LDPE coating grade can be rolled flat with a low permeability to vapor. It is characterized by good thermal sealing property, broad molecular weight distribution, high degree of branching, good adhesive bonding when used as coating, and is suitable for high-speed extrusion coating.
LDPE coating grade is mainly used for coating paper, paperboard, BOPP, BOPET, BOPA, aluminum foil and other base materials
to package food, liquids, powder, medicine, agricultural-use material and chemical products. The resin is currently widely used for package paper, bowls, cups and fabric bags and producing adhesive labels, photographic paper, soft packaging material for packing food and medicine and aseptic packages containing milk, beverage and liquid.

Package, Storage and Transportation
The resin is packaged in polypropylene woven bags. The net weight is 25Kg/bag.
The resin should be stored in a drafty, dry warehouse and away from fire and direct sunlight. It should not be piled up in the open air. During transportation, the material should not be exposed to strong sunlight or rain and should not be transported together with sand, soil, scrap metal, coal or glass.
