What are the types of plastics used in Meper blow molding machines?

The plastic varieties that can be used for blow molding by the hollow blow molding machine include polyethylene, polyvinyl chloride, polypropylene, polystyrene, linear polyester, polycarbonate, polyamide, cellulose acetate and polyacetal resin.

1. The consumption of high-density polyethylene occupies the first place, and it is widely used in the packaging of food, chemicals and processing liquids. Molecular polyethylene is suitable for the manufacture of large fuel tanks and barrels.

2. Because of its good transparency and air tightness, polyvinyl chloride is widely used in the packaging of cosmetics and detergents. 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 has begun to be used in the packaging of beer and other beverages containing carbon dioxide gas .

3. Linear polyester material is a new type of material that has entered the field of hollow blow molding in recent years. Because its products have the advantages of glossy appearance, excellent transparency, high mechanical strength and good preservation of items in the container, and no environmental pollution during waste incineration, it has developed rapidly in packaging bottles, especially It is most widely used in pressure-resistant plastic food containers.

4. Due to the improvement of resin modification and processing technology, the use of polypropylene is also increasing year by year.
