High density polyethylene common uses
WebHigh-density polyethylene (HDPE): HDPE features densely packed molecules delivering rigid, robust, and durable bag structure. For that reason, HDPE is used for storing large volumes of weight. Additionally, HDPE bags are opaque, water-, and heat-resistant, meaning that they’re safe for transporting food and sensitive cleanroom applications. WebThe term HDPE is an acronym for high-density polyethylene. The typical density of this resin is 0.950 g/cc and higher. • LDPE resin. The term LDPE is an acronym for low-density polyethylene. The typical density of this resin ranges from 0.910 to 0.925 g/cc. • LLDPE resin. The term LLDPE is an acronym for linear low-density polyethylene.
