Can custom tin cans be food-grade?

There are many applications for custom tin cans, and when facing some food brands and manufacturers, they will ask us whether custom tin cans are food grade. The answer is yes. We will explain in this guide so that different brands and manufacturers know that our custom tin cans are suitable for storing various foods.

Custom tin cans with food-grade safety standards

The primary material used in custom tin cans is tinplate, which is steel coated with a thin layer of tin. This coating acts as a protective barrier against corrosion and contamination. We also use food-safe lacquer as a coating for the interior. This lacquer prevents any potential reaction between food and metal, further ensuring the safety of the stored products. The manufacturing process of these cans involves strict quality control measures to maintain hygiene and prevent any impurities from compromising the integrity of the food.

Regulatory standards for food-grade custom tin cans

To ensure that custom tin cans are food-grade, we must comply with various regulatory standards set by health and safety authorities, including the US FDA, which has set guidelines for food-safe packaging materials, and the European EFSA, which oversees similar regulations. These regulations cover everything from the materials used in manufacturing to the production process. For example, the FDA’s Title 21 of the Code of Federal Regulations (CFR) outlines specific requirements for materials that come into contact with food, including tinplate and coatings. We provide documentation and test results demonstrating that our custom tin cans meet these standards.

Overall Manufacturing Process

The manufacturing process for custom tin cans involves several key steps. First, tinplate is produced by coating steel with a thin layer of tin. The tinplate is then formed into the desired can shape through stamping or drawing.

After the cans are formed, they are thoroughly cleaned to remove any residue from the manufacturing process. The inside of the cans is then coated with a food-safe lacquer that cures at high temperatures to create a durable protective layer. This lacquer prevents any interaction between food and metal, preserving the integrity and flavor of the food. Once completed, they are tested to meet all safety and quality standards. This includes testing for material integrity, coating adhesion, and overall durability.

What are the benefits?

The reason for using food-grade custom tin cans to store food is that they meet relevant regulatory standards on the one hand, and on the other hand, they can give your consumers the confidence that the food inside will not go bad over time. Their main advantage lies in their excellent barrier properties. Tin cans can effectively block light and oxygen to maintain the freshness of food better. Another essential advantage is durability. Unlike other tin box packaging materials that are easily deformed, the tinplate is very strong and easily damaged. This makes them suitable for various foods, including those that require sturdy packaging for transportation and storage.

More environmentally friendly

Many tin can manufacturers will not notice this aspect, but it is the most important. We live in an era of environmental awareness, and the sustainability of packaging materials is an important consideration. From an ecological perspective, tin is a recyclable material that can be recycled multiple times. Tin cans are a more sustainable choice than single-use plastic packaging. In addition to storing food, they are also suitable for storing other daily necessities.
