Introduction
Analysis of the core content of the standard
GB/T38925-2020 systematically standardizes the sorting quality system of waste composite packaging for the first time, defines three main types of packaging materials: paper-based (≤5% moisture), plastic-based (≤3% moisture), and metal-based (≤3% moisture), and establishes a three-level quality grading system.
Comparison of key technical indicators
| Category | Primary standard | Secondary standard | Test method |
|---|---|---|---|
| Paper-based packaging | Moisture <5%, inclusions <3% | Moisture 5-20%, inclusions 3-10% | Drying weighing method (GB/T13393) |
| Plastic-based packaging | Moisture <3%, inclusions <1% | Moisture 3-10%, inclusions 1-10% | |
| Metal-based packaging | Moisture <3%, inclusions <3% | Moisture 3-10%, inclusions 3-10% |
Sorting process specifications
The standard requires the use of automated equipment such as magnetic sorting and photoelectric sorting. A typical case shows that Hangzhou Fulun Ecological Technology has increased the separation purity of aluminum-plastic composite packaging to 98.7% through a gravity sorting system.
Safety protection: Sorting personnel must be equipped with dust masks and labor protection gloves, and wastewater treatment must comply with GB8978 emission standards.
Recommendations for the implementation of the standard
- Establish a raw material traceability system to distinguish between production waste and post-consumer waste
- Preferentially use X-ray fluorescence spectrometer to detect heavy metal residues
- Grade 3 products should be pre-processed by crushing and cleaning
Technology evolution analysis
Compared with the EU EN643 standard, this standard adds a new metal-based packaging classification, and puts forward clear sorting requirements for composite metals such as tin/steel, reflecting the targeted design of my country's packaging waste characteristics.
