What materials can be used for hollow blow molding machines

The plastic varieties used for hollow blow molding machines include polyethylene, polyvinyl chloride, polypropylene, polystyrene, linear polyester, polycarbonate, polyamide, cellulose acetate, and acetal resin. The consumption of high-density polyethylene ranks first among them. It is widely used in packaging for food, chemical, and liquid processing. High molecular weight polyethylene is suitable for manufacturing large fuel tanks and barrels.

Polyvinyl chloride is widely used in the packaging of cosmetics and detergents due to its good transparency and airtightness. With the development of non-toxic polyvinyl chloride resin and additives, as well as the development of stretch blow molding technology, the usage of polyvinyl chloride containers in food packaging has rapidly increased, and they have begun to be used in the packaging of beer and other beverages containing carbon dioxide gas. Linear polyester material is a new type of material that has entered the field of hollow blow molding machines in recent years. Due to its advantages such as glossy appearance, excellent transparency, high mechanical strength, good preservation of items inside the container, and no environmental pollution during waste incineration, its products have developed rapidly in the field of packaging bottles, especially in the use of pressure resistant plastic food containers. Due to the modification of its resin and the advancement of processing technology, the usage of polypropylene has also increased year by year.
