After the PVC sheet is mixed with additives and plasticized, a three-roller or four-roller calender is used to form a transparent or colored film with a specified thickness.

PVC 片材有什么用途

What are the uses of PVC sheets?

PVC 片材与添加剂混合、塑化后，利用三辊或四辊压延机制成规定厚度的透明或着色薄膜，用这种方法加

工薄膜，成为压延薄膜。也可以通过剪裁，热合加工包装 袋、雨衣、桌布、窗帘、充气玩具等。宽幅的透

明薄膜可以供温室、塑料大棚及地膜之用。经双向拉伸的薄膜，所受热收缩的特性，可用于收缩包装。

After the PVC sheet is mixed with additives and plasticized, a three-roller or four-roller calender is

used to form a transparent or colored film with a specified thickness. The film is processed in this

way to become a calendered film. It can also be processed by cutting and heat sealing to process

packaging bags, raincoats, tablecloths, curtains, inflatable toys, etc. The wide transparent film can

be used in greenhouses, plastic greenhouses and mulch films. Biaxially stretched films can be

used for shrink packaging due to their thermal shrinkage properties.

软质 PVC 混炼时，加入适量的发泡剂做成片材，经发泡成型为泡沫塑料，可作泡沫拖鞋、凉鞋、鞋垫、及

防震缓冲包装材料。也可用挤出机基础成低发泡硬 PVC 板材和异型材，可替代木材试用，是一种新型的建

筑才材料。

When mixing soft PVC, add an appropriate amount of foaming agent to make a sheet, which is

foamed and molded into foam plastic, which can be used as foam slippers, sandals, insoles, and

shock-proof buffer packaging materials. An extruder can also be used to make low-foaming hard

PVC sheets and special profiles, which can be used as a substitute for wood and are a new type of

building material.
