Food Grade Tinplate Strip

Electrolytic tinplate coils and sheets used for metal food packaging are thin steel sheets coated with tin coating through electrolytic deposition. The tinplate produced through this process is essentially a sandwich in which the central core is strip steel. The core is cleaned in an pickling solution and then passed through a bath containing an electrolyte with tin deposited on both sides. As the strip passes through a high-frequency electric induction coil, it is heated, causing the tin coating to melt and flow, forming a shiny coating. Tinplate food-grade beverage packaging materials are widely used in food, chemical, industrial and other industries, such as food cans, beverage cans, grease cans, grease cans, chemical cans, spray cans and other miscellaneous cans. Its main feature is to support the protection of the physical and chemical properties of the contents. Therefore, the quality standard of tinplate is very important for the packaging and protection of the contents, so a correct understanding of the quality and standard of tinplate is the basis for understanding canning and one of the main keys to the success of canning.
