The plastics industry is an important pillar industry of the national economy. With the rapid development of my country's plastics industry and the large-scale use of plastic products, plastics Recycling and recycling is an important issue facing the industry and one of the ways for the sustainable development of plastics. At the same time, it is also a solution to "white pollution", etc. Environmental issues provide an effective way. At present, there is no product standard in the field of plastic recycling in my country, and there is no standard to follow in the industry. Therefore, GB/T 40006 "Plastic Re Raw Plastics" National Standard. According to the characteristics of plastic products, this standard consists of 12 parts. General requirements for naming, terminology and odor level, restricted substance content, radioactivity, etc., the remaining parts are based on the type of plastic except for the general requirements of the Chinese It specifies the technical requirements for recycled plastics of this kind of material. This standard is composed of the following 12 parts under the general title ``Plastic Recycled Plastics''.

1.General rules;

2.Polyethylene (PE) material;

3.Polypropylene (PP) material;

1 Scope

Part 9 of China's national standard series for recycled plastics, covering PET. It specifies the classification and naming, the requirements, the test methods and the inspection rules. PET is the success story of plastics recycling: bottles are collected in enormous quantity, they are made of one polymer, they are easy to identify and separate by density, and the recycled material has a real market in fibre, sheet and new bottles. China is both the largest producer of PET and the largest processor of recycled PET fibre. The technical constraint is intrinsic viscosity, which is the industry's proxy for molecular weight: every melt cycle and every trace of moisture cuts the chains, and the viscosity determines what the material can be made into - bottle grade needs the highest, sheet less, and fibre least. That is why the recycling chain is a cascade, and why the grading in this part is built around that number.
