Commonly used in packaging applications as it provides an excellent moisture barrier properties and chemical resitance. General uses of HDPE include snack food packages, packaging industrial/household articles, vegitable crates, toys, closures etc
Used in film applications due to its toughness, flexibility and transparancy. LDPE has a low melting point, used to manufacture bags, flexible lids, and is widely used in cable applications for its stable electrical properties.
LLDPE is a tough and flexible plastic and will stretch under stress mainly used in thinner plastic film applications, plastic bags/sheets/pipes and cable insulators for its good electrical properties.
