There are many related terms for plastic woven bags , and a better understanding of these professional knowledge will be very important for our communication with customers and for our future production. Our editors summarized the terms of some woven bags through a period of summary, and we hope to bring convenience to our friends and users.
1. Permeability: Liquid molecules or gas molecules can diffuse from one side of the polymer film to the other. This phenomenon is called infiltration or dialysis, and it is a common teaching in the related materials used in woven bags.
2. Density: The density of woven bags is a rule we commonly use in daily production. The molecules form dense molecular chains. The denser the accumulation of molecular chains, the higher the density. LDPE density is 0.92-0.93CM, PP density is 0.90-0.91CM. Resin density depends on the number of short and branch chains in the resin molecule. This kind of data of woven bags mostly means that the resin has low crystallinity and the value is not strong enough, so the density is low and the crystal density is high.
