ThomasPlastics are recyclable waste. Plastics are high molecular compounds polymerized by addition polymerization or polycondensation reaction with monomers as raw materials. Their deformation resistance is medium, between fiber and rubber. They are composed of synthetic resin, fillers, plasticizers, stabilizers, lubricants, pigments and other additives.
Expansion materials:
Plastic packaging materials have the advantages of light weight, high strength, good impact resistance, transparency, moisture resistance, beauty, stable chemical properties, good toughness and anti-corrosion. They have widely replaced metals, wood, paper, glass and leather in the field of packaging. Therefore, plastic packaging plays an irreplaceable role in reducing the pressure of resources and energy in China.
Plastic is an important organic synthetic polymer material, which is widely used. However, plastic packaging materials have a fatal weakness, that is, their natural degradation time is long, some for more than 100 years, which has become an increasingly prominent environmental problem and put great pressure on human living environment. Therefore, the recycling of plastic packaging waste is urgent.
