The following is a detailed analysis of the DGCCRF test report for the export of insulated lunch boxes to France. Due to the fact that insulated lunch boxes are typically composed of multiple materials such as stainless steel liners, plastic shells/lids, silicone seals, etc., the testing process is more complex than that of single material products.
1、 Test object splitting
Insulated lunch boxes are composite products, and DGCCRF requires separate testing of all components that come into direct contact with food. Usually, it needs to be divided into the following three parts for inspection:
1. Stainless steel liner (usually 304 or 316 stainless steel)
2. Plastic components (lids, shells, usually made of PP, PE, Tritan, etc.)
3. Sealing ring (usually silicone)
2、 Specific testing items and standards
1. Stainless steel inner liner
The requirements of French DGCCRF for metal products are more specific than the EU General Standard (EC 1935/2004), following the official French announcement "Note d'information DM/4/B/0016".
Test project: Heavy metal migration test.
Key indicators: Specific migration amounts of metal elements such as chromium, nickel, manganese, iron, cobalt, etc.
Test conditions: Typically, a 3% acetic acid solution is used, heated to a specific temperature and held for a certain period of time (simulating holding hot soup or acidic food).
Difficulty: Many low-priced stainless steels may not pass nickel and manganese release tests.
2. Plastic components
Follow the French regulations on plastic materials (D é cret n ° 92-631) and the EU regulation 10/2011.
Test project:
Comprehensive migration testing: Simulates include water, 3% acetic acid, 10% ethanol, olive oil (or substitutes). Detect whether plastic components have migrated into food.
Specific migration testing: targeting specific monomers or additives (such as formaldehyde, phenol, heavy metals barium, zinc, etc.).
Sensory testing: Testing whether water or food has an odor or discoloration after contact.
Special reminder: If it is made of PP material, pay attention to color transfer; If it is made of PC material (now prohibited for baby bottles and less commonly used for insulated lunch boxes), bisphenol A (BPA) needs to be tested.
3. Silicone sealing ring
Silicone is crucial in DGCCRF testing and is prone to producing non compliant items.
Test project:
Comprehensive migration testing: using water and ethanol simulants.
Volatile organic compounds: This is the focus of silicone testing, detecting whether harmful gases are released at high temperatures.
Peroxide residue: detect sulfurizing agent residue.
3、 Handling process
1. Fill out the application form: Confirm product information and material declaration (detailed BOM table is required).
2. Sample preparation:
Usually 3-5 finished products are required (depending on the specific requirements of the laboratory, if the components are detachable, only the components can be sent).
The sample needs to be kept clean and free of production oil stains.
3. Laboratory quotation and contract signing: Quotation based on material type and color quantity (plastics of different colors usually need to be tested separately).
4. Testing phase: Laboratory simulation migration experiments and chemical analysis. The cycle is usually 5-7 working days.
5. Issue report: After passing the test, the laboratory will issue a French or English version of the DGCCRF compliance test report.
4、 Common nonconformities and pit avoidance guidelines
Based on past experience, insulated lunch boxes are prone to the following issues during DGCCRF testing:
1. Excessive manganese precipitation in stainless steel: Non food grade or inferior 201 stainless steel was used instead of 304 stainless steel.
Suggestion: * It is necessary to use 304 or 316 steel from legitimate channels and request material certification.
2. Excessive VOM of silicone ring: Improper silicone vulcanization process or use of inferior vulcanizing agent.
Suggestion: * Purchase food grade silicone raw materials and require silicone suppliers to provide FDA or LFGB reports as proof of raw material compliance.
3. Plastic lid odor: sensory test failed.
Suggestion: Ventilate the finished product before shipment to reduce residual odors from injection molding.
Summary:
The core of French DGCCRF certification for insulated lunch boxes lies in "material testing". It is recommended to send samples for pre testing before mass production, especially for silicone rings and stainless steel inner liners, to avoid the risk of returns due to non-compliance after mass production.
