The classification of the PE bag you know?

The classification of the PE bag you know? There are many kinds of PE bag of classification, below we explain the classification of the PE bag from a different direction. PE bag as the most widely in the plastic bags, which there are several kinds of classification, can be classified from the design, can also be classified from the material, can also be classified PE bag from the function classification 1 classified according to the style of PE bag of classified according to the design can be divided into: 1. PE bag 2. 3 PE zipper bag. PE pocket 4. PE chain bag 5. PE sticky bag from different design features are not quite same, zipper bag is mainly used to receive items, use more in the garment industry and commodity industries. Bag to use more in store shopping. PE the flat arm in arm bag: 2 shall be carried out in accordance with the material classification according to the material classification can be divided into: HDPE, LDPE, LLDPE, Chinese are high density polyethylene, low density polyethylene, linear low density polyethylene. The several kinds of material texture, performance, usage is different. The strength of HDPE, good tensile strength and stress relaxation in low density polyethylene; Wear resistance, electrical insulation, ductility and cold resistance is good; Organic chemistry, good reliability, under the indoor temperature standard, all insoluble organic solvent, acid, alkali and erosion of various acid salt; Plastic film on water vapour and gas hydrophilic small, low water absorption capacity; Anti-aging performance is poor, the natural environmental stress crack resistance than low density polyethylene (LDPE has excellent flexibility, ductility, electrical insulation, compatibility, easy to process performance and certain ventilation rate. The organic chemistry stable performance is good, good alkali resistance, general organic solvents. Superior natural environmental stress crack resistance of the LLDPE, shock compressive strength and resistance to tear properties such as compressive strength, and acid, alkali, organic solvents, such as the widely used to industrial production, agriculture, pharmaceutical, environmental industries such as health and life commodity PE bag: ENDPE/PO/PP/PVC/CPE/PPE/OPP/EVA
