When PEVA (polyethylene-vinyl alcohol copolymer) materials are used in food contact applications, they need to follow a series of testing standards set by the US FDA to ensure their safety and compliance. These standards mainly include:
1. Chemical substance testing: Ensure that PEVA materials do not contain chemicals harmful to the human body, including heavy metal content, organic tin content, polycyclic aromatic hydrocarbon content, etc.
2. Microbial testing: Ensure that the PEVA material has sufficient antibacterial properties to prevent the growth and reproduction of microorganisms. Tests include Escherichia coli, Staphylococcus aureus, Salmonella, etc.
3. Physical performance testing: Evaluate the physical properties of PEVA materials, such as tensile strength, tear strength, abrasion resistance, etc., to ensure that it meets the requirements for food contact products.
4. Food contact safety assessment: Carry out food safety assessment, including carcinogenicity assessment, reproductive toxicity assessment, genetic mutation assessment, etc., to ensure that PEVA materials will not cause harm to human health under normal use conditions.
When conducting FDA food contact material testing, the following steps generally need to be followed:
1. Prepare documentation: Gather all necessary documentation including material specifications, previous test results and safety data sheets.
2. Collect samples: Collect samples that are truly representative of food contact materials and handle them carefully to avoid contamination.
3. Choose a certified laboratory: Send samples to a laboratory with ISO/IEC 17025 certification, such as HQTS certified laboratory, to ensure the accuracy and reliability of test results.
4. Select a test method: The laboratory will select an appropriate test method, such as migration assessment and chemical analysis, based on the material type and intended use.
5. Interpretation of results: After the test is completed, the laboratory will provide a detailed report and any harmful ingredients need to be checked against FDA safety limits.
If the test results do not meet the requirements, corrective measures need to be taken to adjust the material formula or manufacturing process, and then retest to ensure compliance with FDA regulations.
In addition, FDA's regulation of food contact materials includes ensuring that food contact substances (FCS) undergo pre-market review through the Food Contact Notification (FCN) process to ensure their safety. FDA's safety assessment of food contact materials includes analysis of test data to determine the amount of FCS migration, as well as toxicology data to ensure safety for consumer exposure.
For food contact materials such as PEVA bags, it is critical to ensure compliance with FDA regulations to protect consumer health and smooth product entry into the U.S. market.
