Tinplate-what is Tinplate ?
SPTE is the abbreviation of "Steel Plate (or Strip) Electrolytically Tinned", and the Chinese translation is "electrolytic tinned steel plate (band)". This is a thin steel plate or strip that is electrolytically tinned and coated with a thin layer of tin on the surface of the steel plate.SPTE is mainly used in the food packaging industry, especially the manufacture of metal food cans. The tin layer plays a role of anti-rust and anti-corrosion on the food contact surface, and at the same time can keep the food fresh and nutritious, because the tin layer can effectively isolate the contact between the food and the steel plate, and avoid the chemical reaction between the food and the steel. In addition, the tin layer also endows SPTE with better welding performance, making the sealing of the tank more reliable.
