What are the differences between PE stretch film and PVC stretch film

To distinguish the difference between PE stretch film and PVC stretch film, we must first understand the difference between PE and PVC?

The scientific name of PVC is polyvinyl chloride. PVC for short is a polymer of vinyl chloride. It has good chemical stability and is resistant to acid, alkali and chemical compounds. It is resistant to moisture, corrosion and flame retardant. The temperature should not exceed 60 ℃ when used, and it will become hard at low temperature.

The scientific name of PE is polyethylene, which is a polymer of ethylene. Non-toxic, easy to color, good chemical stability, cold resistance, that radiation, good electrical insulation.




 
The difference between the use of PVC wrapping film and PE wrapping film in the industry
PVC stretch film polyvinyl chloride is divided into soft plastics and hard plastics. The soft ones are mainly made into films, which are used as packaging materials, rainproof products, agricultural raising films, and can also be used as insulation layers for wires and cables. The hard ones are mainly made of PVC sheets and pipes, the pipes are used for circulating water, and corrosive fluid pipes. Sheets can be used for floors and protective sheets.

PE wrapping film It is suitable for packaging materials of food and medicine, only for food utensils, medical equipment, and also as insulation materials for the electronic industry.
 
PE hand wrapping film is mostly used for winding ordinary wires, but PE is electrostatic adsorption, the adsorption force is not as tight as PVC, it is easy to open at the joint, and it has to be bonded with tape for the second time, causing trouble in use. However, the proportion of PE is lighter than that of PVC, so the cost is still reduced. Moreover, PE is basically not affected by temperature, and has strong stability. Long-term storage is not afraid of scattered wires, so it is still better than PVC. PE is easy to use.
