According to the progress report on the global commitment to the new plastic economy jointly prepared by the Alan MacArthur Foundation and the United Nations Environment Programme, the total PCR content of companies that signed the global commitment increased from 4.8% in 2018 to 10.0% in 2021.
The report states that since 2018, more than half of the contracted companies have reduced their use of native plastics, but in 2021, the total amount of native plastic used by globally committed contracted companies has risen again, returning to 2018 levels. To achieve the overall target of 26% by 2025, brand owners and retailers need to continue to double their efforts to increase the use of recycled plastics. Although some companies have already achieved their established goals ahead of schedule, there are still some companies that need to increase their efforts.

The production of products using PCR materials helps to protect the environment. Raw plastics are usually processed from chemical raw materials, and reprocessing them has significant environmental benefits.
The greater the demand for the application of PCR, the greater its impact on the development of global ecological and environmental protection. This has promoted the recycling of more waste plastic packaging and further promoted the commercial process of waste recycling. This means that less plastic ultimately enters landfills, rivers, and oceans, reducing environmental pollution to the Earth and increasing environmental protection for everyone
Polyethylene terephthalate is the main type of thermoplastic polyester, commonly known as polyester resin. It is synthesized by exchanging dimethyl terephthalate with ethylene glycol ester or esterification with terephthalic acid and ethylene glycol to first synthesize dihydroxyethyl terephthalate, and then undergo condensation reaction to obtain it. Together with PBT, it is collectively referred to as thermoplastic polyester or saturated polyester.
In the early days, almost all PET was used for synthetic fibers (commonly known as polyester or Dacron in China). Since the 1980s, PET has made breakthroughs as an engineering plastic, with the development of nucleating agents and crystallization accelerators. Currently, PET, together with PBT, is used as a thermoplastic polyester and has become one of the five major engineering plastics.
PET is divided into fiber grade polyester chips and non fiber grade polyester chips. ① Fiber grade polyester is used to manufacture polyester short fibers and polyester filament, and is a raw material for polyester fiber enterprises to process fibers and related products. Polyester is the variety with the largest production in chemical fibers Non fiber grade polyester also has applications in bottles, films, and other fields, widely used in packaging, electronics, medical and health, construction, automobiles, and other fields. Among them, packaging is the largest non fiber application market for polyester and also the fastest-growing field for PET. Widely used as fibers, engineering plastic resins can be divided into two categories: non engineering plastic grade and engineering plastic grade. Non engineering plastic grade is mainly used for bottles, films, sheets, and baking resistant food containers.
PET is a milky white or light yellow, highly crystalline polymer with a smooth and glossy surface. It has excellent physical and mechanical properties over a wide temperature range, with a usage temperature of up to 120 ℃. Its electrical insulation is excellent, and even at high temperatures and frequencies, its electrical performance is still good. However, it has poor corona resistance, creep resistance, fatigue resistance, friction resistance, and dimensional stability. PET has ester bonds and can decompose under the action of strong acids, bases, and water vapor. It is resistant to organic solvents and has good weather resistance. The disadvantages are slow crystallization rate, difficult molding processing, high molding temperature, long production cycle, and poor impact performance. Generally, the processing and physical properties of the resin are improved through methods such as reinforcement, filling, and blending, with a significant effect of glass fiber reinforcement, which enhances the rigidity, heat resistance, drug resistance, electrical properties, and weather resistance of the resin. However, the drawback of slow crystallization speed still needs to be improved by adding nucleating agents and crystallization promoters. Adding flame retardants and flame retardants can improve the flame retardancy and self extinguishing properties of PET.
PETG is a transparent plastic, an amorphous copolyester. The commonly used comonomer for PETG is 1,4-cyclohexanedimethanol (CHDM), also known as polyethylene terephthalate-1,4-cyclohexanediol ester. It is a product of condensation polymerization of terephthalic acid (PTA), ethylene glycol (EG), and 1,4-cyclohexanedimethanol (CHDM) monomers. Compared with PET, it has more 1,4-cyclohexanedimethanol copolymer monomers, and more ethylene glycol copolymer monomers than PCT. Therefore, the performance of PETG is significantly different from PET and PCT, and it has its unique characteristics.
So far, only two companies in the world, Eastman in the United States and SK in South Korea, have relatively mature technologies. With the increase of CHDM in the copolymer, the melting point decreases, the glass transition temperature increases, the crystallinity decreases, and finally an amorphous polymer is formed. The content of CHDM in PETG is generally suitable between 30% -40%. Has good viscosity, transparency, color, resistance to chemical agents, and stress whitening ability. It can be quickly hot formed or extruded and blown into shape. The viscosity is better than acrylic acid (acrylic).
PETG products are highly transparent and have good toughness, making them suitable for forming thick walled transparent products. PETG has excellent processing and molding performance, and can be designed in any shape according to the designer’s intention. Traditional molding methods such as extrusion, injection molding, blow molding, and vacuum molding can be used, which can be widely used in markets such as sheet materials, high-performance shrink films, bottles, and profiles. At the same time, its secondary processing performance is excellent, Regular machining modifications can also be carried out.
The full name of PCR is Post Consumer Recycled Material, which refers to recycled materials such as PET, PP, HDPE, etc. According to statistics, the material recycling rate of high-value waste plastics in China has reached about 30%, which is 2.4 times the global average material utilization rate. The total amount of material recycling in China is about 19 million tons per year.
PCR materials are extremely valuable. Usually, waste plastics generated after circulation, consumption, and use can be transformed into valuable industrial production materials through physical or chemical recycling, achieving resource regeneration and recycling. For example, the waste plastics generated from consumer daily necessities such as lunch boxes, milk bottles, lychee frames, shampoo bottles, mineral water bottles, washing machine buckets, etc. are recycled, sorted, crushed, cleaned, and then processed for the production of new plastic raw materials.
So how to choose a PCR material supplier? Firstly, it is necessary to choose a PCR environmentally friendly raw material supplier with authoritative certification. At present, the mainstream international PCR material certification institutions are GRS and other certifications, which help enterprises regulate the PCR market and smoothly enter the international market. As a PCR material, it is important to define the source of recycling, which requires official authoritative certification, and GRS is the authoritative PCR material certification.
This is an international, voluntary, and comprehensive product standard that specifies third-party certification requirements for recycling content, production and sales regulatory chains, social and environmental practices, and chemical restrictions. GRS is applicable to any product that contains at least 20% recycled materials. Starting from the recycling stage, each production stage must pass certification and ultimately end with the last seller in a business to business transaction.
At present, GRS certification may become a favorable passport for product export trade on a global scale. The company’s obtaining GRS certification will, in the short term, enhance its competitiveness in breaking international trade carbon barriers and provide more possibilities for product export trade; In the long run, it has contributed to deepening consumers’ low-carbon lifestyle concept, promoting daily low-carbon behavior, and further enhancing the probability of the company achieving overtaking in the field of energy conservation and emission reduction, empowering innovative development.
PET is a milky white or light yellow highly crystalline polymer with a smooth and glossy surface. Good creep resistance, fatigue resistance, abrasion resistance, and dimensional stability, with low wear and high hardness, possessing the greatest toughness among thermoplastic materials: good electrical insulation performance, less affected by temperature, but poor corona resistance. It is non-toxic, weather resistant, and chemically stable, with low water absorption and resistance to weak acids and organic solvents. However, it is not resistant to hot water immersion or alkali.
The glass transition temperature of PET resin is high, the crystallization rate is slow, the molding cycle is long, the molding cycle is long, the molding shrinkage rate is large, the dimensional stability is poor, the crystallization molding is brittle, and the heat resistance is low. Through the improvement of nucleating agents, crystallization agents, and glass fiber reinforcement, PET not only possesses the properties of PBT, but also has the following characteristics.
1. The hot deformation temperature and long-term use temperature are the highest among thermoplastic general engineering plastics.
2. Due to its high heat resistance, reinforced PET is immersed in a soldering bath at 250 ℃ for 10 seconds without deformation or discoloration, making it particularly suitable for preparing electronic and electrical parts for soldering.
3. The bending strength is 200MPa, the elastic modulus reaches 4000MPa, and the creep and fatigue resistance are also good. The surface hardness is high, and the mechanical properties are similar to those of thermosetting plastics.
4. Due to the fact that ethylene glycol used in the production of PET is almost half as cheap as butanediol used in the production of PBT, PET resin and reinforced PET are the lowest priced engineering plastics with high cost-effectiveness.
In plastic classification, the code name for PET is number 1, which has a wide range of functions:
The main applications in the field of electronic appliances include: electrical sockets, electronic connectors, rice cooker handles, TV yokes, terminal blocks, circuit breaker casings, switches, motor fan casings, instrument mechanical parts, cash counting machine parts, electric irons, and accessories for electromagnetic stoves and ovens; Flow control valves, carburetor covers, window controllers, foot transmissions, and distribution panel covers in the automotive industry; Machinery industry gears, blades, pulley, pump parts, wheelchair body and wheels, lampshade shell, illuminator shell, drain pipe connector, zipper, clock parts, spray parts.
Additionally:
It can be spun into polyester fiber, also known as polyester.

As plastic, it can be blown into various bottles, such as cola bottles, mineral water bottles, etc.
Can be used as electrical components, bearings, gears, etc.
PETG sheets with outstanding hot forming performance are easy to produce products with complex shapes and high stretching ratios. Moreover, unlike PC boards and impact modified acrylic, this type of board does not require pre drying treatment before hot forming processing. Compared with PC boards or acrylic, it has a shorter molding cycle, lower temperature, and higher yield.
The extruded PETG board with toughness is usually 15 to 20 times tougher than general acrylic and 5 to 10 times tougher than impact modified acrylic. PETG sheets have sufficient load-bearing capacity during processing, transportation, and use, which helps prevent cracking.
The weather resistant PETG board provides excellent weather resistance. It can maintain the toughness of the product and prevent yellowing. It contains UV absorbers that can be co extruded into a protective layer, protecting the board from the harmful effects of UV rays. Easy to process PETG sheets, they can be sawn, die-cut, drilled, punched, sheared, riveted, milled, and cold bent without breaking. Minor scratches on the surface can be eliminated with a hot air gun. Solvent bonding is also a routine operation. It is easier to process than general acrylic, impact resistant modified acrylic, or PC board, and can be processed with processes such as flocking, electroplating, and electrostatic discharge.
Excellent chemical resistance PETG board can withstand various chemicals and commonly used cleaning agents. All environmentally friendly PETG board substrates are environmentally friendly materials that comply with food contact management requirements.
Economically, it is cheaper than PC boards and more durable than acrylic.
