1.Structure of Electrolytic Tinplate for Useage of Food Package Description
Tin plate is a thin steel sheet coated by tin. The thin steel sheet on which tin coating is done is known as black plate. Tin has several properties which make it suitable for use as a coating on steel. It has a good resistance to corrosion in a wide range of environments and in particular retains its appearance and surface properties extremely well in indoor atmosphere. It is easily soldered and the good corrosion resistance ensures effective retention of solderability. It is safe in contact with foods, neither producing risks to health nor impairing flavours. The softness of the metal, although disadvantageous for some uses of coatings, has merit for others, facilitating cold working, giving easy running threads on fasteners and helping to seal joints. Tin coatings are applied either by hot dipping or electrolytically coated. Both processes produce coatings which have characteristics of their own. Hot dip tin coating has advantages in being metallurgically bonded to base steel and of producing a smooth bright surface. Electrolytically coating is able to produce a uniform coating of controlled thickness. With electrolytically coating steel sheet can be differentially coated. In such coating heavy side coating is usually marked.
2.Main Features of the Electrolytic Tinplate for Useage of Food Package
Appearance – Tinplate is characterized by its beautiful metallic luster. Products with various kinds of surface roughness are produced by selecting the surface finish of the substrate steel sheet.
Paintability and printability – Tinplates have excellent paintability and printability. Printing is beautifully finished using various lacquers and inks.
Formability and strength – Tinplates have got very good formability and strength. By selecting a proper temper grade, appropriate formability is obtained for different applications as well as the required strength after forming.
Corrosion resistance – Tinplate has got good corrosion resistance. By selecting a proper coating weight, appropriate corrosion resistance is obtained against container contents. Coated items should meet 24 hour 5 % salt spray requirement.
Solderability and weldability – Tinplates can be joined both by soldering or welding. These properties of tinplate are used for making various types of cans.
Hygienic – Tin coating provides good and non toxic barrier properties to protect food products from impurities, bacteria, moisture, light and odours.
Safe – Tinplate being low weight and high strength makes food cans easy to ship and transport.
Eco friendly – Tinplate offers 100 % recyclability.
Tin is not good for low temperature applications since it changes structure and loses adhesion when exposed to temperatures below – 40 deg C.

5.FAQ of Electrolytic Tinplate for Useage of Food Package
- What is tinning and how does it work?
Tinning is the process of thinly coating sheets of wrought iron or steel with tin, and the resulting product is known as tinplate. It is most often used to prevent rust.
