plastic bags material is usually divided into PP, PE, PVC. Chinese name are polypropylene, polyethylene, PVC, English full name are: polypropylene, polyethylene, polyvinyl chloride

you will find listed above material in front of the abbreviations have word of a p, p represents the meaning of 'multiple polymerization', that is to say, of the average polymer or polymer is made of common low molecular monomer polymerization.

as PP is the Chinese name of polypropylene, English name is polypropylene, the previous representative poly real a p - The meaning of 'multiple, aggregation', behind a P representative propylene 'acrylic' mean. PE, PVC and so on.

are polymer materials, and are of polyolefins. Popular point said they are all plastic raw material, the three are generally granular.

we common some old-fashioned slippers is made of PVC, they become very soft winter summer of hard PVC as win min has much to do. PVC can decompose toxic gas - at high temperature - Chlorine gas. Of the three maximum density of PVC.

ordinary plastic bags are made of PE, its toughness is better, and HDPE (PE High density polyethylene) And LDPE ( Low density polyethylene) , density is different, lead to some of its performance and there is a big difference.

PP is a relatively safe plastic, the plastic on general food packing bag is to use it to do, of course, PP also have grade, packaging used for food must be food grade. Pp in three medium density minimum, can float on the surface of the water.

as the polymer materials are usually can join some other materials to be modified, in its overall performance or superior performance in one area, used for special purposes, modified the price, of course, sometimes increased significantly.
