• What is tinplate?
• Tinned steel sheet referred to as tinplate, commonly known as tinplate, is a product made of tinning on a thin mild steel plate. The tin plate produced by the hot dip process is called the hot dip tin plate, and the tin plate produced by the electroplating process is called the electroplated tin plate.
• Because about 98~99.8% of the weight of the tin plate is steel, it is a coated steel variety that belongs to metallurgical products.
We are the professional manufacturer in China with advanced technical equipments, first class inspection devices and substantial experience in production. It possesses integrated process lines including smelting, hot rolling, cold rolling and coating. The product catalogue covers ETP and TFS with an annual output over 1 million tons. Our tin mill products are widely sold and used throughout the world in application of packaging of food, beverage and industrial goods and enjoy high reputation in the international market.

• The characteristics of the tin plate are largely determined by the characteristics of the tin.
• Tin is a silver-white metal with a light blue color, atomic weight 118.7, specific gravity 7.28, melting point 2320C in the atmosphere does not change color, chemical properties are also very stable. The tin plate can keep the metallic luster of the tin for a long time.
• Tin is a soft metal, so when tin plates are processed to make cans, the tin layer will not crack and fall off.
• Tin compounds are non-toxic, and when a small amount of tin is dissolved in food, it has no adverse effects on the color, taste, nutritional value of food and human health.
• Tin has good brazing properties, so the steel plate is easy to solder after tin plating, and it is easy to process when tin plates are used to make cans and other containers.
• The shape of the tin plate is smooth and bright like a mirror, and it is easy to paint and print.

| The hardness is the average value of 2 samples, allowing 1 of them to exceed the specified allowable range by 1 unit. | |||||
| a The yield strength is a reference value determined as required. b Yield strength is the average value of the two samples. The sample is P5 in GB/T 228, and the direction of the sample is transverse. c Due to the thickness thinning effect, the elongation is too low and the yield strength cannot be measured. In this case, the yield strength is replaced by the tensile strength. d For the tensile test, the width of the parallel part of the sample is (12.5±1) mm, and the standard distance L0=50mm. Before the test. The sample should be artificially aged for 20min at 200℃. | |||||

5. Usage Precautions for ETP
Modern industrial tinplate is usually a cold-rolled, low carbon sheet coated with commercial pure tin on both sides, which combines the strength and formability of steel with the corrosion resistance, weldability and appearance of tin. Tinplate is widely used in the food industry and a variety of containers, stamped products, packaging materials for non-food industry, such as food cans, spray cans, bottle caps, gas containing beverage cans, packaging materials and non-packaging materials (home appliances, toys, stationery, engineering).
Beverage Tinplate Can
We specialize in manufacturing beverage tinplate can in China, and the tinplate can is used for packing beverage like juice, coffee, tea, sports drink, cola, soft drink, and beer, etc. The beverage tinplate can is available in various specifications, tall and short, big and small, round and square, and others, for instance, to meet diversified needs for beverage packaging.
As we know, air and volatile gas barrier property and preservation of nutrition and organoleptic quality is essential for packaging containers. By comparing a variety of juice packaging containers, we see that the oxygen transmission rate of containers directly affects juice browning and vitamin C conservation. Among low transmission rate containers such as metal cans, glass bottles, and cartons, the beverage tinplate can provides the best protection for vitamin C.
The tin inside tinplate reacts with the residual oxygen in the container, thus reducing the chance of food oxidation. Tin reduction contributes to desirable protection for light color fruits, juice flavor and color. Hence, the beverage tinplate can with no paints boasts superior preservation to that of other packaging materials, with slighter browning, higher flavor acceptability, and longer shelf life of the contained juice.
Offers coils and sheets, coil packed in a vertical form or a horizontal.
A label that indicates the manufacturing history is affixed to the outside of the packaging. In addition, a service card is contained inside.
