in the back or side panels. For 360° designs, ensure seamless wraparound coverage: extend the background beyond the bleed line and use vector artwork to prevent pixelation. Of course, custom tins used for promotional events often sit on a desk or kitchen counter long after the event. You can subtly incorporate a QR code or NFC tag into the design to encourage interaction after the event.

Choosing the right printing technology for custom tin cans

Standard printing technologies include offset, digital UV printing, and screen printing, each with advantages based on print volume, color complexity, and special effects. Offset excels at high-volume printing (5,000+ pieces), providing consistent full-color coverage and fine detail at a competitive unit cost. It handles Pantone spot inks, metallics, and varnishes well.

Digital UV printing, on the other hand, offers the flexibility to print in small batches (3,000 cans) without the cost of printing plates, allowing for rapid design iterations. Its ability to print directly onto curved surfaces with minimal setup is ideal for temporary custom promotional cans. Screen printing is perfect for high opacity or metallic ink applications, such as printing a white base on a dark candle tin or using glitter foil. Although single-pass printing has limited colors, it can create rich textures.

Manage Color Accuracy and Pantone Matching

Color fidelity is critical when producing custom tins. Tsing utilizes spot color inks from PMS to achieve consistent results across print runs. Metallic or coated cans can change color perception, so we provide mock-ups on the tin body to ensure that the inks appear under event lighting. For gradients or photographic elements, we ensure that the CMYK profile is optimized for UV or offset printing and check for banding issues on curved surfaces. Calibration proofs help identify potential color mismatches before the official printing. Consistent ink layering and UV curing time are essential to prevent color drift. By implementing strict color accuracy protocols, you can ensure your custom tins will enhance brand integrity and stand out in any promotional environment.

Impact of Materials and Surface Treatments on Print Quality

A custom tin’s substrate and surface treatment can affect aesthetics and print quality. Standard materials include tinplate and aluminum, each with different printing suitability and durability. Tinplate is widely used because it is rigid and easy to decorate.

Optional surface treatments include gloss, matte, soft touch, textured, or metallic. Glossy finishes enhance color vibrancy and protect against wear, while matte or soft touch coatings provide a premium tactile feel suitable for products in high-end event venues. Textured patterns add depth and grip, but designers may need to adjust the artwork to prevent ink from accumulating in the grooves. You must choose the material and surface treatment based on your product and its intended use scenario. The choice of material, surface treatment, and printing technology will directly affect the life and shelf appeal of your promotional custom tin can.

Logistics and cost optimization

When you plan large-scale custom tin can production, you should negotiate the lead time covering printing and assembly, typically 4–6 weeks for offset printing and 2–3 weeks for digital printing. Consolidate shipping to reduce freight costs, and consider warehousing solutions to ensure timely campaign distribution. Bulk pricing can significantly reduce unit costs, and locking in quantity ranges such as 5,000, 10,000, 20,000 cans, etc., can help your suppliers optimize material procurement and printing schedules. Where feasible, standardize can sizes across multiple campaigns to simplify tooling and minimize conversion costs. By proactively coordinating logistics and leveraging cost optimization strategies, you can ensure that custom tin cans for promotional campaigns arrive on time and within budget, attracting audiences and driving brand engagement.

Ultimately

Creating outstanding custom tin cans for promotional campaigns requires a holistic approach: from identifying campaign goals and designing engaging graphics to selecting the right printing technology, materials, and finishes. You can ensure brand consistency and consumer satisfaction by managing color accuracy, thorough prototyping, and strict quality control. Finally, a sound logistics and cost strategy ensures that your campaigns are completed on time and within budget.

How can you design a candle tin to ensure heat distribution for an even burn?

May 2, 2025/in News /by admin

Making candle tins burn evenly and cleanly starts with careful design to ensure even heat distribution across the wax surface. Uneven heat can lead to tunneling—the wax melts from the center while the edges remain solid, which wastes wax and shortens the overall burn time. To avoid this, designers at Tsing consider every aspect of the candle jar: the thermal conductivity of the material, wall thickness, aspect ratio, ventilation, and even the shape of the base. Even the burning behavior of a candle can be strongly affected by environmental conditions, such as room temperature or air circulation, so the design of the tin container is critical. This article will explore seven key design elements of candle tin construction to ensure an even melt pool and maximize fragrance delivery.

Optimizing Candle Tin Wall Thickness and Bottom Geometry

To ensure an even burn, the next design consideration is the thickness of the candle jar’s walls and bottom. Thicker walls, about 0.4-0.5 mm, retain heat longer, maintaining a stable melt pool, but this will increase the initial preheat time. Conversely, a wall that is too thin (<0.25 mm) can lead to uneven heating and deformation under sustained flame exposure. The ideal wall thickness of the tin is a balance, with tins typically 0.3-0.35 mm thick to speed up initial melting.

At the same time, maintain structural integrity. The geometry of the tin base is also essential: a slightly convex or concave tin base can promote the formation of a central melt pool by directing heat to the interior. Candle tin designers sometimes use thermal simulation software to simulate the heat flow of different tin base structures, ensuring that actual burn tests match theoretical performance. As a candle tin manufacturer, Tsing often uses precision stamping to control the curvature of the tin base, providing reliable and consistent melting patterns from one production batch to the next.

The diameter-to-height ratio for a uniform wax pool

The candle tin’s size directly affects the heat distribution on the wax surface. Wide and shallow tins are conducive to forming a uniform melt pool, which can reach the edges in one burn, thereby reducing wax waste. Standards recommend a diameter-to-height ratio of 2:1 or 3:2. For example, a candle tin with a diameter of 100 mm and a height of 50 mm will achieve the best heat coverage. If the height of the tin is too high relative to its width, the wax may tunnel in the center before melting around the edges. Conversely, a tin can that is too shallow may cause the liquid to overflow, resulting in excessive wax loss.

In addition to helping with heat distribution, the correct ratio improves the performance and stability of the candle wick, minimizing uneven burning. Tin designs optimized with the proper ratio reduce wax residue and maintain their beauty after multiple uses. By applying these ratio guidelines, Tsing can design candle jars that promote edge-to-edge melting and extend burn time.

Ventilation and lid design to support even burning in the candle tin

Proper burning depends not only on the metal material of the tin but also on airflow management within the candle tin. A secure, well-fitting lid helps retain warmth when the candle is not lit, reducing initial cold spots. However, restricted airflow can lead to incomplete burning or soot during the burning process. Some candle tin designs feature small vents or raised lid rims to allow fresh air while retaining heat. Domed lids (such as the round gold tin) can be used on candle tins to capture and redirect warm air back into the tin when the lid is closed.

Quality candles often feature threaded or snap-on lids that create a tight seal, extending shelf life and preserving fragrance, ensuring safe storage and transport. Ventilation design must also meet safety standards to prevent overheating and flame hazards. Ensure candle jars provide balanced insulation and ventilation, which supports a cleaner, more even burn.

Wick placement and compatibility for a consistent heating area

Wick placement and type are also critical to evenly distributing heat. Placing the wick within ±1mm of the tin’s geometric center ensures that the flame’s heat is radiated evenly to the wax surface. A single-wick design is ideal for candle tin lids up to 70mm in diameter. Larger tins may require dual or multiple wicks, spaced according to diameter. For example, two wicks for 80-100mm and three wicks for 100-120mm. In addition, the wick material, such as cotton, wool, or an eco-blend, nd, will also affect the heat output. A denser wick produces a larger flame and more heat, so choosing a wick that suits your tin size and type of wax is also essential.

Surface treatments and coatings that enhance heat reflection

The interior treatment of a candle tin subtly affects how it distributes heat. Matte or lightly anodized interior walls absorb some heat and slightly slow the flow of the melt pool, while polished or reflective interior walls reflect radiant heat into the wax. Some tin manufacturers apply a thin layer of heat-resistant coating, such as phenolic resin, to the inside of the tin to reduce hot spots and prevent chemical reactions with essential oils. Powder coating or printed finishes on the outside should be thermally stable at flame temperatures (up to 120°C) to avoid discoloration or outgassing. Candle manufacturers can carefully select interior and exterior finishes that evenly reflect and absorb heat, ensuring their tins burn consistently and efficiently.

Best Practices for Designing Even-Burning Candle Tins

Designing a candle tin that distributes heat evenly and burns consistently requires a combination of considerations: optimizing wall thickness and base design, following a diameter-to-height ratio, controlling ventilation through lid design, ensuring precise wick placement, and selecting interior finishes that effectively reflect heat

How to solve the odor problem in custom tin cans?

April 27, 2025/in News /by admin

Custom tin cans are widely used to package a wide range of products, from tea and biscuits to cosmetics and candles. However, a common problem that manufacturers and consumers often encounter is odors emanating from the cans. These odors are particularly concerning in the food and cosmetics industries, where freshness and quality are highly valued. The key to solving odor problems lies in understanding the root cause and applying the right solution to ensure a clean, odor-free experience for consumers. In this article, we will explore the causes of these odors and explain how Tsing addresses them to ensure that each can not only has aesthetic appeal but also maintains the integrity of the product.

Identifying the Root Causes of Odors in Custom Tin Cans

Custom tin cans’ odors can come from various sources, each requiring a targeted solution. One of the leading causes is the natural odor that the materials used in the manufacturing process emit. Although durable and protective, tin cans can sometimes emit a metallic odor when first produced or mishandled. Another source of odor is contamination during storage and transportation. Dust, oil, and external chemicals can leave unpleasant odors and affect the overall quality of the can.

Tsing’s approach is to control these factors during production. We rigorously clean and degrease all materials used in custom tins. At the same time, we use state-of-the-art equipment and technology to remove any residue that may cause odors. In addition, we store the finished cans in a constant temperature and humidity environment to prevent external contamination.

Using coatings and liners to prevent odor residue in custom cans

Protective coatings or liners are commonly used in order to avoid odor residue in custom tin cans. These coatings form a barrier between the metal and the can’s contents, preventing any chemical reactions that may cause odors. Certain foods or cosmetics may react with metals to produce unpleasant odors, affecting product quality.

At Tsing, we provide custom liners for custom tin cans to ensure that our customers’ products are protected from external contaminants and internal odor sources. At the same time, we use various FDA-approved coatings, including epoxy phenolic resins, to prevent odors and protect the contents from corrosion. These liners are durable, heat resistant, and prevent any product-metal interactions, preserving the quality and odor of the packaged contents.

The Role of Proper Curing and Ventilation in Odor Control

Improper curing or insufficient ventilation during production can lead to lingering odors within custom tin cans. We must cure the coating properly to prevent odors from trapping. Additionally, we must provide proper ventilation during the storage and cooling phases of production to prevent fumes or odors from trapping within the cans.

Tsing carefully controls the curing process by using time and temperature to ensure that the coating and liners cure properly and remain odor-free. Additionally, utilizing a robust ventilation system on the production floor eliminates any potential fumes generated during the production process, ensuring that the custom cans are ready to use and free of any lingering odors. This multi-step process ensures that our cans maintain their structural integrity and not produce any odors that could affect the consumer experience.

Choosing Quality Materials for Odor-Free Custom Tin Cans

While in itself does not typically produce odors, inferior tin or metals from unknown sources can sometimes produce odors during manufacturing. At Tsing, we prioritize sourcing high-quality, food-safe tinplate and ensure that all materials meet strict industry standards. We also understand that certain products, such as candles or cosmetics, require unique packaging. For example, if we don’t appropriately handle scented candles stored in custom tins, they may absorb essential oils over time, which can affect the freshness of the product. To combat this, we rigorously inspect every batch of custom tins to ensure that we use only the highest quality materials during production.

Packaging Design and Sealing Technology to Prevent Odor Leakage

Packaging design is also critical to keeping custom-tinned products fresh. If we do not seal the tin correctly, even the best materials and coatings will fail. A poorly sealed tin can let in outside air, which may bring in contaminants and affect the product’s smell or, conversely, allow odors inside to escape. At Tsing, we use sealing technology to ensure that the lid of the custom tin fits perfectly to the tin. We rigorously test each screw lid, snap lid, or hinged lid to ensure that it meets our strict airtight standards. This meticulous attention to sealing helps maintain the integrity of your product and prevents any odors from seeping into or out of the can.

Ensure an odor-free custom tin for every product.

Addressing odor issues with custom tins requires a multi-pronged approach that includes using quality materials, applying effective coatings, ensuring proper curing, and using advanced sealing and venting techniques. At Tsing, we have a comprehensive strategy to address all of these factors, ensuring that every custom tin we produce is odor-free and safe for your product. Whether you’re packaging food, cosmetics, or candles, our custom tin solutions can help you maintain the freshness and integrity of your product throughout its shelf life.

Detailed explanation of the core components from the lid to the lining of the metal candle tins

April 25, 2025/in News /by admin

When producing high-quality metal candle tins, every core component, from the lid to the liner, works together to protect the candle wax, retain the scent, and ensure safe use. Many manufacturers and brands consider seal integrity, material compatibility, aesthetics, and heat resistance when selecting metal candle tins. So we will also explore the main parts of metal candle jar components in this detailed overview: removable lids, tin bodies and seams, base design, decorative exterior finishes, interior coatings and liners, and the sealing gasket or sealing ring that completes the package.

Types of metal candle tin lids

The lids of metal candle tins play a key role in fragrance preservation, safety, and branding. Common lid types include:

Slip-on lids: Simply press on the tin’s flange to fit tightly for daily use. Tsing controls the flange tolerance within ±0.2 mm during manufacturing to prevent air leaks that can reduce the candle’s scent.
Screw-on lids: The neck of the bottle has fine threads, and the lid has corresponding threads. This design is extremely airtight, effectively sealing out dust and moisture, making it perfect for limited edition or scented candle collections.
Hinged Lid: Decorative custom metal candle tins often used in high-end gift sets. Tsing spot-weld or rivet the hinges with corrosion-resistant alloys to ensure they withstand repeated opening and closing without loosening.

In addition to the material, the thickness of the lid also affects its sturdiness and ease of access (typically 0.3-0.5 mm tinplate). Tsing adds brushed or matte finishes to the lid to enhance the grip. Quality inspectors also perform torque testing during inspection to measure the force required to open and close the lid, ensuring the performance of thousands of products.

Metal Candle Tins Body Structure and Seam Integrity

The body of a metal candle tin provides structural support, holds the candle, and provides a canvas for branding. Tsing usually make the body panel from tinplate, with the thickness ranging from 0.25mm for lightweight travel tins to 0.5mm for more solid, large-capacity containers. Key considerations include:

Sidewall Forming: Tsing forms the can body using a multi-pass deep-drawing process to prevent wrinkling and ensure uniform wall thickness. Additionally, Tsing uses precision molds and presses to guarantee that the sidewall concentricity remains within microns.
Seam Type: The sides of the two-piece tin are joined with either a lap seam or laser weld, ensuring a smooth, seamless interior to prevent wax or wick residue from collecting. In addition, the seam height is less than 0.5mm to avoid interference with candle liners or labels.
Dimensional Tolerances: Diameter tolerances are controlled to within ±0.15 mm to ensure lid compatibility and consistent fill levels. When Tsing assembles metal candle tins on its production line, it typically controls the height tolerance within ±0.2 mm to provide a uniform appearance.

Automatic lasers measure the critical dimensions of each tin after forming, and the system then rejects parts that fall outside of tight tolerances. As a result, by controlling tin structure and ensuring seam integrity, metal candle tins offer discerning consumers reliable performance, leak-free operation, and an upscale appearance.

Base Design and Structural Stability

The base of a metal candle tin must be able to support the weight of the candle, wick assembly, and any decorative components without warping or tipping. Standard base configurations include:

Flat bottom: creates a slightly raised dome (0.3-0.8mm rise) to prevent vacuum formation during cooling and ease removal from the stamping die.
Recessed foot ring: Shallow grooves near the circumference stabilize the tin on a flat surface and provide a small air gap to dissipate heat while the candle burns.
Anti-slip reinforcements, such as micro-etched patterns or rubber adhesive pads, prevent sliding on smooth countertops, thus increasing safety.

The base material is usually the same thickness as the sidewalls, but larger metal candle tin cans (over 100mm in diameter) can have ribs added to reduce flex. Laser-cut or punched vents minimize airflow at the bottom of the tin, helping to maintain a consistent burn. We also perform drop and compression tests to verify the base’s resilience.

Decorative Topcoats and Protective Coatings

Exterior finishes transform bare metal into an eye-catching brand statement, while interior coatings protect against candle wax and fragrance oils corrosion. Common exterior treatments for metal candle tins include:

Powder Coat: This creates a durable, even finish that resists scratching and chipping. It is available in glossy, matte, and textured finishes.
UV-cured printing: enables high-resolution graphics, metallic inks, and spot varnish effects to highlight logos and product details.
Soft-touch lamination: uses polymer films to create a premium velvety feel for a tactile experience.

A 3—to 8-micron-thick food-grade or candle-safe lacquer is applied to the interior to prevent the metal from interacting with the wax, which can cause discoloration or change the tin’s scent. In addition, some metal candle tin cans are coated with multiple layers of coatings, such as primer, corrosion-resistant layer, and topcoat, to extend their durability in humid environments.

Liners and heat-resistant barriers for metal candle tins

The lining of metal candle tins not only ensures chemical compatibility with the wax but also stabilizes heat transfer and simplifies cleaning after burning. Additionally, core options include:

Epoxy Phenolic Lining: This lining provides excellent adhesion and continued protection against wax migration and metal corrosion, rated up to 150°C.

Silicone-based high-temperature coatings: Expand and contract with the wax, minimizing cracking and flaking under thermal stress.

PTFE linings: Used in specialty cans for certain soy or gel wax formulations, providing a non-stick surface and easy removal of residual wax.

Liner thicknesses typically range from 5 to 25 microns, with thin coatings susceptible to high-pressure pinholes, while thicker coatings may crack. The installation used an automated spray system equipped with precision nozzles to ensure even coverage, and the lining was cured under infrared lamps at a controlled temperature. Additionally, after curing, the tanks were placed on a mandrel and tested at 120°C for two hours to confirm the integrity of the lining.

Adding a Sealing Gasket for Quality Assurance

After metal candle tin cans are assembled, a sealing gasket or ring is added to ensure that the lid-to-tin connection remains airtight during storage, thereby retaining fragrance and preventing dust ingress. The gasket’s cross-sectional thickness ranges from 1 mm to 3 mm, and its elasticity must maintain compression during temperature cycles (-20 °C to +50 °C).

To ensure quality:

Seal integrity testing: measuring air leakage rate under five bar differential pressure.
Thermal cycling: exposing the assembled tins to freeze-thaw and high humidity conditions.
Long-term storage testing: monitoring fragrance retention for up to 12 months.

By combining robust gasket design and rigorous quality assurance with the comprehensive insights detailed above—including lid tolerances, tin construction, decorative surface treatments, and heat-resistant linings—Tsing therefore ensures that it can confidently produce custom metal candle tins that are not only functional but also aesthetically pleasing and highly reliable.
