Birch Plastics Low-Density Polyethylene (LDPE)

Birch Plastics Low-density polyethylene (LDPE) has a highly diverse chain structure with a combination of both small and large side chains. The density of LDPE ranges between .910-.940 kg/ m3. LDPE exhibits high flexibility and retention of properties at low temperatures. Low-density polyethylene (LDPE) offers excellent corrosion resistance and low moisture permeability. LDPE can be used in applications in which corrosion resistance is of utmost importance while stiffness, high temperatures and structural strength are not. LDPE is a highly flexible type of polyethylene. It is used for strong, flexible consumer items such as screw caps and lids for bottles. LDPE is also commonly found in consumer packing, bags, bottles and liners.
