According to China's National Food Safety Standards and the latest regulatory requirements in 2025, hamburger wrapping paper, as a material that comes into direct contact with oily foods, must pass the GB4806 series of testing and certification. The following are compliance guidelines and operational instructions:
I. Core Testing Standards and Items
1. Mandatory Standards
| Standard Number | Scope of Application | Key Testing Areas
| GB 4806.1-2016 | General Safety Requirements | Sensory Requirements, Total Migration Control
| GB 4806.8-2016 | Food Contact Paper and Paperboard Materials | Fluorescent Whitening Agents (Prohibited), Lead/Arsenic/Formaldehyde Migration (Under Simulated Oil Conditions)
| GB 9685-2016 | Limits on Additive Use | Bleaching Agents (Chlorine Dioxide ≤ 5 mg/dm²), Oil Repellents (Perfluorinated Compounds PFOA ≤ 0.025 μg/dm²)
2. High-Risk Testing Items (Key Monitoring in 2025)
- Total Migration:
- Under Simulated Oil Conditions (40℃, 24h) ≤ 10 mg/dm² (Requires testing with olive oil or 95% ethanol solution)
- Toxic Substance Limits:
- Pentachlorophenol (PCP) ≤ 0.15 mg/kg
- Polychlorinated biphenyls (PCBs) ≤ 2 mg/kg
- Phthalate esters (6 types) Total ≤ 0.1%
II. Key Steps in the Testing Process
A [Sampling] --> B [Material Layer Separation]
B --> C {Substrate and Coating Testing}
C --> |Paper Base| D [GB 4806.8: Heavy Metals/Fluorescent Agents]
C --> |Waterproof and Oil-Resistant Coating| E [GB 9685: PFOA/FOSA Screening]
D & E --> F [Migration Test]
F --> G [Issuance of CMA/CNAS Report]
III. Common Failure Cases and Improvement Solutions
| Reasons for Non-compliance | Improvement Measures
| Excessive Fluorescent Whitening Agent | Replace the base paper supplier and use unbleached bamboo pulp paper (SDS report required)
| Formaldehyde migration > 15mg/kg | Avoid using urea-formaldehyde resin adhesives; switch to water-based acrylic adhesives (compliant with GB 31604.48-2025)
| PFOA coating residue | Replace with fluorine-free oil-resistant agents (such as plant-based nano-coatings)
IV. New Compliance Requirements in 2025
1. Biodegradable Material Certification:
- If using degradable coatings such as PLA/PBAT, additional GB 4806.12-2025 degradation product toxicity testing is required (effective January 2025).
2. Mandatory Uploading by E-commerce Platforms:
- Platforms such as Tmall and JD.com require merchants to display the GB4806 test report number on product pages (effective July 2025).
V. Enterprise Operation Checklist
1. Material Selection Control
- Prioritize the use of pulp raw materials permitted in Appendix A of GB 4806.8 (such as softwood pulp and sugarcane pulp).
- Avoid using recycled paper (unless proof of aseptic treatment is provided).
2. Key Points of the Test Report
- The report must include: migration test temperature/time curve, coating composition analysis, and a comparison table of measured data.
3. Labeling Specifications
- Mandatory Labeling:
- "Food Contact Use" icon
- Applicable temperature range (e.g., "Maximum heat resistance 60℃")
- Material composition (e.g., "Virgin wood pulp + water-based coating")
