Tinplate is a thin sheet steel (black plate) coated, within the production process, with tin on both sides by means of tinning process. Depending on relationship of coating thickness at the sides, tinplate can be produced with either equal or differentiated thickness of coating.
Tinplate is offered in coils and sheets, according to standards GOST 13345-85 (the USSR), GOST R 52204-2004 (Russia), EN 10203:1991, EN 10202:2001 (European Union), ASTM A 623/98 (the USA).
Advantages from tinplate use:
Corrosion protection of the material due to electrolytic tin plating.
High level of a package protection against dirt, bacteria, moisture, light and odour during production, due to tinplate chemistry.
Tinplate is sufficiently strong material, so, with sound approach to the package design, the product will show high strength properties, internal pressure proofness, air-tightness and impact resistance. So these qualities improve the transportation of products and provide easy storage of all types of goods, reduce the cost of manufacturing and trading companies.
Tinplate is resistant to solvents (primarily, to organic ones), that is why it is suitable for chemically active substances packaging (lacquers, paints, solvents, etc.).
The major consumer of tinplate is food canning industry, where it is used for the production of tin cans and tin lids for glass jars. Further, tinplate is used for the production of aerosol cans and package for paintwork materials and petrochemical products.
