The crown cover is a stamped tinplate, generally made of T4 material with a thickness of 0.22~0.24mm and a hardness of HR30Tm of 61 ± 3. There are two types of surface plating: tin plating (SPTE) and chrome plating (TFS). With the development of the food packaging industry, it is proposed to reduce the thickness of the crown cover, increase the strength, and use low-cost chrome plating (TFS) instead of tin plating.
