The vast majority of food packaging with tinplate steel base. Less residual trace elements, with excellent corrosion resistance.

Chrome-plated coil is also called Wuxi steel coil, abbreviated as TFS, which is a new type of canning material developed for the situation of low metal tin resources and high cost. Compared with tinplate, it has the advantages of low price and strong coating adhesion, but it is not as good as tinplate in corrosion resistance and appearance gloss, and it cannot be soldered at present. It can only be welded or bonded by lap resistance welding. At present, it is mostly used for processing crown bottle caps and weak acid food cans. In recent years, its use has gradually become widespread.

Electrolytic tinplate integrates the advantage of steel and tin. It brings excellent properties of form-ability and strength, paint-ability and printability, solderability and weldability, corrosion resistance and beautiful appearance. Tinplate also has nontoxic and good ductility properties. It is widely used in food, medicine, commodity, instrument and general packaging.
