Why is TFS steel is the best materials for metal packing ?
TFS (Tin Free Steel, also known as ECCS, Electro-Chromium-Coated-Steel). is produced by applying electrolytic chromic acid treatment over steel sheets so that they are coated by a thin film composed of lower layer metallic chromium and upper layer chromium hydroxide.
Its price is slightly cheaper than tinplate. It is mainly used for producing can lids or ends, two pieces cans (drawn cans) and crown caps.
TFS has excellent lacquer adhesion properties allowing use for food cans, beverage cans and general line cans.
Excellent resistance to black sulfide stain makes it the most suitable material for making fish cans.
Even when the same surface finish as TIN PLATE is applied to the substrate steel sheet,
it provides the unique surface luster characteristic of metallic chromium.
