T/CPPIA 1-2018 General Guidelines for Recycled Plastic Particles

Scope

Main technical content: 4.1 The color of recycled plastic pellets should be within the same color range and cannot contain resins of other color systems. 4.2 The size of recycled plastic pellets can be cylindrical, flat, oval, or spherical in regular shapes. Their size should be between 200 and 1000 pellets, and the total amount of large and small pellets should not exceed 5.0% of the total mass. 4.3 Impurities should be calculated based on the entire batch. The mass content of impurities in recycled plastic pellets should be less than 0.5%. 4.4 Surface cleanliness: The surface of recycled plastic pellets should be free from obvious moisture, oil stains, and inorganic powders. 4.5 Composition: Recycled plastic pellets should be made from a single resin or a blend of resins. All pellets should have consistent main resin components, and no pellets containing different resin components should be mixed in. 4.6 Environmental requirements: 4.6.1 Hazardous waste requirements should comply with the provisions of the *National Hazardous Waste List*. 4.6.2 Requirements for toxic and harmful substances should comply with the provisions of GB 5085. 4.6.3 The entire production process of recycled plastic pellets should comply with the provisions of HJ/T 364-2007. 4.6.4 Suppliers have the obligation and responsibility to declare the production process to purchasers, and purchasers should supervise the production process of suppliers. 4.6.5 Recycled plastic pellets should not have obvious irritating odors. The specific odors inherent in the resin should not be treated as odors. 4.6.6 The external radiation penetration dose rate of recycled plastic pellets (including packaging materials) should not exceed the normal natural radiation background value at the import port + 0.25μGy/h.
