Talking about the difference between PVC film and PE film

(1), Polyvinyl chloride (PVC) Film: It is a film formed by adding plasticizer, stabilizer, lubricant, functional auxiliary and processing auxiliary into polyvinyl chloride resin through calendering. It is characterized by good light transmission, blocking far infrared rays, strong thermal insulation, soft and easy to shape, good adhesion and good weather resistance. Japan covers about 80% of PVC greenhouse film in facility cultivation. The disadvantage is that the density is high (1. 3g/cm3) , A certain weight of greenhouse film coverage area than polyethylene film (PE) Reduce 1/3, high cost, hardening and embrittlement at low temperature, easy softening and relaxation at high temperature, easy adhesion of dust and soil on the film surface after precipitation of additives, affecting light transmission, and residual film cannot be burned.

(2)Polyethylene (PE) Film: polyethylene greenhouse film is formed by extrusion blow molding of polyethylene resin. Light texture, soft, easy to shape, good light transmission, non-toxic, suitable for all kinds of greenhouse film, plastic film, is the main agricultural film variety in China. Its disadvantages are: Poor weather resistance, poor heat preservation and difficult bonding. If the production of greenhouse film must be modified with additives such as age-resistant agent, drop-free agent and thermal insulation agent, it can be suitable for the production requirements. At present, the main raw materials of PE are high pressure, polyethylene (LDPE)And linear low density polyethylene (L-LDPE)Wait.

(3) Pvc film has the characteristics of high transparency, good gloss and high shrinkage (4) PE Heat Shrinkable film is widely used in the whole package of alcohol, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact resistance and tear resistance, not easy to break, not afraid of moisture, large shrinkage.
