What material can be used for hollow blow molding machine
The plastic varieties used in the hollow blow molding machine include polyethylene, polyvinyl chloride, polypropylene, polystyrene, linear polyester, polycarbonate, polyamide, cellulose acetate and polyacetal resin. Among them, the consumption of high-density polyethylene occupies the first place. It is widely used in food, chemical and liquid processing packaging. 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 because of its better transparency and air tightness. With the development of non-toxic polyvinyl chloride resins and additives, as well as the development of stretch blow molding technology, the amount of polyvinyl chloride containers used in food packaging has increased rapidly, and they have begun to be used for packaging of beer and other carbon dioxide-containing beverages. . Linear polyester material is a new type of material that has entered the field of blow molding machines in recent years. Because its products have the advantages of glossy appearance, excellent transparency, high mechanical strength and good preservation of the contents of the container, and the advantages of not polluting the environment during waste incineration, it has developed rapidly in packaging bottles, especially It is most widely used in pressure-resistant plastic food containers. Due to the modification of its resin and the progress of processing technology, the use of polypropylene has also increased year by year.
