introduction

Under the global trend of promoting the use of recycled plastic products, high-quality recycling has become the development direction of the future plastic recycling economy. The requirements should not only focus on whether the quality of recycled plastics meets the application requirements, but also take into account the traceability of the entire recycling system cycle process, Safety, environmental resource impact and other property requirements, in order to meet the increasingly stringent domestic regulations and certification requirements for recycled plastics, recycling is the existing The best choice for disposing of waste plastics. Establish product evaluation requirements covering the entire process of plastic recycling and regeneration, and provide a basis for my country to build an independent recycled plastic certification system. It provides a basis for high-quality recycling, and provides a more applicable and guiding evaluation for the application of recycled plastic products. GB/T 46018 "Technical Specifications for Evaluation of Recycled Plastic Products" is intended to consist of four parts. --- Part 1.Polyethylene terephthalate (PET) materials. The purpose is to establish the Product evaluation requirements for polyethylene terephthalate (PET) materials. --- Part 2.Polystyrene (PS) materials. The purpose is to establish product evaluation criteria applicable to recycled polystyrene (PS) materials. Require. --- Part 3.Polyethylene (PE) and polypropylene (PP) materials. The purpose is to establish the application of recycled polyethylene (PE) and polypropylene Product evaluation requirements for (PP) materials. --- Part 4.Polycarbonate (PC) materials. The purpose is to establish product evaluation criteria applicable to recycled polycarbonate (PC) materials. Require. Technical Specifications for Evaluation of Recycled Plastic Products Part 1.Polyethylene terephthalate (PET) material
