        Tin originated in Bohemia (now Czech Republic and Slovakia). Since ancient times the land rich in metals, advanced technology, and know how to use water in the machine, from the 14th century began to produce tin. Generally in a very long period of time, there has been a major producer of tin in the world. Tinplate was the main tool used to make cutlery and drinking.

               Existing containers including cans, aluminum cans, paper and plastic containers, the recycling of these containers have different characteristics, but the cans in the recycling container than other packaging materials for the gifted. Based on the international environmental management standard ISO-14000 will be implemented soon, with low pollution, recycling, resource saving features of tin cans, packaging purposes in the future, there will be a broader space for development: 1 clean: tin container main raw material tin, in fact, part of the environmental soundness, biodegradable, because when the tin in the environment, can be naturally oxidized iron back to the original state, return to nature, so the scrap pile is by the time the tank decomposition, and will not cause environmental pollution remaining. At the same time making cans do not have to cut down trees, will not damage the ecological balance. (2) recycled: tin itself would have an other packaging materials that are not characteristic ─ adsorption can be magnets, so you can rely on the use of magnetic separator to separate the tin from the waste, the use of this feature easy to achieve 80% recycling trash cans results. The green cover of the invention, the use of cans not only safer, health, and reduce the amount of waste, the recycling operations have a direct and obvious benefits. 3 Province resources: pollution in the removal of tin residues on the other side, has developed a shredding machine equipment, can effectively remove 98% of the pollutants, provide good quality scrap metal debris. In addition the United States also pointed out that the presence of aluminum easy-open lid and then the system will help scrap metal because it can reduce the amount of steel at Hot Metal, reduce the overall cost of manufacturing steel. Besides saving energy, the report pointed out that the use of tinplate steel litter production of iron ore production compared ton scrap metal scrap can save about 230m3 of natural gas usage, so the steel cans and recycling system process can reduce the global environmental and the impact of energy to meet future product trends.

Chrome-plated iron

          Thin steel plate that Wuxi, China since been extended to 80 years, has been in a wandering state, until after 2000, only to be universally applied, even in this year there will be tin-plated iron ferrochrome expensive than the price situation, the reason is plated with chromium in Indian iron coating process is superior to tinned iron. With the widespread use of iron paint, especially in the cap, the more chromium-plated by the people's attention, and chromium plating is characterized by: (1) processing and canning substrate corrosion resistance of the substrate with the same tin; (2) coating process, the need to consider issues such as tin tin melting, higher baking temperature can be used to improve the efficiency of printed and coated production; (3) the adhesion of the coating, superior to tin; (4) the surface is a layer of thin layer of chromium and hydrated chromium oxide layer, the thickness of tin layer of about 1% tin. So easy to rust. So, without coating process, there is no chrome-plated practical value. (5) because it is Wuxi sheet, so save the tin resources in line with the development direction of tinplate.
