PVC sheet (polyvinyl chloride) is a flame retardant with good chemical stability and only produces low tensile cracking internal forces. The properties of the material also include high strength, high stiffness and high hardness, with an operating temperature range of -15 degrees to 60 degrees, and can be welded.

PVC sheets are widely used in food, gifts, clothing, electrical hardware, crafts, toys, daily necessities, educational experimental supplies, medical and health supplies, travel products, electrical appliances, electronic original gas parts, agricultural products, auto parts, anti-theft locks and other plastic, pressure plastic, folding box packaging, stationery production, printing and so on.

PVC sheet has good chemical stability, acid and alkali resistance. In addition, the other advantages of PVC sheet are mainly reflected in the following aspects:

① Good light transmittance, the new film total light transmittance is greater than 85%; The light transmittance of crop light is small, 0.3m wavelength passes only 20%, so it often becomes the material of choice for PVC plastic bags, and polyethylene (PE) shed film passes 60%; After the buckle shed film condenses light, the impact on the light transmittance is smaller than that of the PE shed film, but after a period of use, the light transmittance is reduced due to the precipitation of the plasticizer and the adhesion of dust.

(2) Good moisture, small thermal conductivity, especially at night 6 to 15 meters long surface wave radiation transmission is very small,PVC plastic bags are only 20%(polyethylene film more than 70%), the average temperature of the flow, the ground temperature is 1.23℃ and 1.05℃ respectively higher than polyethylene film.
