What Is The General Purpose Of HDPE Plastic Bottles?

High-density polyethylene (HDPE) resin is produced from the chemical compound ethylene. HDPE bottle is blow-molded. Bottles are used for milk and other liquid products, detergents, shampoos, motor oils, medicines, and cosmetics. Most milk and water bottles use natural-colored high-density polyethylene resin. Bottles for other products usually have colorants added to the resin.

Injection-molded HPDE containers are used for products such as margarine and yogurt. More HDPE bottles are produced than containers. HDPE resin can also be used to make bottle caps and container caps, as well as soft packagings such as sacks and garbage bags. HDPE is also used in many non-packaged products.

Bottles and containers account for 53 percent of HDPE packaging products and 38% of all HDPE products. In the 1970s, high-density polyethylene bottles and containers began to replace heavier metal, glass, and paper packaging. Although the amount of HDPE used in bottles and containers has tripled since 1980, its share of the waste market is still less than 1%. The garbage market share of all HDPE products is 2%.

Most plastic bottles use HDPE resins because they are cheap, resistant to impact and chemicals, and provide superior moisture barriers. HDPE is mainly used to make milk and juice bottles, but due to its chemical resistance, it can also be used to hold household chemicals and detergents. Tinted or colored HDPE bottles have enhanced fracture resistance.
