Scope: This document specifies the classification and naming, requirements, test methods, inspection rules, signs, packaging, transportation and storage of polyethylene recycled plastics. This document is applicable to recycled polyethylene plastic granules made from waste polyethylene plastics through screening, sorting, cleaning, melt extrusion granulation and other processes (including granulation processes such as stranding, hot cutting and/or water cutting) , the matrix of the polyethylene recycled plastic is all ethylene homopolymers specified in GB/T1845.1 and other ethylene copolymers with a mass fraction of 1-olefin monomers less than 50% and non-olefin monomers with functional groups not greater than 3%. things. This document does not apply to polyethylene recycled plastics from medical waste, hazardous waste such as pesticide packaging, and radioactive waste. This document does not apply to polyethylene and polypropylene mixed recycled plastics.
