[0002] Plastic particles are raw materials for the storage, transportation and processing of plastics in the form of semi-finished products. [1] Plastic is a kind of high polymer material, which can be made of ethylene, propylene, chloroethylene, styrene and other substances by using petroleum as raw material. The molecules of these substances can react with each other under certain conditions to form compounds with very large molecular weight, i.e. high polymers.
