Polyester (PET) bags, a new woven packaging bags.

PET is polyethylene terephthalate. It's a plastic resin and the most common type of polyester. Two monomers-modified ethylene glycol and purified terephthalic acid-are combined to form the polymer called polyethylene terephthalate. PET was discovered and patented in England in 1941.Polyester is
obtained by polycondensation of polyhydric alcohols and polybasic acid polymer in general. Mainly refers to polyethylene terephthalate (PET), the habits, including polyethylene terephthalate, polybutylene terephthalate (PBT) and poly aromatic esters and other linear thermoplastic resin. Is a kind of high performance, versatile engineering plastics. Also be made of polyester fibers and films.

A Chinese company used a special plastic timber (PET) as the material of woven bags which stirred the whole plastic woven bags industry. After six years of research, this company invented the special material for the production of raw materials woven ( has obtained national patents,as well as many countries and regions applied through PCT). The company introduced: The traditional woven polypropylene and polyethylene are used as a raw material, and the company developed special material is old as raw material bags. And this is extremely rich in raw materials, low prices, it 's the performance exceeded the performance of the current bags, but also greatly reduces the cost of raw materials.

This performance than woven polypropylene bags of superior performance, can be explained by the following points:

1.The tensile strength is 1.5 times that of polypropylene woven bags. The bulk bags could also be used as the material for high-intensity needs.
2.Transparency, gloss higher than polypropylene bags, feel very wide, flat and smooth surface. For the production of transparent bag.
3.Good temperature resistance, can reach 140 degrees. Duration of 48 hours, does not change its properties.
4.Toughness than polypropylene bags, no crack in the weaving of silk.
5.Anti-aging, 2 times that of polypropylene bags, can be used to produce tarpaulin and lawns.

Some experts predict: World production of woven polyethylene bags industry first, and then the production of PP woven bags(also know as PP bags) enhance product quality and applications, and polyester (PET) production of woven bags will surely elevate again product quality and applications.

The key technology to produce polyester (PET) is the equipment bags, with equipment of any enterprise can produce woven polyester (PET) bags. Recently

learned that domestic production of such equipment manufacturers, many years ago on the production of such equipment and exported to foreign countries.
