Because of people's awareness of environmental protection, people now basically is to use this kind of non-woven bags, but many people think because the non-woven bag is non weaving plastic manufacture, so it is a natural material, in fact this is a misunderstanding, because the non-woven materials used are polypropylene or polyethylene terephthalate, the plastic raw material is polyethylene, although the names are similar, but the chemical structure is far from the same. The chemical structure of polyethylene has very strong stability, it is difficult to degrade, so the plastic bags will need three hundred years to decompose completely, and the chemical structure of polypropylene is not very strong, it is prone to fracture phenomenon of molecular chain to effectively degrade, and can enter into the next cycle in the form of non-toxic environment. In addition to cutting machine equipment manufacturers in this also and you said is, in essence, as a typical polypropylene plastics, waste for environmental pollution is only just ten percent of plastic bags.
