The Hdpe Bottle is one of the most common plastics used in manufacturing, due to the materials durability and strength. High Density Poly Ethylene (HDPE) is a thermoplastic polymer made from petroleum. While not as clear as Polyethylene Terephthalate (PET) plastic, HDPE bottles and containers can be translucent so that you are still able to see the product inside it. HDPE is great for blow molding applications, particularly food and beverage containers. Hdpe Bottle is very useful and safe.
