Introduction

Analysis of the core content of the standard

Characteristic category	Test items	Method standard	Technical points
Basic characteristics	Melt mass flow rate	GB/T3682.1	Test temperature 190℃, load 2.16kg
	Tensile properties	GB/T1040 series	Injection molding specimens are used in the arbitration method
	Impurity content	Appendix B	Count of particles above 0.1mm
	Harmful elements	GB/T26125	Detection of six restricted substances
	Odor level	Appendix A	6-level evaluation system

Key technical requirements

The standard clearly defines PE recycled materials as polyethylene materials that have been pre-treated and melt-granulated, with an ash content of ≤0.5% and a moisture content of ≤0.2%. In terms of tensile properties, the difference between recycled materials and virgin materials should be controlled within the range of ±15%.

Innovation in testing methods

Appendix B: The first thin film method for testing impurities: the sample is pressed into a 0.1-0.3mm film, and the number of impurities above 0.1mm is counted. This method can trace the raw material filtration process. If >1mm impurities are found, it means that it has not passed the 40-mesh filter.

Quality assurance system

Raw material traceability: it is required to record the source and batch information of raw materials
Process control: set key parameters such as melting temperature (recommended 180-220℃), pressure, etc.
Finished product inspection: each batch needs to test at least 5 basic characteristics

Industry application suggestions

For packaging material manufacturers, it is recommended to focus on melt index and odor indicators; toy manufacturers should strengthen the detection of heavy metal migration (refer to GB6675.4). When the proportion of recycled materials exceeds 30%, all mechanical properties need to be retested.
