Virgin Polyethylene Resin LDPE-Pem1850A Granules High Transparent Blow Molded

Low density polyethylene, also known as high pressure polyethylene (LDPE), is the lightest variety of polyethylene resin, which is milky, tasteless, odorless, non-toxic, waxy particles with a dull surface. It has good softness, extensibility, electrical insulation, transparency, ease of processing and certain permeability. Its chemical stability is good, alkali resistance, resistance to general organic solvents.
Low density polyethylene has the following characteristics:
(1) The film is slightly opal transparent and 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. The thicker film can withstand the sterilization process of 90ºC hot water immersion.
(3) moisture resistance is better, chemical performance is stable, insoluble in general solvents.
(4) It has large breathability, so when it is used as a food packaging that is easily oxidized, the storage period of its contents should not be too long.
(5) The oil resistance is poor, and the product can be slowly dissolved. When packaging food containing fat, it will make the food appear rancid after long storage.
(6) Long-term exposure to ultraviolet light and heat will age, affecting its physical properties and dielectric properties.
(7) The melting point is 110~115 ° C, the processing temperature is 150~210 ° C, if in the inert gas, the temperature can reach 300 ° C is still stable. However, contact between melt and oxygen is easy to degrade.
