Blister packaging raw material PVC polyvinyl chloride film

The consumption of PVC in the field of PVC film ranks third, accounting for about 10%. After PVC and additives are mixed and plasticized, a three-roll or four-roll calender is used to form a transparent or colored film with a specified thickness, and the film is processed by this method to become a calendered film. It can also be cut and heat-sealed to process packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. The wide transparent film can be used for greenhouses, plastic greenhouses and mulching films. The biaxially stretched film has the characteristics of thermal shrinkage and can be used for shrink packaging.
