Introduction
Tin mill sheet steel is used to produce food packaging and other containers. It is available as black plate, tin plate and tin-free steel (TFS). Black plate is an uncoated thin gauge cold-rolled steel intended for use in the untinned state or to produce other tin mill products. Tin plate is black plate, electrolytically plated with metallic tin through an acid or alkaline process. TFS is black plate that has been electrolytically plated with metallic chromium and chromium oxides.
Both tin plate and tin-free steel undergo a plating process whereby the molecules from the positively charged tin or chromium anode attach to the negatively charged sheet steel. The thickness of the coating is readily controlled through regulation of the voltage and speed of the sheet through the plating area.
Tin mill products have been shown to be a product of choice for canning and preserving food as the shelf life of food in such products is generally two years.
