What materials can be used in Chinese blow moulding machines

The plastics used in Chinese extrusion blow molding machine are polyethylene, polyvinyl chloride, polypropylene, polystyrene, linear polyester, polycarbonate, polyamide, cellulose acetate and polyacetal resins. Among them, the consumption of high-density polyethylene is the first. It is widely used in the packaging of food, chemical and process liquids. High molecular weight polyethylene is suitable for the manufacture of large fuel tanks and barrels. Polyvinyl chloride is widely used in the packaging of cosmetics and detergents because of its good transparency and air tightness.

With the development of non-toxic polyvinyl chloride resins and auxiliaries, as well as the development of stretch blow molding technology, the use of polyvinyl chloride containers in food packaging has increased rapidly and has begun to be used in beer and other beverages containing carbon dioxide gas beverages. . Linear polyester materials are new materials that have entered the field of blow molding in recent years. Due to its glossy appearance, excellent transparency, high mechanical strength and good preservation of the contents of the container, the waste incineration treatment does not pollute the environment, so the development of the bottle is very fast, especially It is the most widely used in pressure-resistant plastic food containers. Due to the improvement of its resin modification and processing technology, the use of polypropylene has also increased year by year.
