Blow molding is a molding process used in the manufacturing industry to create hollow objects made of plastic. Like other molding processes, it involves the use of heated, liquid material that's forced into a mold cavity under pressure.

(HD / LDPE & PET) chemically inert nature makes it a popular food-grade plastic for blow molding applications like containers carrying solid foods, milk, and fruit juices. HDPE is great for making food-safe containers since it resists corrosion, doesn't absorb much moisture, and doesn't leach chemicals.
