LDPE - low density polyethylene

LDPE is the low density version of PE. This has less hardness, stiffness and strength compared to HDPE, but better ductility. It is opaque and only thin foils can be transparent.

LDPE is used for packaging like foils, trays and plastic bags both for food and non-food purposes. Used as protective coating on paper, textiles and other plastics, for instance in milk cartons.
