1.Structure of Tinplate (ETP) Coil and 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 Tinplate (ETP) Coil and 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: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 many kinds of tinplate are there? What is the code number?
Specification: Tinplate tinplate cans (three cans) is mainly divided into "15120", "15173", "15240" etc.. "15120" capacity is 2.2kg, diameter is 150.3, height is 120; "15173" capacity is 3kg, diameter is 150, height 173; "15240" capacity is 4.5kg, diameter is 150, height is 240.
Q:Why do tin tins rust easily when they are opened?
Tin iron loses electrons and gets an electron redox reaction to accelerate the corrosion process
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:Who can tell me how to adjust the roller seal defects?
In the sealing device, the roll sealing roller, the upper pressure head tray, usually referred to as sealing three elements. The correct groove shape of the roller, the reasonable position of the head and the proper driving force of the tray support are the necessary conditions to ensure the normal roll sealing. (see Fig. 1) it is easy to see that the three elements of the seal are the basic components of the sealing device and are also a fundamental factor affecting the double hemming.
Q:Tin can bake oven electrical electromagnetic induction principle
If it is not sealed, it is said to be heated and then changed after being heated.
Q:What is the process of two cold rolling of tinplate?
Tin plays a major role in preventing corrosion and rusting. It will be the steel strength and formability and corrosion resistance of tin soldering, and beautiful appearance with a material, corrosion resistant, non-toxic, high strength and good ductility properties.
Q:How big is the difference between tinplate and stainless steel 316L?
316L is a kind of austenitic stainless steel with excellent corrosion resistance. The tinplate is not comparable. 316L is superior to tinplate in appearance, corrosion resistance, heat resistance and strength. Of course, the price is much higher than that of tinplate.
Q:How to distinguish galvanized plate and tin plate
General galvanized sheet used in home appliances and electronics industry, thicker. Tin plate, tinplate, used in packaging industry, thinner.
Q:What's the advantage of metal containers in packing tea?
General metal cans are divided into three kinds of tinplate (also known as: tin iron) tin cans, aluminum cans
