tinplate

With the the tinplate variety of CC material, the DR materials, plated ferrochrome and constantly enrich and promote the packaging products and technology development, metal packaging is full of innovation.

        With the continuous improvement of people's consumption level, food packaging requirements are also increasing. Variety of food packaging materials, metals, wood, plastic, paper, bamboo material. In metal packaging, again tinplate packaging based. Tinplate printing technology and processing technology continues to improve and perfect, the tinplate packaging more widely. Market share rapidly increased year by year development trend, and continuous development of tinplate packaging as packaging manufacturers and packaging design of the primary task of the workers.

      1. tin tin is plated with a layer of tin metal, it is not easy to rust, also known as tin-plated iron. The iron plates dipped into the molten liquid tin obtained. Tin is a reactive metal than iron, neither oxidized by air without reacting with water, so there are very strong corrosion resistance. The iron plates coated a thin layer of tin can be a good protection. Coating once destroyed electrochemical corrosion occurs because iron is more lively than tin, iron will as the original battery's negative oxidation loss, the presence of tin will accelerate the corrosion rate of iron, tin and tin, it can only only in the case of coating intact to protect the role of iron.

Do canned tin, covered in shiny silver, is very beautiful. This is because the dip of the light of tin, tin gown to wear in the metal outside, people called this metal as a "tin". About the origins of the "tin" the old name, is said to be the past, foreign businessmen from China's Tibet Ali horses mouth input, this metal; that due to our past to do with this metal kerosene lamps, the lamp, shaped like a horse mouth, so hereinafter referred to as "tin". Tin in the world annual production of almost 30% is used to make tinplate.

      At present, the production oftinplate in the international arena for the production of packaging containers, a special need. The original production of tinplate not take into account the special requirements of packaging container manufacturing, just ordinary tin, so the production of packaging supplies and more inappropriate. In the development and production of special packaging tin, Europe, walking in the forefront of the world. French Iron and Steel Group is Europe's largest iron and steel enterprises, the quality and yield are not inferior to Japan, while the improvement of production techniques and varieties of Japan than. In recent years, the French steel company first developed special packaging tin, and put into the market, causing a revolution in the packaging industry.

        Tin canned food, with the exception of a small number of light colored fruit and canned fruit juices, most of the internal painting of cans, in order to improve the corrosion characteristics of thecontainer; due to the electrochemical effect of the metal, paint cans, canned food storage there will be a small amount ofthe dissolution of the iron, the form of divalent iron to seal canned food,can easily be absorbed by the body content of about 1 to 10 ppm. The iron content of the raw material itself is not much, fruit and vegetable products, cans product per can of 350 ml ofbeverage cans, the iron content of 5 ppm, and each tank can be 1.75mg iron, about the human daily intake of 18mg the tenth. The above fruit and vegetable juice beverage cans are rich invitamin C, iron more easily absorbed, and therefore more far-reaching iron canned food and beverage may well be a good source of iron, tin cans of food to provide nutrition.
