Product Description:

1.Structure of Electrolytic Tinplate (ETP) Coil and Sheets for Chemical Packaging Description


Electrolytic Tin Plate Coils and Sheets for Foods Metal Packaging,  is one thin steel sheet with a coating of tin applied by electrolytic deposition. Tinplate made by this process is essentially a sandwich in which the central core is strip steel. This core is cleaned in a pickling solution and then fed through tanks containing electrolyte, where tin is deposited on both sides. As the strip passes between high-frequency electric induction coils, it is heated so that the tin coating melts and flows to form a lustrous coat.


2.Main Features of the Electrolytic Tinplate (ETP) Coil and Sheets for Chemical Packaging


Appearance – Electrolytic Tin Plate 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 – Electrolytic Tin Plates have excellent paintability and printability. Printing is beautifully finished using various lacquers and inks.

Formability and strength – Electrolytic Tin Plates 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 – Electrolytic Tin Plates 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.

Q:Why tinned fruit cans, some snow wall, and some inner wall does not appear?
The same is canned fruit, tin cans taste more than glass bottles, why is it better? Because the storage process is completely isolated from the sun, so that it can retain the original flavor of canned fruit.
Q:How can tinplate be rustproof? Products must not be oil
It has good salt spray resistance, drainage performance and resistance to hand sweating. It has a long time of rust prevention.
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:What is the use of tinplate printing tin, storage of food safety
Tinplate was first imported into China from abroad. It is a kind of iron with better quality and is made of extremely thin iron sheet
Q:Soup with tin cans loaded also need high temperature sterilization?
Recently, the new provisions of the food industry has been introduced, did not look carefully, it seems that there is no preservative food should be high temperature sterilization.From the point of view of food safety, sterilization is also beneficial. You know that.
Q:And what are the main packing materials?
The difference between the two cans is usually called a tin plate of three cans. The material is usually made of tin and hence its name. Canned container used for beverage, dry powder, chemical product, aerosol product.
Q:Tin cans and tin cans, which is good?
I think this question is not asked to tin tin, chrome tin and galvanized tin which is the best? Of course, the best is galvanized iron. The second is the tin tin, followed by chrome tin, iron box is made finally.
Q:What material is the tin plate, please?
Popularly speaking, it was tin plated on the surface of the iron sheet, just because it was imported by Macao at that time, so it always called "tinplate iron"
Q:What are the causes of tinplate rusting and how to prevent them?
The tin surface of the iron sheet is injured and exposed during the machining process to promote corrosion.Prevention: 1, not coated iron sheet, coated with oil after plating thickening. Effectively prevent water invasion and reduce damage to the process.2 can be painted on the iron sheet of appropriate paint, blocking the impact of corrosive substances.
