Food Contact Materials (FCM) refer to materials that come into contact with food under normal or foreseeable conditions of use but do not themselves constitute part of the food. This comprehensive guide to China's GB4806 Food Contact Materials testing for 4-compartment lunch boxes (four-compartment lunch boxes) integrates core processes and key points:
I. Testing Standards and Scope of Application
1. Core Standards
- GB4806.1-2016 (General Safety Requirements)
- GB4806.7-2016 (Plastic Materials and Products), applicable to lunch boxes made of plastic materials such as PP/PS.
- Special Requirements: If sealing strips are included, additional compliance with GB4806.11-2016 (Rubber Materials) is required.
2. Applicable Products
4-compartment lunch boxes that come into direct contact with food, including the box body, lid, and seal.
II. Mandatory Inspection Items
According to GB4806.7, plastic lunch boxes must be tested for the following:
1. Physical and Chemical Properties
- Evaporation Residue: The amount of extractable matter in 4% acetic acid, 20% ethanol, 95% ethanol, and isooctane simulant (indicating oil and acid resistance).
- Potassium Permanganate Consumption: To detect organic matter migration (≤10 mg/kg).
- Heavy Metal Migration: Lead, cadmium, arsenic, chromium, etc. (≤1 mg/kg for lead).
2. Special Items
- Discoloration Test: If the lunch box contains color printing or coating.
- Sealing Test: To test the sealing performance of the snap-fit structure (not a standard requirement, but often required by e-commerce platforms).
III. Application Process (5-10 business days)
1. Laboratory Selection
- Must hold CMA (China Metrology Certification) and CNAS (National Accreditation Service) certification (Dezewei CPC No.: 1552). Preference is given to institutions that support Amazon audits (for e-commerce sales).
2. Submitted Materials
- Product material list (e.g., PP, silicone seal), design drawings, and operating temperature specifications.
- Copy of business license (stamped).
3. Samples for Inspection
- Submit ≥ 3 lunch boxes from the same batch (including different colors/components). It is recommended to include samples in the closed state.
4. Laboratory Testing
- Routine testing: 5-7 days, microbiological testing: up to 10 days.
5. Report Issuance
- Electronic reports will be sent within 1 day, expedited paper reports will be mailed within 3 days.
IV. Fees and Turnaround
| Project | Fee Range | Turnaround
| Basic Testing | ¥500-1500 | 5-7 business days
> Note: Fees vary depending on the laboratory and the complexity of the lunch box (e.g., multiple layers, coatings).
V. Key Compliance Points
1. Labeling Requirements
- Must include the "Food Contact" label, operating temperature range, and material name.
Example:
> *"This product's food contact PP plastic complies with GB4806.7-2016, and is suitable for temperatures between -20°C and 120°C."
2. Annual Maintenance
- Annual random inspections of 10% of products are required, and re-testing is required if the material is changed.
3. E-commerce Platform Requirements
- Platforms like Amazon require a PDF test report, specifying the laboratory's CMA/CNAS number (Dezewei CNAS registration number: L8083).
