Product Description

Tinplate, an alloy of tin (Sn) and iron (Fe), where Sn is the coating, tinplate is also called tin-plated iron

Tinplate is the common name for electroplated tin-plated thin steel plates, and its English abbreviation is SPTE. It refers to cold-rolled low-carbon thin steel plates or steel strips plated with commercial pure tin on both sides. Tin mainly prevents corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and beautiful appearance of tin into one material. It has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility.

2. Substrate thinning: This is a well-known wish. Currently, 0.15m/m tinplate is used for lid production in my country. Some cold-rolled plate companies have announced that they can produce 0.12m/m cold-rolled plates for the cover industry. Therefore, secondary cold-rolled tinplate with thinned substrate and enhanced hardness is the development direction of the can (lid) industry.

The list of tempering degrees of tinplate in the world is as follows:
Secondary cold rolled tinplate:
Traditional Symbol Current Symbol HR30T Value Tensile Strength (MPA) Purpose
DR8DR55073550+70 round can body, bottom and lid
DR9DR62076620+70 round can body, bottom and lid
DR9MDR66077660+70 Beer and carbonated beverage can bottoms and lids


Primary cold rolled tinplate:

T1 T50 52 330 extremely harsh deep drawing

T2 T52 52 350 deep drawing

T2.5 T55 55 general use

T3 T57 57 370 is for general use, the can body is not scratched

T4 T61 61 415 is generally used. It is relatively rigid and requires rigid bottoms, lids, shallow flush tanks, etc.

T5 T65 65 450 anti-warping, requires rigid bottom, lid and can body

T6 T70 70 530 is very rigid, used for the bottom and lid of beer and carbonated beverage cans

For the same can type, secondary cold-rolled tinplate can be used to replace thicker with thinner to improve the utilization rate of tinplate

Our Advantages

1.Opacity

In addition to causing deterioration reactions in food, light can also cause changes in proteins and amino acids. Vitamin C is more likely to interact with other food ingredients when exposed to light, resulting in a large amount of loss. According to research and analysis, the loss of vitamin C in milk in transparent glass bottles is 14 times higher than that in milk in dark bottles. Light will also cause the milk to produce oxidized odor, as well as cleavage of nuclides, methionine, etc., resulting in loss of nutritional value. The opacity of tinplate cans gives the highest preservation rate of vitamin C.

2.Good sealing

The barrier properties of packaging containers against air and other volatile gases are very important for the preservation of nutritional content and sensory quality. Comparing various juice packaging containers proves that the oxygen permeability of the container directly affects the browning of the juice and the preservation of vitamin C; metal cans, glass bottles, aluminum foil glue laminates, and cartons with low oxygen permeability affect the preservation of vitamin C. is better, among which the iron can is the best.

3. Reduction of tin

The tin on the inner wall of the tinplate will interact with the oxygen remaining in the container during filling, reducing the chance of food ingredients being oxidized. The reducing effect of tin has a good preservation effect on the flavor and color of light-colored fruits and juices. Therefore, juice cans packed in unpainted iron cans have better nutritional preservation than juice cans packed in other packaging materials, and the browning is lighter. The flavor quality is better accepted and the storage life is extended.

4. Provide a source of effective iron

Tinplate canned foods, except for a few light-colored fruit and juice cans, mostly use empty cans that are painted inside to improve the corrosion resistance of the container. Due to the electrochemical effect of the metal, there will be a small amount of canned food in painted cans during storage. The iron is leached out and exists in the form of divalent iron in sealed canned foods. It is easily absorbed by the human body and the content is about 1 to 10 ppm. For fruit and vegetable products, the raw materials themselves do not contain much iron. Iron canned products are calculated based on the iron content of 5ppm per can of a 350ml beverage can. Each can can provide 1.75mg of iron, which is about ten times the human daily intake of 18mg. one part. If the above-mentioned fruit and vegetable juice beverage cans are rich in vitamin C, iron can be more easily absorbed, so iron canned food and beverages can be regarded as a good source of iron, and the nutritional significance of tin canned food is even more profound.

Because of these properties, tinplate cans provide a closed system that is completely isolated from environmental factors except heat. It prevents food from deteriorating due to light, oxygen, and moisture, and does not become dilute due to the penetration of aroma or be affected by environmental odors. The food storage stability is better than other packaging materials. It has the highest preservation rate of vitamin C and the best preservation of nutrients.

Product Application

Tinplate is used in a wide range of applications, from packaging materials for food and beverages to grease cans, chemical cans and other miscellaneous cans. The advantages and characteristics of tinplate provide good physical and chemical protection of the contents.

1. Canned food

Tinplate can ensure food hygiene, minimize the possibility of spoilage, and effectively prevent health risks. It also meets modern people's needs for convenience and speed in eating.

2. Beverage cans

Tinplate cans can be used to fill juice, coffee, tea and sports drinks, as well as cola, soda, beer and other beverages. The highly workable nature of tinplate cans allows for a wide variety of can shapes, whether tall, short, large, small, square or round, to meet the diverse needs of today's beverage packaging and consumer preferences.

3. Grease tank

Light will trigger and accelerate the oxidation reaction of oils, reduce the nutritional value, and may also produce harmful substances. More seriously, it will destroy oily vitamins, especially vitamin D and vitamin A.

The oxygen in the air promotes the oxidation of food oils, reduces protein biomass, and destroys vitamins. The opacity and air-sealing isolation effect of tinplate are the best choice for packaging oily foods.

4.Chemical tanks

Tinplate is strong, protective, non-deformable, shock-resistant and fire-resistant, making it the best packaging material for chemicals.

5. Spray and other miscellaneous cans

Tinplate cans that can withstand high temperature and high pressure, especially suitable for high-pressure filling spray cans. Biscuit barrels, stationery boxes and milk powder cans with various shapes and beautifully printed shapes are all tinplate products.
