Iron can is a material that combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin in one material, in which tin mainly prevents corrosion and rust. It has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility. According to the characteristics and needs of their products, tea tin box manufacturers choose bright tin or matte tin to achieve corrosion resistance. Iron cans are a good packaging material. After tinning the tea tin box, in addition to the basic protection function, it also has a good decorative and beautifying effect.
There are two types of tin on tin boxes or cans: one is bright tin, which, as the name suggests, has a bright appearance, looks better, is smoother, has fine crystals, is not easy to leave fingerprints, and generally has a thickness of more than 3um; the other It is matte tin. Relatively speaking, its appearance is foggy, the crystal is relatively rough, and it is easy to leave fingerprints. Generally speaking, its thickness ranges from 5um to 8um.
Tinplate packaging has many advantages, such as high strength, good formability, and strong product compatibility, which have established a good "word of mouth" in the international market. Therefore, in general, the inner coating of the tea iron box is a tin-plated material, which can improve the corrosion resistance of the steel plate. Because the outer layer of the tea leaves will also have paper or other packaging in the iron box, which not only does not harm the tea leaves, but also protects the tea leaves.
