Guidelines for Obtaining GB4806 Food Contact Material Testing Reports for Beverage Flexible Packaging
I. What is Beverage Flexible Packaging?
Beverage flexible packaging refers to flexible containers made of multi-layer composite materials such as plastic film, aluminum foil, and paper. Common types include:
| Types | Typical Products | Main Material Structure
| Stand-up Pouches | Juice, Milk Tea, Sports Drinks | PET/AL/PE, CPP/AL/PE
| Spout Pouches | Children's Drinks, Baby Puree | PET/PA/PE + PP Spout
| Bag-in-Box | Wine, Drinking Water | PE/EVH/PE + Outer Cardboard Box
| Transparent Bags | Tea, Cold Brew Coffee | PET/PE, PA/PE
| Metallized Bags | Milk, Soy Milk | LDPE/Aluminum Layer/PE
| Composite Film Rolls | Whole Bag Supply to Downstream Brands | Multilayer co-extrusion or dry lamination
II. Applicable Standards
Beverage flexible packaging is a multilayer composite food contact material. It must be tested separately according to the corresponding standards for each layer and meet general safety requirements:
GB 4806.1-2016 (or new version GB 4806.15-2024): General Safety Requirements
GB 4806.7-2016: Plastic Materials and Articles for Food Contact
GB 4806.9-2016: Metal Materials and Articles for Food Contact (Aluminum Foil Layer)
GB 4806.8-2016: Paper and Paperboard Materials and Articles for Food Contact
GB 4806.10-2016: Coatings and Coatings for Food Contact
GB 31604.1~49: Standards for Test Methods for Each Item
III. Core Testing Items
Physicochemical Testing
Sensory Requirements: Normal color, no off-odor, no turbidity in the soaking solution
Total Migration: ≤ 10 mg/dm² (three layers and above materials)
Specific migration amounts: Lead (Pb) ≤ 1 mg/kg, Cadmium (Cd) ≤ 0.01 mg/kg, Arsenic (As) ≤ 0.01 mg/kg
Evaporation residue: Four simulated solutions: 4% acetic acid, 10% ethanol, vegetable oil, and distilled water
Formaldehyde (paper layer) ≤ 15 mg/kg
Key Concerns
1. Ink migration: Migration of outer packaging ink to inner layers contaminating food
2. Adhesive safety: PU adhesive and VOC residues used in dry-laminated films
3. Aluminum foil layer: Detection of aluminum migration
4. Additive migration: Antioxidants, light stabilizers, plasticizers (PAEs)
5. Aromatic primary amines (may be present in PA layers)
IV. Application Process
Fill out application → Submit documents → Send samples → Laboratory testing → Report issuance → Archiving →
Prepare material list → PDF specification sheet → 3-5 bags of finished products → Simulated Liquid Immersion → Chinese Test Report
Detailed Steps
1. Select a Testing Institution: Choose a third-party testing institution with CMA and CNAS accreditations.
2. Submit Product Information: Material structure, thickness of each layer, printing process, and sealing information.
3. Send Samples: Provide at least 3-5 complete finished bags (including nozzles, caps, and other accessories).
4. Complete the Application Form: Clearly indicate the type of food to be exposed to, the contact temperature, and the contact time.
5. Laboratory Testing: Typically 15-25 working days.
6. Report Issuance: Chinese version of the CMA test report, including conclusions.
V. Required Documents List
| No. | Document Name
| 1 | Product Structure Diagram (including material and thickness of each layer)
| 2 | List of raw materials and sources for each layer
| 3 | Brand, model, and MSDS of inks and adhesives
| 4 | Material description of sealing components (nozzle, cap)
| 5 | Food Types to be Contacted (Acidic/Alcoholic/Oil/Water-based)
| 6 | Expected Operating Temperature (Room/Low/High)
| 7 | Color Photograph + Sample Submission
VI. Costs and Timeframe
| Testing Scope | Cost Range (RMB)
| GB 4806.1 General + 4806.7 Plastics | 800-1500 |
Routine Testing: 5-7 working days
VII. Precautions
Key Risk Points
1. Bag Type Differences: Stand-up pouches, spout pouches, and octagonal seal bags may require separate testing due to structural differences.
2. Printing Layer Orientation: Ink on the outer layer is generally compliant, but reverse printing processes require additional evaluation.
3. Food Type Matching: Acidic foods (fruit juice) → 4% acetic acid simulation solution; Alcoholic beverages → 10% ethanol simulation solution; Oily beverages (dairy beverages) → Vegetable oil simulation solution
4. Temperature and Time Testing Conditions: Room temperature beverages (below 10℃) 24h) / Hot filling (70℃ 2h) / Pasteurization (100℃)
5. Separate testing of seals: Spouts, caps, zippers, and valves must be tested separately according to their materials.
6. SC certificate requirements: Manufacturers must possess a food-related product production license.
7. New standard: Note that GB 4806.15-2024 is in effect; the transition period for the old standard may have ended.
Application suggestions:
Roll material suppliers should complete whole-bag testing in advance to shorten the cycle for downstream brands.
For export products, it is recommended to simultaneously test EU 1935/2004 and FDA 21 CFR, submitting multiple sets of reports at once.
For high-end infant formula and children's beverages, it is recommended to add total migration + 17 phthalates enhanced testing.
Choose a CNAS or CMA accredited institution to ensure the report is valid nationwide and recognized by market supervision departments.
Summary: The core of obtaining a GB4806 report for beverage flexible packaging is multi-material stratified assessment + simulated liquid migration testing. It is recommended that companies introduce testing during the formula design stage to avoid rework due to substandard finished products.
