How do you ensure that custom cookie tins are corrosion-resistant?

April 9, 2024/in News /by administrator

When storing biscuits, the corrosion resistance of the cookie tins can directly affect the quality of the biscuits. Poor corrosion resistance will lead to moldy biscuits and other problems. Therefore, many biscuit manufacturers choose to custom cookie tins to ensure the corrosion resistance of the cookie tins. As a supplier with many years of experience in customizing tin box packaging, Tsing will share with you in this guide how we ensure the corrosion resistance of custom cookie tins.

Material Selection for custom cookie tins

Tsing’s custom cookie tins are primarily made from tinplate, a type of steel coated with a thin layer of tin that resists deformation or damage. The sturdy nature of tinplate ensures that custom cookie tins can survive bumps in transit without compromising the integrity of the interior. The corrosion resistance of tinplate can protect the biscuits from spoilage caused by air moisture and other factors. Its tin coating acts as a barrier to prevent oxidation and moisture ingress, thereby extending the shelf life of the biscuits. This is very important for long-term storage!

Custom cookie tin finishes and coatings

Regarding surface treatment and coating technology for customized cookie tins, Japan’s latest printing machine produces metal prints daily, such as CMYK or Pantone, matte, etc. Allows you to add decorative patterns and logos to your cookie tins to enhance visual appeal. Regarding coatings, we use environmentally friendly and safe coatings to ensure your cookie tins are non-toxic, odorless and meet the highest safety and quality standards. We also offer powder coating technology if you need it, where we apply dry powder to the surface of the can, heat it, and cure it to form a tough protective coating. Make sure the cookies retain their appearance even after repeated use.

Custom cookie tin sealing mechanism

Another factor that ensures the corrosion resistance of custom cookie tins is the sealing performance of the tin. We will use double crimp seals on the tin body and bottom to form a tight seal to prevent moisture and odor from entering the tin, enhancing the sealing performance and use—longevity and freshness of cookies and other foods. In addition, we will also add lids with metal clips to the customized cookie tins according to your needs to increase the tightness of the lid closure.

Durability test

Before each custom cookie tin is delivered, we conduct a durability test, one aspect of which is to evaluate the impact resistance of the cookie tin. It will be subject to controlled impacts at different angles and heights, simulating real-life scenarios where cans may be accidentally dropped or knocked over during handling and transportation. This evaluates the cookie jar’s ability to withstand impact forces while maintaining structural integrity. Another aspect is evaluating the compressive strength of custom cookie tins. We will gradually increase the pressure on the cookie jar, simulate the weight of the stack of jars during storage and transportation, and measure the maximum load that the cookie tin can withstand and avoid the risk of damage during transportation and storage.

Regular maintenance and upkeep

Although our custom cookie tins are highly corrosion-resistant, you must take proper care during your daily use. Especially if you put it in a storage cabinet that is prone to gathering dust, you need to use a cloth to gently scrub the surface or rinse the tin thoroughly with water and dry it with a soft, lint-free cloth. We recommend storing the cookie tin in a relaxed, dry, well-ventilated environment away from direct sunlight. Excessive heat, humidity, or exposure to sunlight can cause the jar’s finish to fade, compromising its appearance and performance.

The importance of corrosion resistance

The corrosion resistance of custom cookie tins is significant to the quality and preservation of freshness of baked goods. If we don’t add corrosion resistance, your users will likely eat stale biscuits. In Tsing, we can ensure that the biscuit jars you receive are of good quality by using tinplate materials, advanced printing machines, coating technology, and sealing technology.

Why is durability so important for bulk tea canisters?

Durability ensures the integrity of loose tea cans, protecting tea leaves from external factors such as moisture, light, air, etc. Because loose tea is highly susceptible to degradation when exposed to the elements, resulting in a loss of flavor, aroma, and potency over time.

Tinplate is steel coated with a thin layer of tin that acts as a protective layer against corrosion, rust, and moisture. It is also food-grade safe, non-toxic, with smooth edges and no burrs. The material’s inherent resistance ensures that the tea leaves remain intact when stored, maintaining quality and freshness.

So, in this guide, we will focus on this part and share with you the various options for customizing the tea tin base.

Material selection for custom tea tins bottoms

When customizing the bottoms of tea tins, Tsing often uses tinplate, a thin steel plate coated with a layer of tin to prevent corrosion. In addition, tinplate has excellent molding plasticity, allowing us to use complex design and embossing techniques to create a visually attractive bottom during the design process. In addition, the moisture resistance of the tinplate will be better, which can maintain the flavor and freshness of the packaged tea. Another option is aluminum, which some customers also choose for customization due to its lightweight, high corrosion resistance, and recyclability.

After selecting the material and pattern printing effect, Tsing can also provide a range of sizes and shapes for you to choose from. Of course, you can choose according to your own preferences and packaging requirements. Generally, the primary consideration when selecting the size of the base of a tea tin is the volume or capacity required for the amount of tea you want to hold, which will usually match the size of the lid of the tea tin. In terms of shape, you can choose traditional shapes, such as circles, squares, and rectangles, such as lids. You can choose heart shapes for certain holidays combined with specific pattern printing to highlight the unique style.

How to choose the right candle tins for your candle business?

August 19, 2021/in Candle Tins, News /by administrator

If you just start your candle business and don’t know what kind of candle tin you will choose for your start-up business, this article will help.

Currently there are kinds of different shapes and structure candle tins in the market, round, square, rectangle, egg, heart and many other different candle tins. Whatever shape you choose, there is one very important thing you need to confirm, that is, the tin container will not leak when store candle wax.

In the market, the candle tins can be divided into two kinds of structures, one is seamless tin and the other is the seam tin.

Let’s talk about the seamless candle tins first, the seamless candle tins won’t leak when storing candles. But it has disadvantages, as it uses body and base one-body design, there is a stretch process in production, so it will limit the artwork design. We suggest to use just one color or irregular artwork design, as regular shape (such as squares, circles, triangles, words) will be out of shape after the stretching process.

Then it’s to the seam candle tins. For the seam candle tins, let’s divide it into the body seam area and the bottom seam area.

The body seam can have the welding process and the normal seam connection process. If you choose the welding process tin, then we are also sure that it won’t leak if used to store candle wax. But it has a disadvantage, the body welding area can’t print artwork design, and it will only be the silver, which is the color of tinplate.

As to normal seam connection process for body, then the bottom seam area can be curved in process and the curved out process. Let’s talk about the body normal seam connection process + bottom curved out process first, for this kind of candle tins, we will use glue at the connection area to confirm it won’t leak when store candle wax. We can confirm with this operation, the tin won’t leak. And this kind of tin won’t limit the printing artwork design.

Then it’s the normal seam connection process + bottom curved in process, for this kind of tin, even if we use glue at the connection area, we can’t confirm it won’t leak when used to store candle wax. So we don’t suggest to use this kind of tin to store candle wax.
