Tinplate is a composite material with a layer of tin on the surface of low-carbon steel. It has the strength of steel and the corrosion resistance of tin, so it is widely used in packaging in the fields of food, chemicals, cosmetics, etc.

Aerosol cans must withstand internal gas pressure, and the strength of the material is crucial. The basis of tinplate sheet is steel, which itself has high strength and rigidity and can withstand large external impacts and internal pressure.
