Tinplate cans typically have a smooth surface with a metallic sheen. This is because the tin coating itself creates a silvery-white reflective effect, while the coating and printing also contribute to the can's glossy appearance.
Tinplate cans offer excellent sealing properties. Sealed with a roll-to-seal method, they prevent air from easily entering. Their seal not only blocks air but also effectively prevents moisture from entering, making them particularly suitable for coffee products that require dry storage.
The recycling process for tinplate cans is relatively simple, and the recycling rate is very high. Recycled tinplate cans are first cleaned and treated to remove impurities. The metal is then melted to extract the iron and tin. These extracted metals can be reused in the manufacture of new metal products.
Condiments such as soy sauce, vinegar, and chili sauce typically contain high levels of water and acid. These properties make them susceptible to moisture and oxidation during storage. Tinplate cans, with their tin plating and inner coating, effectively isolate air and moisture, preventing condiments from deteriorating due to moisture.
In certain industries, such as food and cosmetics, where demanding product packaging is required, tinplate cans may be more expensive than other packaging materials. However, their value lies in their superior pr
Food safety is a crucial consideration in the packaging industry. Tinplate cans have proven themselves to be extremely safe as food packaging materials over many years.
The protective effect of the tin layer is limited, especially when storing acidic foods, where there is a risk of tin corrosion. Therefore, during the production process, a protective coating or lining is often added to the inner surface of tinplate cans to further prevent direct contact between food and metal.
Tinplate packaging cans are widely used for beverages and liquid foods, especially products that require a good seal, such as carbonated beverages and beer.
Tinplate packaging cans are not suitable for packaging foods with high acidity or high salt content, such as ketchup, fruit vinegar, and preserved foods.
Candy cans need to have a certain hardness to protect the food inside, which requires the can body to be sturdy and avoid deformation during transportation and storage. Tinplate sheet has such characteristics. Its core is steel, which gives the can body excellent pressure resistance and hardness.
