Guidelines for Handling GB4806 Testing Reports for Plastic Bags for Food Use
1、 Product standard attribution
Plastic bags for food use correspond to different GB 4806 standards depending on the material:
|Material Type | Applicable Standards | Examples
|Plastic | GB 4806.7 | PE bags, PP bags, cling film
|Composite film bag | GB 4806.7 | Aluminum foil bag, vacuum bag
|Disposable tableware | GB 4806.7 | Packaging box, tray
2、 Handling process
Select testing institution → Submit application → Prepare samples and materials → Laboratory testing → Issue report
1. Choose a third-party testing institution with CMA/CNAS qualifications (Dezewei Testing CNAS registration number: L8083)
2. Submit an application to clarify the product material and implementation standards
3. Send samples (usually 3-5 sets required)
4. Complete the testing (cycle approximately 5-7 working days)
5. Obtain the report and review it with a signature
3、 Required materials
Product name, material, specifications
Material formula description (such as types of additives)
3-5 sets of samples (different specifications need to be tested separately)
Production process description (if necessary)
4、 Main testing items
Total migration amount - testing the total amount of substances transferred to food
Potassium permanganate consumption - reflecting the degree of organic matter dissolution
Heavy metals (calculated as Pb) - content of heavy metals such as lead
Discoloration Test - Investigating whether pigments migrate
Specific migration amount - depending on the special substances that may be involved in the material
5、 Precautions
There are slight differences in the testing items between PE bags and PP bags, and it is necessary to clarify the material type
Composite materials require layer by layer analysis, which incurs relatively high costs
Choose a legitimate institution to ensure that the report has legal validity
The report needs to be retained for at least 5 years for regulatory inspection
