The main raw material for the production of plastic barrels is polyethylene (PE), which is a high molecular organic compound formed by addition polymerization of ethylene. Polyethylene is recognized as the best food contact material in the world, non-toxic, tasteless and odorless, and meets the hygiene standards for food packaging. Polyethylene film, light and transparent, has the properties of moisture resistance, oxygen resistance, acid resistance, alkali resistance, general air tightness, and excellent heat sealability. Material. Secondary water supply in high-rise buildings, water storage, water treatment, medicine and food, electronic chemical industry, aquaculture, textile printing and dyeing, petrochemical reagents, pickling and electroplating, brewing sugar, vegetable pickling, refrigeration, environmental protection and hygiene and other industries widely used in.
metal pails are larger capacity containers made of sheet metal. Its specifications include small open head pails, middle open head barrels, carrying barrels, special-shaped top barrels, full-opening conical steel barrels, full-opening barrels, straight-opening barrels, opening necked steel barrels, and so on. It has a very wide range of applications, involving many industries such as food, beverage, chemical, aerosol and other content packaging. In order to meet the needs of these packagings, metal drums have various properties suitable for them, among which the sealing properties are common and very important. Compared with other packaging materials, metal materials are denser, stronger, easier to form and process, and metal drums have better sealing performance, which can be suitable for long-term storage of food and items that meet high requirements such as leak-proof, anti-corrosion, and pressure resistance. , because the application field of metal barrels is very wide and has an irreplaceable status.
