1.Structure of Electrolytic Tinplate Sheets for Foods 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 Sheets for Foods 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:Both tinplate and stainless steel have corrosion protection
Stainless steel is added in the iron, Cr, Ni and other corrosion-resistant materials, is fundamentally changed the anti-corrosion properties of materials.
Q:The difference between a matte tin plate and a bright tin plate
Silver tinplate:Silver surface processing refers to the original plate in plating passivation treatment after reflow treatment and the surface has a unique stable luster; after printing and coating, the operation of creating a gorgeous and elegant atmosphere, used in the manufacture of advanced art cans, nuts, etc..
Q:Advantages and disadvantages of tinplate packaging
Because of these properties, so can provide a besides the heat, completely isolated from the closed system of environmental factors, avoid color food because of light, oxygen, moisture and deterioration, nor because of aroma through and become weak or affected by environmental pollution through the smell and taste, stability is better than that of other packaging materials of food storage. Vitamin C save the highest rate, nutrient retention is the best. International environmental management standards will be implemented soon based on ISO-14000, has the advantages of low pollution, tin recycling, resource characteristics, in the future packaging applications, will have a broader space for development.
Q:How do you paint the tinplate?
Looking for tin printing cans factory processing back. Printing waste rate of 1000, there are 5 waste or so.
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 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: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:Tinplate which applies to product packaging?
It is suitable for the packing of tea, moon cake, candy, biscuit, health care product and so on.
Q:How to quickly distinguish tinplate and ordinary substrate iron?
Tinplate is tin coil, measurement of tin content?. The base plate is a plain hard rolled coil, which is relatively hard without annealing.
Q:What are the causes of tinplate rusting and how to prevent them?
Invasion of water. The water is on the iron sheet to form a galvanic cell. This should keep the environment dry. Besides, the temperature difference between the iron sheet and the environment should not be too great to avoid the moisture in the air falling out on the sheet iron.
