Product Description:

1.Structure of Electrolytic Tinplate (ETP) for Foods and 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) for Foods and 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:Does the tinplate have a tensile rate? Thank you heroes!
Yes, what does it look like?. Deep drawing pot should be higher tensile rate (also known as elongation), the harder the material, the lower the tensile rate; the industry generally does not have a uniform tensile rate, generally in order to replace the cup burst value test.
Q:Tin plated tin plated?
Because of the punching after the incision site no tin layer, while most parts of surface layer of tin, the pretreatment process of adverse, removing tin layer will damage the substrate without removing the tin layer if not plating parts difficult to achieve uniform effect
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:Both tinplate and stainless steel have corrosion protection
Tinplate is common steel tin plating, tin coating is broken, later, because the tin is more corrosion resistant than iron, so iron will sooner corrosion. Mainly used for tins.
Q:Raw material for zinc clad sheet? Can zinc clad plate replace tinplate?
Zinc is very active, outdoor corrosion is the surface after the formation of Zinc Oxide, do you dare to drink drinks containing Zinc Oxide, you see, you can replace the tinplate?
Q:How can the section of the tinplate be maintained without rust?
The cross section of the tinplate is free of rust. Both sides have plating, the cross section can use lubricating oil
Q:What is tin plate
Tinplate is classified according to thickness and tinning. Generally speaking, in order to save costs, the current industrial production will reduce the iron thickness and tin content while guaranteeing the reliable strength of the package. One is to use less or even no tin tin (chrome iron), by 50s the development of hot dip tin plating tin to the present, China has not see the hot dip in the use of tinplate cans.
Q:What is the difference between food grade tinplate and ordinary chemical tinplate? What is the difference between MR material and SPCC?
No general food grade and ordinary chemical tinplate tinplate. There are some major is not mature in domestic tin (MR, L, D) the production of tinned steel substrate outside, technology is not mature, not environmental protection, so there is a risk for food cans, can only be used for chemical tank.
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:What's the head iron?
Tin plate (commonly known as tinplate) refers to the surface coated with a thin layer of metal tin steel plate. The corrosion resistance of SPTE is poor, the general condition of 24H will appear rust smoke test.
