：【question】 Visits：
Obtaining GB4806 food contact material testing certification for vacuum packaging bags is crucial for compliant product entry into the domestic market.
I. Core Preparations Before Application
1. Clarify Product Information
Specific materials of the vacuum packaging bags (e.g., PE, PA, PET, aluminum foil composite film, etc.)
Intended use of the product (e.g., packaging meat, cooked food, snacks, etc.)
Usage temperature range (e.g., room temperature, refrigeration, freezing, high-temperature cooking, etc.)
2. Select a Compliant Testing Organization
The organization must possess CMA (China Metrology Accreditation) and CNAS (China National Accreditation Service for Conformity Assessment) qualifications.
Prioritize organizations with specialized experience in food contact material testing, such as Dezewei Testing (CNAS registration number: L8083).
Confirm that the organization can test for core GB4806 items such as total migration, specific migration, and heavy metals.
II. Specific Application Process
1. Application and Quotation
Fill out the application form provided by the testing organization and submit company information and product data.
An engineer will provide a testing plan and quotation based on the material and intended use of the vacuum packaging bags.
After confirming the quotation, sign a service agreement and pay the fee.
2. Sample Submission
Provide sufficient and representative samples (usually 10-20 complete packaging bags, subject to institutional requirements).
Submit technical documents such as product material specifications, manufacturing process, and labels simultaneously.
3. Laboratory Testing
Select the appropriate standard based on the material of the vacuum packaging bag (e.g., GB4806.7-2023 for plastic materials, GB4806.8-2022 for paper materials).
Core testing items include:
General items: Total migration (≤10mg/dm²), sensory requirements (no odor, no color migration)
Specific items for plastic materials: Potassium permanganate consumption, aromatic primary amine migration
Specific items for composite films: Peel strength, oxygen permeability, water vapor permeability
Heavy metal testing: Lead (≤1.0mg/kg), Cadmium (≤0.1mg/kg), etc.
4. Report Issuance and Compliance Processing
The testing cycle is typically 5-7 working days.
If the test results meet the standard requirements, the testing organization will issue a formal test report with the CMA/CNAS mark.
The report must be marked with the "Food Contact Use" symbol on the product label and specify the material information.
5. Subsequent Management
The test report is valid indefinitely, but needs to be re-verified annually as the GB4806 standard is updated.
The report must be retained in the product technical documents for future reference; market supervision departments may conduct random checks at any time.
III. Cost Reference
Single Material Vacuum Packaging Bags: 1000-2000 RMB/batch
Composite Material Vacuum Packaging Bags: 2000-4000 RMB/batch
The cost difference mainly depends on the number of testing items and the complexity of the sample.
