Tinplate is commonly known as "Ma Kou Tie" in Chinese, which is a transliteration from Macao as Macao is the major port for the import of tin plates into China.
Currently, all tinplate products in use are electrolytic tinplate (ETP) and tin free steel (TFS), which are important raw materials for manufacturing metal pack.
Tin Free Steel also is known as Electrolytic Chromium Coated Steel (ECCS) is a thin, cold-rolled carbon steel sheet coated by electrolytic deposition with metallic chrome overlaid with a film of chrome oxide.
The Structure of Electrolytic Tinplate（ETP）
Electrolytic tinplate is composed of five layers, including base steel, iron-tin alloy, tin, chromium oxide, and oil film. However, some people believe that it is made up of six layers; that is, there is a tin oxide film beneath the passivation film. Sometimes, the tin oxide film and the passivation film are collectively known as the oxidation film.
The Structure of Tin Free Steel（TFS）
Generally, it is believed that the tin free steel (TFS) is composed of four layers, including steel base, metallic chromium layer, chromium oxide layer and oil film.

The Production Process of Electrolytic Tinplate（ETP）
The major steps of the electrolytic tinplate process include:
Uncoiling → Cutting → Alkaline cleaning → Straightening (or before alkaline cleaning) → Pickling → Electrotinning → Reflowing and hardening → Passivation → Quality inspection → Coiling.
The Production Process of Tin Free Steel （TFS）
Major steps of TFS line are as follows:
uncoiling → welding → looping → alkaline cleaning → tension leveler → pickling → metallic chromium electroplating → chromium oxide electroplating → electrostatic oiling → looping → trimming (circle shear) → quality inspection → coiling.
The Production Process of Lithography Tinplate
The major steps of the Lithography Tinplate line are as follows:
Tinplate dust removal & wrinkle treatment → Internal lacquer coating → Drying → Bottom layer printing → White color printing → Drying → Graphics printing → Drying → Varnish lacquer coating → Drying.
