According to China's national standard GB4806 series "Safety Standard for Food Contact Materials and Products", PET beverage bottles must pass the GB4806 test before they can be put on the market. The following is a guide to the application process, combining the latest standards and industry practices:
I. Applicable Testing Standards and Items
1. Core Standards
- GB 4806.7-2016 "Plastic Materials and Articles for Food Contact"
- QB/T 2357-1998 "Polyester (PET) Still Beverage Bottles" (Additional Industry Requirements)
2. Mandatory Inspection Items
| Inspection Category | Specific Items
| Basic Safety Indicators | Total Migration (4% Acetic Acid/Ethanol Solution)
| PET-Specific Items | Acetaldehyde Content
| Physical Properties | Sealing, Vertical Load, Drop Strength
II. Application Process (5-7 Business Days)
1. Selecting a Testing Agency
- Prefer laboratories with CMA/CNAS accreditation (such as Dezewei Testing)
- Confirm that the agency supports specialized testing for PET beverage bottles (must cover GB 4806.7 + QB/T 2357)
2. Preparing Materials for Inspection
| Document Type | Requirements
| Product Application Form | Indicate specifications, capacity, and operating temperature range
| Material Description | PET resin type and additive list
| Sample Information | Production dates of different batches (at least three batches)
3. Sample Shipping Requirements
- Whole bottle samples: 12 (complete bottles are required for seal/drop testing)
- Preforms/slices: 200g (chemical migration testing)
- Key points to note: areas prone to migration, such as the bottle thread and the injection point on the bottom of the bottle
4. Laboratory Testing
- Chemical Testing: Simulated high-temperature (40°C, 24h) migration test (acetic acid/ethanol solution)
- Physical Testing: -18°C cold resistance + 1.2m vertical drop
- Acetaldehyde Analysis: Headspace gas chromatography (HPLC-GC)
5. Report Review and Issuance
- The qualified report includes: test method, measured data, and comparison with standard limits
- Timeliness: Default validity period: 1 year (re-inspection required if raw materials are changed)
III. Cost and Cycle Reference
| Project Type | Cost Range
| Basic Chemical Migration Testing | 800-1500 RMB
| PET Specialty Testing | +600-1000 RMB
| Expedited Service | Total Cost x 1.5
IV. Key Considerations
1. Typical Failure Causes
- Excessive plasticizer content in the bottle seal (DEHP ≤ 0.1%)
- Excessive heavy metal migration due to recycled PET
2. Compliance Shortcuts
- Prefer food-grade PET resin
- Avoid printing with inks containing phthalates
3. Extended Certification
- Export products must comply with FDA 21 CFR or EU Directive 10/2011
