Treatments for the food industry

In a highly developed industry such as the food industry, metal treatment is a widely used processing. They are performed both on product containers (the purpose is to preserve pack integrity) and for the production systems (machinery) needed during the production cycle.

The most commonly used treatments fall into the category of functional processing, and there are essentially two: thick chrome plating and tin plating. Thick chrome plating is used for the specificity of chromium, which, deposited thickly, possesses high wear resistance and high oil-holding capacity. Tinning, an electrolytic process by which metallic tin is deposited, is used because it prevents corrosion of food containers: in fact, cans and tins, with tinplate (tin-plated steel sheet), have always been widely used for food preservation.
