Product Description:

1.Structure of Electrolytic Tinplate in Coils for Foods Tin Packing 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 in Coils for Foods Tin Packing


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:Tinplate also known as what? What is the density of it?
This kind of galvanized steel in a long time Chinese called "tin", some people think that the tin plate when the manufacture cans from Macao (English Macao for tinplate imports, readable) so called "tin".There are other statements, such as China used this lamp tin plate made of kerosene, shaped like a horse, so called "tin".
Q:Tin plated tin plated?
Can electroplate.If the parts need tin plating, it is better not to use tinplate (tin plated steel / strip), galvanized steel plate / ordinary steel plate / strip with or without plating.
Q:Why do tin tins rust easily when they are opened?
The tinplate is of poor quality and the tin is not enough
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:What details should I pay attention to when purchasing tinplate packing boxes?
Many small processing plants or small factories can accept the buyer's bargaining, but the iron is really not flattering. In fact, the market is very transparent iron materials, buyers do not mean that the more the better the bargaining, but to understand the market, do not bargain.
Q:Who knows the process of tinplate production?
Cold rolling: the hot rolled strip passes through the pickling process and enters the cold rolling process. The strip is plastically deformed during the work roll, and the thickness is about 2mm.2mm from about 0. In cold rolling, in order to reduce the friction between the strip and the work roll and take away a large amount of heat produced by the plastic deformation, the cold rolling lubricant and coolant should be sprayed onto the strip. A reversible mill with single stand is adopted. In order to keep the shape of the roller effectively, the temperature control of the cooling liquid is more important. Range of production: 0.14mm-0.5mm.Slitting: the required width of slitting material after cold rolling. Range of production: 265mm-835mmSkim: in the cold rolling process in rolling oil cooling after tin plate surface adhesion of oil and other foreign matter, such as do not wash directly by annealing the oil incomplete combustion of carbonaceous residue will stain in the strip, for the production of tinplate can meet the quality requirements. Therefore, the tin plate must be cleaned by electrolysis before removing the grease. The common method of cleaning tin plate is to degrease and degrease the degreasing liquid.
Q:Should vacuum filling be required for tinplate meat filling?
Mainly depends on your production process needs
Q:How to quickly distinguish tinplate and ordinary substrate iron?
Tinplate is the substrate, iron tin plating, tin bright, the substrate is dark, the substrate for a few days rust, and the two put together, the difference is great.
Q:What's the head iron?
SPTE, which is commonly known as tin, tin plate, thickness of 0.15-0.3mm, width, generally between 300-900mm.
Q:What are the differences in the corrosion behavior of two ferrous iron products?
Tinplate is a tin covered with tin, it is not easy to rust, also known as tin iron. This kind of galvanized steel in a long time Chinese called "tin", some people think that the tin plate cans was made from the Guangdong province of Macao (English Macao readable if imported, tin) so called "tin".
