Obtaining a GB4806 test report for takeaway food containers requires a step-by-step approach. From initial preparation to receiving the report, every step must be meticulous to ensure compliance and validity, allowing the product to smoothly enter the market. A complete guide to obtaining a GB4806 test report for takeaway food containers:
Based on the latest regulatory requirements in 2025 and industry experience, the following are the complete operational steps from document preparation to report issuance:
I. Initial Assessment and Document Preparation
1. Clarify Product Information
Core Parameters:
Material Type (Plastic/Paper/Degradable Material, specifying PP/PS/PET/PLA, etc.)
Product Specifications (e.g., size, capacity, whether with a lid/divider)
Intended Use (Whether for microwave heating, containing acidic/oily foods)
Key Documents:
Product Formula (Plastic food containers must specify the name and content of additives, such as plasticizers, masterbatches)
Brief Description of Manufacturing Process (e.g., injection molding/blister forming, whether printed/coated)
Brand Name, Model, and Batch Number
2. Test Item Confirmation
Select the corresponding test items based on the material (refer to the "Test Items" section above), with key points highlighted:
Mandatory Tests: Sensory requirements, total migration, heavy metal migration
Material-Specific Tests: For example, test for fluorescent whitening agents on paper lunch boxes, and for biodegradable lunch boxes, test for biodegradability rate.
Special Scenarios: Microwaveable lunch boxes require additional temperature resistance testing (121℃, 30min).
II. Selection and Commissioning of Testing Institutions
1. Qualification Requirements
The laboratory must be selected and possess both CMA certification (China Metrology Accreditation) and CNAS accreditation. Reports must bear both seals to be legally valid.
▶ Recommended Institution: Dezewei Testing CNAS Registration No.: L8083
2. Commissioning Process
Submit the "Testing Application Form" (including company information, product details, and testing items)
Institutional Quotation (approximately 1000-2500 RMB for basic single material items)
Sign the Commissioning Agreement (clarifying testing standards, cycle, number of reports, and confidentiality clauses)
III. Sample Submission and Testing Implementation
1. Sample Requirements
Quantity: 3-5 complete sets of samples (including lids and packaging; if multiple colors/specifications are available, they must be provided separately)
Status: Unused, brand new products; labeled "Submitted Sample" and submission date
Special Handling: Food boxes with printed patterns must have the material of the printed area clearly marked.
2. Testing Cycle
Regular Items: 5-7 working days (physical properties + chemical migration testing)
Expedited Service: 3-5 working days (fees increase by 30%-50%)
IV. Report Issuance and Result Response
1. Report Content Review
Upon receiving the report, please verify the following information:
Basic Information: Product name, model, testing standard number (e.g., GB 4806.7-2023)
Testing Data: Comparison of measured values for each item with standard limits (all must meet the standards)
Key Markings: CMA/CNAS seal, testing organization's official seal, and seal across the binding.
2. Non-compliant Handling Solutions
Physical Failures (e.g., poor sealing, temperature deformation): Optimize production processes (e.g., adjust injection temperature, replace molds)
Chemical Exceeding Standards (e.g., heavy metal migration, evaporation residue): Trace raw material suppliers, replace with environmentally friendly materials (e.g., switch to food-grade masterbatch)
Retesting Process: Resubmit samples after rectification. The testing agency can provide targeted retesting services (cost is 50%-80% of the original item).
V. Report Application and Subsequent Management
Validity Period: The report is valid indefinitely, but retesting is required after product formula, production process, or standards are updated.
Application Scenarios: E-commerce platform entry (scanned copies required for Taobao/JD.com), supermarket supply, market supervision department spot checks
Document Retention: It is recommended to retain the original report and the testing agency's contact information for future verification.
Latest Application Notes in 2025
New Regulations for Biodegradable Lunch Boxes: A biodegradability rate test report (based on GB/T) is required. (20197-2021), otherwise the "degradable" label cannot be used.
Paper lunch box raw material requirements: Recycled waste paper pulp is prohibited; a food-grade pulp certificate from the raw material supplier is required.
