1： Corrosion resistance. As tin is plated on the surface of SiFe bottle cap, which can play a good role in placing corrosion and rust, the bottle cap has a very good corrosion resistance, and will not rust in application.

2： Non toxic. From the detailed material and raw material cost, the Ma Si iron bottle cap does not contain any substances harmful to human health, so it has non-toxic characteristics and can be used in food packaging.

3： Good ductility. Sitie is a kind of material with very good ductility, so it can be easily made into a relatively thin bottle cap with a large plane area.

4： High strength. Si iron bottle cap has high strength and will not be deformed randomly, so it can adhere to stable sealed packaging in application.

Corrosion resistance, non-toxic, good ductility and high strength are the four characteristics of tinplate bottle caps, which are bound to have a stable and reliable seal in packaging.
