Product Description:

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.

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:What's the latest price for tinplate?
Now private factories can be produced, the thinnest can be produced to 0.14MM, the most thick can be 0.6MM. Tin can be plated with different thickness. The hardness of DR8, DR9, T1 these private tinplate factory can reach
Q:What is the difference between Maguchi Tetsu tinplate and galvanized board
Tin plated steel sheet and strip, also known as tinplate, the steel plate (belt) surface tin plated, has good corrosion resistance, non-toxic, can be used as packaging material cans, inside and outside the cable sheath, telecommunications instrument parts, flashlight and other hardware.
Q:What is the use of tinplate printing tin, storage of food safety
Electrophoresis on a layer of special coating with food packaging, the packaging is extremely tight, in order to packaging material appearance, appearance are printed with various patterns, because it is the coating of food grade materials, so the food packaging is safe in the warranty period.
Q:Advantages and disadvantages of tinplate packaging
Characteristics and advantages of the 1. materials can tinplate opaque sealed 3. tin 2. good reduction of 4. provides a source of effective iron 5. Recyclable, reuse. In compliance with international environmental requirements, in line with the future trend of the 6. products is strong, good protection, no deformation, shock resistance, fire resistance, resistance to high temperature and high pressure
Q:And what are the main packing materials?
Currently on the market and it is mainly two kinds of packaging: PET plastic bottles and cans cans of Maguchi Tetsumi.Pet Chinese means: polybutylene terephthalate mainly consists of polyethylene terephthalate, two ester PET and polybutylene terephthalate Ding Erzhi PBT. Polyethylene terephthalate is also commonly known as polyester resin, commonly known as polyester resin. It is a condensation of terephthalic acid with ethylene glycol and is collectively referred to as thermoplastic polyester, or saturated polyester, with PBT.
Q:How to quickly open the bottle?
Put the tins of canned fruits soaked in hot water for 3-5 minutes, so that the tank gas temperature rises, the pressure is increased, which is the principle of expansion and contraction. Turn the canned fruit bottle upside down for a while. When the liquid in it breaks down the vacuum inside and outside, tap it in the bottom with your palm and pull it gently. It's easy to pull apart.
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:Why tin tin plating?
In nature, tin is seldom free, so there are few pure metallic tin. The most important tin ore is cassiterite, chemical composition of two tin oxide. This copper smelting tin, iron, aluminum is easy, as long as the cassiterite together with burning charcoal, charcoal will be put out in cassiterite tin reduction. Obviously, the ancient people tin place if there is fire burning when grilled wild animals, the earth would be charcoal reduction of cassiterite, tin silver and melted will flow out. Because of this, tin was discovered long ago.
Q:What kind of metal material is tinplate? How much is the current price per ton?
Tinplate originated in Bohemia (now Czech and Slovakia). The land has been rich in metal technology since ancient times, and know how to use water power in the manufacture of machinery, from fourteenth Century onwards began to produce tinplate. For a long, long time, it has been the main source of tinplate in the world. Tin was mainly used for making tableware and drinking utensils.
