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:How many kinds of tinplate are there? What is the code number?
Tinplate, also known as tin plated iron, is the common name for tin plated steel sheet. The English abbreviation is SPTE. It is a cold-rolled low carbon steel sheet or strip coated with commercially pure tin on both sides. 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 to test the tightness of tin metal cans?
A careful observation of empty tank tank bottom edge and welding seam has no air bubbles, where the same parts of continuous bubbles, should be judged as leakage, leakage of the recording time and vacuum degree, and make a mark in the leak site.
Q:Tinplate why have white and yellow, tin plating should be white ah, yellow is how to return a responsibility?
Tinplate itself is no color, it is iron color.
Q:Who can tell me how to adjust the roller seal defects?
The sealing process of hxa tank by double seam operation completed. Double seam method refers to two different groove shape of seaming rolls, through two feed motion sequence, the tank body and the tank cover with lid, crochet and cans, flanging hook tightly, so as to achieve the purpose of sealing method. Simply, that is the first edge hook, two edge compression molding.
Q:How do you clean the dust and trace oil on tin containers?
Solvent cleaning: This is the traditional way, from the middle of the Qing Dynasty period have been used, it is with a cleaning agent such as solvent, steam coal, white oil (to waterlogging, water purifier, hydrocarbon and so on).
Q:Can tinplate be shielded?
For tinplate shielding, it is a kind of shielding material, at present 3 applications more cheap, processing is good, but the finished long-term placement of rust on the fracture surface, thus affecting the weldability, which is its only drawback. If it is placed in a short time, it will not affect weldability. Electroplating is not the best way to solve the problem. My supplier is coated with an anti rust paint on the fracture surface, and then ultrasonic cleaning is done before going on line. But I mostly use "ocean shield frame copper to make," a little expensive, but the performance is very good ^_^
Q:Tin can weldingHow can the side of the column of the pop top be welded or pressed?,
Mainly divided into the tank, the tank cover and the tank bottom three parts. The tank body is made of a piece of iron material through the curl bending machine, by using copper welder and welding. Now the mainstream of aerosol cans, food cans and beverage cans are produced by this method.
Q:What is tin plate?
In acid environment, tin protection layer of tinplate is contacted with the outside directly. Because tin is corroded slowly, it can protect the substrate. If the tin protection layer has pinholes, cracks and other defects, it will expose some of the matrix, resulting in corrosion of the matrix.
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:What are the causes of tinplate rusting and how to prevent them?
The tin surface of the iron sheet is injured and exposed during the machining process to promote corrosion.Prevention: 1, not coated iron sheet, coated with oil after plating thickening. Effectively prevent water invasion and reduce damage to the process.2 can be painted on the iron sheet of appropriate paint, blocking the impact of corrosive substances.
