[0002] Plastic particles are the common name for plastic particles. They are the raw materials for storage, transportation and processing of plastics in the form of semi-finished products. Plastic particles are a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, etc. can be produced from petroleum.
