1.Structure of Electrolytic Tinplate 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 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.

5.FAQ of Electrolytic Tinplate for Foods and Chemical Packaging
- How are the Electrolytic Tin Plates specified?
The Electrolytic Tin Plates are specified as per the steel base, extent of tempering, the coating weight, annealing method and the surface finish.
- How many types there are for base steels?
The base steels are of three types: Type MR, L, D
- Q:A tin rust problem for help
- Once the outer rust rust, if the area is not large, can use sandpaper to rub the rust, and then wipe clean towel can surface, then coated with a layer of antirust oil; if the outer rust area of about 1/2, we must take into account whether the corrosion to the inner wall, has affected the quality of the contents. If rust occurs on the inside, you need to remove all the rework, tank canning, liquid injection, degassing, sealing and sterilization, cooling, after 2 times of high temperature sterilization of canned products, generally need to downgrade, or if some products in the two sterilization will appear after taste and color changes, you need to direct rejection.
- Q:Can you tell me how to deal with the recycling of tinplate?
- General tinplate packaging waste, as long as the rust is not serious, can be converted into hardware products, to achieve the best use of materials. The consumption of tinplate in our country is relatively large (600 thousand tons / year), and 125 tons of tin packing waste can be recovered 1 tons of tin.
- 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:How to distinguish galvanized plate and tin plate
- From the outside, hot galvanized, electro galvanized tin plate surface is rough, thick tin layer of light and bright, thin tin layer, hot galvanized galvanized is not only the contest, Matt
- 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:How many kinds of tinplate are there? What is the code number?
- 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 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". The name "tinplate" is not exact. Therefore, in 1973, when the Chinese tin plate meeting was called "tinplate", the official document no longer used the name "tinplate".
- Q:How can recycled tin cans be recycled?
- The broken material is separated by the air whirling sorting system, and the metal and nonmetal are separated from each other. Moreover, the whole system is equipped with a dust removing device to minimize the damage caused by dust pollution in the process of production.Tin tins, crushing machines, equipment and maintenance costs are low: equipment design is reasonable, well made, extending the service life of equipment, reducing the use and maintenance costs of equipment.
- Q:How do you clean the dust and trace oil on tin containers?
- Water based cleaning method: that is, with clean water and cleaning agent to remove oil method, the use of water washing process. This process started relatively late in the country, and the technical strength of various manufacturers formula is uneven, of which the more representative of public praise is "evergreen peak" brand CLF water-based cleaning agent series.
- Q:How do you paint the tinplate?
- Chemical stores have sold, elegant light paint, paint and other various patterns. Don't brush, a keg of a nozzle is put it.
- Q:Why do tin tins rust easily when they are opened?
- The tinplate is of poor quality and the tin is not enough
