Silicone fresh-keeping covers, as daily necessities that come into direct contact with food, can not only ensure product safety through LFGB certification, but also gain consumer trust in the German market and enhance product competitiveness.
Full process guide for LFGB certification of silicone fresh-keeping cover
1、 Core testing items (based on LFGB 1935/2004/EC and BfR standards)
|Test Category | Specific Project
|Basic security testing | Comprehensive migration testing (4% acetic acid, 20 ℃/24h)
|Sensory Testing | Odor and Taste Transfer Assessment (Simulating Food Contact Scenarios)
|Heavy metal detection | Lead (Pb) and cadmium (Cd) leaching amount
|Special Chemical Testing | Total Organic Volatile Matter (VOM)
|Peroxide value (measuring the degree of oxidation of silicone gel)
|Organic tin compounds (such as tributyltin)
|Polycyclic aromatic hydrocarbons (PAHs)
2、 The 6-step authentication process (cycle 5-7 working days)
1. Data and sample preparation
Essential Information:
✅ Ingredients list of silicone fresh-keeping cover (including silicone grade and CAS number of additives, such as "methyl vinyl silicone rubber, CAS 63148-62-9")
✅ Product structure diagram (indicating the materials of sealing rings, pull rings, and other components)
✅ Production process description (such as whether platinum vulcanizing agent is used)
Sample requirements:
⚠️ Provide 3-5 complete finished products (if there are multiple colors/sizes, separate samples need to be sent for each)
⚠️ The sample must be consistent with the mass-produced version (including printing ink and coating)
2. Choose a certification body
Recommended Institution:
▶ Dezewei Testing CNAS Registration Number: L8083
Qualification verification: Confirm that the institution has CNAS/CMA qualifications and the test report can support German customs inspection
3. Quotation and Contract Signing
Cost range: Basic testing (comprehensive migration+sensory+heavy metal) approximately ¥ 1000-2500
Key points of the contract: Clearly define the testing standards (including "compliance with German BfR XV silicone rubber regulations"), report language (bilingual in English/German)
4. Laboratory testing phase
Key nodes:
▶ Comprehensive migration testing: simulating contact scenarios with acidic foods (4% acetic acid) and alcoholic foods (10% ethanol)
▶ Sensory testing: odor/taste evaluation conducted by professional evaluators in a constant temperature environment of 65 ℃
▶ If the test fails (such as VOM exceeding the standard), the institution will provide rectification suggestions (such as adjusting the vulcanization temperature or time)
5. Report issuance and review
Core content of the report:
✅ 16 standard modules (including testing methods, data, and conclusions)
✅ Silicone Material Safety Declaration (Compliant with LFGB § 30-31 Requirements)
✅ Institutional signature and laboratory number (traceability)
Audit focus: Confirm the authorization for the use of the "knife and fork logo" (logo height ≥ 5mm, to be printed on the product or packaging)
6. Market Access and Maintenance
Certificate validity period: 5 years (if there are no changes to the formula or production process)
Subsequent obligations: Save the report and original data for at least 10 years, in preparation for spot checks by the German Federal Agency for Consumer Protection and Food Safety (BVL)
3、 Frequently Asked Questions for Enterprises
Q: Is it necessary to conduct a color transfer test for silicone freshness caps?
A: If the product contains pigments (such as red silicone caps), an additional color transfer test (boiling in 4% acetic acid for 30 minutes) is required to ensure that the dye does not precipitate.
Q: Can the "LFGB Certification" logo be used directly after passing the test?
A: German regulations do not require certificates, and test reports are compliance certificates that can be affixed with a "knife and fork mark" (indicating the authorization of the mark in the report).
Q: Are there any differences in testing items for silicone with different hardness (such as Shore 30A vs 60A)?
A: Hardness does not affect the testing items, but the actual hardness value should be indicated in the report (recorded during testing).
4、 Efficient handling suggestions
1. Advance communication on materials: Requesting MSDS from silicone raw material suppliers can shorten the component confirmation time for testing institutions
2. Choose expedited service: Paying a 30% expedited fee can compress the cycle to 3 working days (applicable to urgent orders)
3. Batch testing discount: If similar products such as silicone ice grids and silicone placemats are certified at the same time, packaging testing can be applied for (cost reduction of 15% -20%)
