GB/T 46018.1-2025 Plastics—Technical specification for evaluation of recycled plastic products—Part 1:Poly(ethylene terephthalate)(PET) materials
Basic Information
Scope
This document establishes the evaluation principles, content, and methods for recycled polyethylene terephthalate (PET) plastic materials, specifies the evaluation indicators and their weights, and provides verification methods, total score calculation, and evaluation organization forms. This document applies to the evaluation of flake PET (REC) plastic materials (referred to as "bottle flakes") obtained by mechanical recycling of PET plastic packaging bottles, or granular PET (REC) plastic materials (referred to as "pellets or slices") produced by melt extrusion granulation of PET plastic packaging bottles and/or other PET products through mechanical recycling. This document does not apply to the evaluation of PET (REC) plastic materials derived from hazardous wastes such as medical waste, pesticide packaging, or radioactive waste. This document does not apply to the evaluation of PET (REC) plastic materials prepared by processing PET materials and other plastic materials. This document does not apply to the evaluation of chemically recycled PET (REC) plastic materials.
