Tinplate, also known as tinned iron, is the common name of tinplate steel sheet, abbreviated as SPTE, which refers to cold-rolled low-carbon steel sheet or strip coated with commercial pure tin on both sides. Tin is mainly used to prevent corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin in one material, and has the characteristics of corrosion resistance, non-toxic, high strength and good ductility. Because of its unique physical and chemical properties, bright color printing technology, convenient transportation and other factors, Tin Boxes has become an important choice for product packaging, and therefore is also a preferred packaging method for major platform businesses.
