Dec 20, 2016

In the United States sales HDPE1/3 for blowing purposes. These range from bleach, oil, detergent, milk and bottles of distilled water to a large refrigerator, car fuel tanks and cylindrical tanks. Blow molding grade properties, melt strength, ES-CR and toughness, and used in sheet and thermoforming applications level similar to similar grades can be used.

Injection-blow molding is often used in the manufacture of smaller vessels (less than 16oz), used for packaging medicine, shampoo and cosmetics. An advantage of this process is the production of bottle automatically to the corner, without later finishing steps like the blow molding process. Despite some narrow MWD grades used to improve surface finish, use width to wide MWD grades.
