Today we are going to introduce the raw material tinplate, which is the common name for electroplated tin steel sheet. The English abbreviation is SPTE, which means plating on both sides. Cold rolled low carbon steel sheet or strip with commercial pure tin. It combines the strength and formability of steel with the corrosion resistance, solderability and aesthetic appearance of tin in a material. It has the characteristics of corrosion resistance, non-toxicity, high strength and good ductility. It is widely used in food. , beverages, grease, chemicals, paints, paints, sprays, bottle caps and many other daily necessities.


       The British invented the first tinplate cans for food and long-term preservation in 1800, but the tinplate was produced by hot dip tin; after the 1820s, the tinplate was very large in the United States. The development of the demand and the increasing demand, in 1847 the United States invented the can machine, and gradually replaced the manual cans; the invention of the electric welder in 1900 made the tinplate canning efficiency greatly improved, and because of the high price of tin, people gradually Tinplate is produced by electroplating tin; after the 1990s, canning technology has developed rapidly, and high-speed welders can reach production levels of 1000 cans per minute. From the mid-20th century, chrome-plated steel sheets were introduced to replace some of the tinplate products.


      At present, the development trend of tinplate for packaging is to reduce the thickness of materials and improve the mechanical properties of materials. In the packaging industry, the use of tinplate covers a large proportion.
