After reading these, do you dare to say that you understand tinplate?
Tinplate is a tin plate coated with tin on the surface. It is not easy to rust, also called tinplate. Tin mainly acts to prevent corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability and aesthetic appearance of tin in a material with corrosion resistance, non-toxicity, high strength and good ductility. This kind of coated steel plate has been called "tinplate" for a long time in China. Some people think that because the tin-plated sheet for canning at that time was imported from Macao, Guangdong Province (English name Macao can be read as Makou), it is called "tinplate". There are also other claims. For example, in the past, China used this tin-plated sheet to make the head of a kerosene lamp, which is called a tinplate. The name "Tandil" is not exact. Therefore, in 1973, the Chinese tin-plated sheet meeting was called the tin-plated sheet, and the official name no longer used the name "tinplate."
Tinplate is a metal container packaging material. The tinplate packaging container has many advantages such as high strength, good formability and strong compatibility with products. It has established a good reputation in the international market. In addition to these, it also has good sealing, preservation, light protection and firmness. In addition to causing adverse reactions in food, light can also cause changes in proteins and amino acids. However, when vitamin C is exposed to light, it is more likely to cause it to interact with other food ingredients, resulting in a large loss. According to research and analysis, the loss of vitamin C in milk in clear glass bottles is 14 times higher than that in dark bottled milk. It also causes oxidation and odor of milk, as well as cracking of nuclide and methionine, which loses nutritional value. The opacity of the tin can makes the preservation rate of vitamin C the highest. The application of tinplate is very wide. From the packaging materials for food and beverages to grease cans, chemical cans and other miscellaneous cans, the advantages and characteristics of tinplate provide physical and chemical protection of the contents.
Tinplate packaging containers are well received by customers and are widely used in food packaging, pharmaceutical packaging, daily necessities packaging, instrumentation packaging, industrial packaging, and pesticide packaging. It includes: food cans, beverage cans, chemical cans, spray cans, dry cans, grease cans, etc. Tinplate printing is also a physical property that uses water and ink to repudiate. With the printing pressure, the printing plate is transferred to the tinplate by the blanket, which belongs to the principle of lithographic offset printing. Due to the special physical and chemical properties of tinplate and the reworkability of printed matter, the printing process is quite different from ordinary offset printing. Especially in the pesticide industry, there are strict requirements on the traceability code of pesticide electronic label on tinplate. In other industries, the code can be placed on the bottom of the bottle and the cap (pull ring), but it is required by the Ministry of Agriculture of the pesticide industry. The code must be placed on the electronic label of the bottle. In other locations, the manufacturer must apply to the Ministry of Agriculture for further coding. If you want to solve the product on-line, you need to use professional coding equipment.
YOUGAOMARK 1 tin can marking system is suitable for all tinplate, chrome-plated iron and aluminum skin paging, code, data collection, verification, non-conforming products after testing, and qualified products collection. The key point is that it can directly mark the trace number of the pesticide electronic label on the electronic label of the bottle after completing the bottle spray pattern in the pesticide industry with special requirements, and complete the product code, data collection check and test. Unqualified rejection and collection of qualified products. Greatly save a lot of unnecessary troubles and additional cost of coding, which provides more convenience for production.
Tinplate cans meet the requirements of environmental protection packaging. Existing containers include iron cans, aluminum cans, papers and plastic containers. The recycling characteristics of these containers vary, but the recycling of iron cans is better than that of other packaging materials. excellent. Based on the international environmental management standard ISO-14000, the tinplate cans with low pollution, recyclability and resource-saving characteristics will have wider development space in future packaging applications:
1. Low pollution: The main raw material tinplate in the iron can container is in fact environmentally friendly and can be naturally decomposed, because when the iron can exists in the environment, it can naturally oxidize and return to the original iron oxide state, returning to nature. Therefore, the stacking of scrap cans can be decomposed by time and will not cause environmental pollution. At the same time, it is not necessary to cut down trees to make iron cans, and it will not destroy the ecological balance.
2, recyclable: The iron can itself has a characteristic that other packaging materials do not have - can be adsorbed by the magnet, so that the magnetic separator can be used to separate the iron can from the waste by magnetic force, and this feature can be utilized. Easily achieve the effect of recycling 80% of the cans in the garbage. The invention of environmental protection cover not only makes the use of iron cans safer and healthier, but also effectively reduces the amount of garbage, and has direct and obvious benefits for recycling operations.
3. Provincial resources: In the removal of other polluting residues on iron cans, shredder equipment has been developed to effectively remove more than 98% of the pollutants and provide good quality iron scraps. In addition, the United States also pointed out that the presence of aluminum easy-opening is conducive to scrap iron re-production because it can reduce the amount of Hot Metal used in steelmaking and reduce the cost of overall steel manufacturing. In addition, in terms of energy conservation, the report pointed out that the use of tinplate waste to produce steel can save 230m3 of natural gas per ton of scrap iron scrap compared to iron ore production, so the recycling process of tin can reduce the global environment. With the impact of energy, it is in line with future product trends.
In 2010, the sales revenue of metal packaging containers in China exceeded 50 billion yuan, which also made metal packaging enter a new period of growth opportunities. The sustained and rapid development of the food industry has brought a broad market development space for the tinplate packaging container industry.
