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 cans comply with environmental protection packaging materials: existing containers include iron cans, aluminum cans, paper and plastic containers. These containers have different recycling characteristics, but the iron cans are better in recycling than other packaging materials. .
