Electrolytic Tinplate undoubtedly enjoys the pride of place as a packaging medium especially for food. It owes its unique position to its "nine layer sandwich structure", each of which contributes to its eminence as a packing material. The steel base provides the necessary strength and formability for can fabrication. The tin-iron alloy layer provides the bond between the steel and free tin layer. The free tin layer is not only responsible for the attractive bright finish and ease of solderability but is also non-toxic- a factor of vital importance in food packaging!
Electrolytic TinPlate: Composition
E.T.P. consists of five layers each of which performs a different role:
1. Steel Base: Provides stiffness to the material due to its thickness and mechanical strength. Its chemical composition imparts special properties to resist corrosion.
2. Iron-Tin Alloy: This is made up by the inter-metallic compound Fe-Sn2. Due to its electrochemical characteristics, it acts as a barrier against corrosion. For effective action, its continuity is more important than its quantity.
3. Metallic Tin: Tin has many advantages which have turned it into the most important element to protect steel used for cans; in many foods, it acts as a simple barrier against corrosion, improves weldability, it is an excellent base for lithographic printing and for applying lacquers. In tin-robbing foods, it acts as a sacrificial element.
4. Passivation Film: According to its nature, it makes it possible to improve the E.T.P.’s resistance to sulphiding, oxidation and rust. It is also a conditioner to improve the adherence of varnishes, inks, lacquers etc.
5. Oil Film: Protects the sheet from the humidity in the environment and makes easy to handle. It is applied using an electrostatic oiler on both sides of the sheet.

FAQ of Lacquered Tinplate for Metal Packing sheet Coils
How long does it take to get the product if i place an order?
With the process of your requirements,we will pack and deliver in 3-7 days.If it is by sea shipment,it will take 15-45 days depending on different locations.
- Q:How to test the tightness of tin metal cans?
- The empty tank which has been cleaned can be dried by 35, and the pressure or pressure leak test shall be carried out according to the equipment condition of each unit. B.1 pressure leak test, the empty tank will be carefully injected into the water until eight or nine into full, the rubber ring will be placed in the appropriate plexiglass plate at the opening side of the roll, so that it can be sealed. Start the vacuum pump, turn off the bleeder valve, hold down the cover by hand, control the pumping, and make the vacuum gauge rise from 0Pa to 6.8X10 PA (510mmHg) for more than 1min, and keep the vacuum above 1min.
- Q:What is the difference between Maguchi Tetsu tinplate and galvanized board
- Zinc plating on the surface of thin steel plates and steel strips by continuous hot dip plating prevents corrosion of the surface of thin steel plates and steel strips. Galvanized steel sheet and steel strip are widely used in machinery, light industry, construction, transportation, chemical industry, post and telecommunications and other industries.
- Q:Can tinplate be shielded?
- With the production of mobile phone shielding materials I know the ocean (Cupronickel), copper, tin phosphor bronze (TIN), these three kinds of material weldability are very good, because the surface of tin!
- Q:What is the process of two cold rolling of tinplate?
- Tin plays a major role in preventing corrosion and rusting. It will be the steel strength and formability and corrosion resistance of tin soldering, and beautiful appearance with a material, corrosion resistant, non-toxic, high strength and good ductility properties.
- Q:What material is the tin plate, please?
- Tinplate is a tin covered with tin, it is not easy to rust, also known as tin iron
- Q:How can tinplate be identified?
- The quality of tinplate is related to the final use.
- Q:Why tin printing after a layer of light oil
- Varnish should have the following properties:A) the color retention property is good. The solvent in the varnish can not make the ink fade and fade.(b) have sufficient hardness and firmness in order to withstand the deformation of subsequent processes.(c) match with white paint or base oil, not to corrode white paint or base oil.
- Q:Tinplate which applies to product packaging?
- Barrier: tinplate cans have excellent barrier properties than any other materials are excellent, gas barrier properties, moisture resistance, shading and aroma were good, and the sealing is reliable, reliable protection products. 3. mature technology and high production efficiency: the production of tinplate has a long history, mature technology is a set of production equipment with matching, high production efficiency, can meet a variety of product packaging needs.
- Q:What about tin cans?
- In the galvanic cells of the tin, iron is negative and oxidized because iron is more active than tinTherefore, in the coating damage after corrosion. Than tin tin
- Q:Why do tin tins rust easily when they are opened?
- Tin iron loses electrons and gets an electron redox reaction to accelerate the corrosion process
