It has good softness, extensibility, electrical insulation, transparency, workability and certain air permeability. Its chemical stability performance is good, alkali resistance, resistance to general organic solvents. Application range of low density polyethylene: suitable for seasoning, pastry, sugar, preserves, biscuits, milk powder, tea, fish floss and other food packaging. Tablets, powders and other medicine packaging, shirts, clothing, knitted cotton products and chemical fiber products packaging. Washing powder,detergent, cosmetics and other daily chemical products packaging. Because of the poor mechanical properties of single-layer PE film, it is usually used as the inner layer of composite packaging bag, that is, multilayer composite film heat-sealing substrate.
