Our common woven bag lining is generally known as PE inner lining bag, waterproof lining bag, common use, can also be used together with the outside, also can be used separately. Plastic bags also have several categories, mainly from the production process and use to distinguish:

From the production process on the difference between hypertension: in polymerization grade ethylene as raw material, oxygen (or air) or organic peroxides as catalyst, in the pipe reactor cargo tank reactor, using 130-280Mpa EHV and 300 Celsius degrees high temperature process polymerization and. Low: in high purity ethylene as raw material, propylene and butene etc. for copolymerization monomer, to alkane as solvent, in the presence of catalyst with high activity, by solution polymerization using a certain temperature (65-85) and pressure 0.1-0.7Mpa, again after separation, drying, mixing, granulation and into.
