Scope

This part of GB/T 39690 specifies the naming system and classification basis for recycled mixtures of polypropylene (PP) and polyethylene (PE).
This part applies to recycled mixtures of polypropylene (PP) and polyethylene (PE) from flexible or rigid PP and PE materials used in molded and extruded consumer packaging. It does not apply to recycled materials from packaging materials for transporting, handling, or storing dangerous goods.
This part does not apply to mixtures of recycled resins and new resins.
This part does not apply to mixtures containing special types of PE or PP, such as PE-UHMW and TPO.
The types of PP and PE recycled mixtures are distinguished by a classification system based on the following specified performance levels:
a) Components;
b) Melt mass flow rate;
c) Density;
d) Color.
This does not mean that materials with the same name necessarily have the same performance. This part of GB/T 39690 does not provide engineering data, performance data, or data required to illustrate the specific uses and/or processing methods of the materials. If additional performance data is necessary, it should be measured in accordance with the provisions of ISO 18263-2, if feasible.
