[The origin of the name of tinplate] Tinplate was called Tin Plate in the early days, and its official name should be Tin Plate. Because China's first batch of foreign iron was imported from Macau in the middle of the Qing Dynasty, Macau was transliterated "horse mouth" at that time, so it is generally called "tinplate". Tinplate has 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 protection of the contents in terms of physical and chemical properties. Packaging materials for tinplate cans that meet environmental protection requirements: Existing containers include iron cans, aluminum cans, paper and plastic containers. The recycling characteristics of these containers are different, but the recycling treatment of tin cans is better than other packaging materials. . Based on the implementation of the international environmental management standard ISO-14000, tinplate cans with low pollution, recyclability and resource saving characteristics will have a broader development space for future packaging applications. https://c2.staticflickr.com/2/1773/43241618164_bc5e6b2443_h.jpg ※Please pay attention when you place an order!
