Food packaging containers in China need to undergo GB4806 food contact material testing to ensure their safety. GB4806 is China's national food safety standard that specifies safety requirements for food contact materials and products. The following is relevant information about GB4806 testing of food packaging containers:
1. Standard Overview:
- The GB4806 standard specifies various technical indicators and test methods for food contact materials and products, including requirements for heavy metals, hazardous substances, migration, etc.
- This standard applies to various food contact materials, such as plastics, metals, ceramics, glass, paper and paperboard, coatings, rubber, etc.
2. Test Content:
- Total Migration: Test the amount of dissolved residues of the test material in simulated food to ensure that it will not contaminate the food during use.
- Heavy Metal Migration: Test the migration of heavy metals such as lead, cadmium, chromium, and nickel to ensure that it is within the safety limit.
- Potassium Permanganate Consumption: Test the redox reaction of the test material in the food simulation liquid to evaluate its chemical stability.
- Total amount of aromatic primary amines: The test results should meet the limit requirement of ≤0.01mg/kg.
- Specific migration amount: Migration test for specific harmful substances (such as phthalates, bisphenol A, etc.) to ensure that they do not exceed the regulatory limit.
- Microbiological testing: The total number of microorganisms on the surface or inside the test material to ensure that it meets the hygiene standards.
3. Testing process:
- Understand the standard: Enterprises should fully understand the specific content and requirements of the GB4806 standard to ensure that the product meets the relevant standards.
- Select a testing agency: Select a testing agency with relevant qualifications and capabilities, such as Dezewei Testing.
- Submit test samples: Enterprises need to submit samples of food packaging materials to be tested to the testing agency and provide relevant product manuals, technical data and other information.
- Waiting for the test report: The testing agency will test in accordance with the GB4806 standard and issue the corresponding test report.
- Handle the test report: Enterprises should carefully read the report content and take corresponding measures based on the conclusions and suggestions in the report. If the product meets the GB4806 standard, the company can use the report as the basis for product qualification certification; if the product does not meet the standard, the company needs to make improvements based on the suggestions in the report and resubmit samples for testing.
4. Testing agency:
- Choose a testing agency with relevant qualifications and capabilities, such as Dezewei Testing. These agencies usually have advanced testing equipment and professional technical teams, and can provide accurate and reliable testing services.
5. Importance:
- The safety of food contact materials is directly related to the health of consumers. Through GB4806 testing, the migration of harmful substances can be effectively discovered and controlled to ensure the safety of food.
- There are strict food contact material safety regulations in China and internationally, such as the GB4806 series of standards, US FDA regulations, and EU REACH regulations. Food manufacturers must comply with these regulatory requirements and ensure the compliance of their products through testing to avoid legal risks and economic losses.
In short, GB4806 food contact material testing for food packaging containers is an important part of ensuring food safety. Companies should attach great importance to the safety of food contact materials and ensure that their products meet national and international safety standards through strict testing and quality control.
