High Density Poly Ethylene (HDPE) is a thermoplastic polymer made from petroleum. As one of the most versatile plastic materials around, HDPE plastic is used in a wide variety of applications, including plastic bottles, milk jugs, shampoo bottles, bleach bottles, cutting boards, and piping. Known for its outstanding tensile strength and large strength-to-density ratio, HDPE plastic has a high-impact resistance and melting point. Besides its use for food applications, it can be found in unusual places, including: Wood plastic composites Plastic surgery, specifically skeletal and facial reconstruction Snowboards Shoe Lasts 3-D printing filament Food and beverage containers
