LFGB testing is performed on all materials, including products manufactured using the latest technology. According to German LFGB regulations, vacuum-sealed containers, as food contact materials, must undergo the following testing to ensure their safety:
I. General Mandatory Inspection Items
1. Sensory Testing
- Odor and Taste Migration Assessment: Confirms that the container will not release odors or alter the taste of food when in contact with food.
2. Initial Material Inspection
- Basic Component Screening: This includes material type (e.g., plastic, glass, silicone, etc.) and a review of the production process.
II. Core Test Items by Material Classification
Plastic Parts (Can Body/Lid)
| Test Items | Specific Requirements
| Total Migration Test | Simulate food environments (water, alcohol, olive oil) to test for the total amount of soluble hazardous substances
| Heavy Metal Release Test | Limit testing for lead (Pb), cadmium (Cd), chromium (Cr), etc. (e.g., lead ≤ 0.05 mg/kg)
| Migration of Specific Chemical Substances | Phthalates (plasticizers), bisphenol A, etc. (BPA testing is required for PC materials)
Silicone Seals
- Volatile Organic Compound (VOC) Test: Detects organic compounds released at high temperatures.
- Peroxide Value Test: Assess the chemical stability of silicone during aging.
Metal Parts (Snaps/Springs)
- Heavy Metal Analysis (nickel, manganese, etc.) and Special Migration Tests.
Glass Can Body (if applicable)
- Lead and Cadmium Release Test (particularly for glaze decorations).
III. Supplementary Testing for Special Scenarios
1. High-Temperature Resistance Test
- Simulates high-temperature sterilization (e.g., boiling water) to verify the seal deformation rate and harmful substance release.
2. Long-Term Immersion Test
- Continuously monitors changes in migrating substances in contact with acidic/greasy foods.
IV. Certification Process and Timeframe
1. Process Steps:
- Submit product material list and samples → Laboratory separates and tests by material → Issues LFGB report (with "knife and fork" mark).
2. Turnaround Time: 5-7 business days (can be shortened with expedited processing).
3. Cost Estimation:
- Approximately ¥1,000-1,500 for a single material; ¥1,000-2,000 for composite materials (e.g., plastic + silicone + metal).
