Product Description
Low density polyethylene, also known as high pressure polyethylene (LDPE), is the lightest variety of polyethylene resin, is milky, tasteless, odorless, non-toxic, non-glossy surface waxy particles. 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.

Low density polyethylene has the following characteristics:
(1) The film is a micro milky transparent color, soft. The strength is smaller than high density polyethylene, and the impact strength is larger than high density polyethylene.
(2) cold resistance, low temperature resistance and high temperature resistance. Thicker film can withstand 90℃ hot water soaking sterilization process.
(3) Good moisture-proof performance, stable chemical performance, insoluble in general solvents.

(4) It has large air permeability, so when it is used as easy to oxidize food packaging, the storage period of its contents should not be too long.

(5) poor oil resistance, products can be slowly dissolved. When packing food containing fat, it will make the food taste stale after long storage.
(6) long-term ultraviolet and thermal action will be aging, affecting its physical properties and dielectric properties.
(7) The melting point is 110~115℃, the processing temperature is 150~210℃, if in the inert gas, the temperature can reach 300℃ is still stable. But the melt and oxygen contact easily degradation.
