As food contact materials, food packaging paper must comply with the GB4806 series of standards when sold in the Chinese market. GB4806 testing covers general safety requirements for food contact materials and products, including physical properties, migration testing, leachable testing, food simulation testing, microbial testing, and heavy metal dissolution testing.
GB4806 testing specifically includes the following items:
1. Sensory requirements: Test the color, smell, etc. of the packaging paper to ensure that there is no abnormal coloring or odor.
2. Physical and chemical indicators: including but not limited to the detection of residual amounts of heavy metals such as lead and arsenic, as well as the testing of formaldehyde, fluorescent substances, etc.
3. Microbial testing: Evaluate the possible presence of microorganisms on the packaging paper, such as coliforms, salmonella, mold, etc.
4. Special migration index: detects the migration amount of harmful substances in packaging paper to food or food simulants under specific conditions, such as total migration amount, heavy metal migration amount, etc.
5. Physical performance testing: may include tests such as wet strength, thermal weight loss, peel strength, tensile strength, etc.
6. Residual amounts of 1,3-dichloro-2-propanol and 3-chloro-1,2-propanediol: The new standard GB 4806.8-2022 adds these two indicators to control the possible risk of chloropropanol in paper .
7. Total migration: Use food simulation liquids (such as water, ethanol, olive oil substitute, etc.) to conduct migration tests to evaluate the total amount of chemical substances in packaging materials that may migrate into food.
8. Heavy metal (calculated as Pb): Test the content of heavy metal lead in the packaging paper to ensure that it is within a safe range.
9. Fluorescent substances: Detect whether the packaging paper contains fluorescent substances such as fluorescent whitening agents.
These testing items are designed to ensure that food packaging paper will not cause contamination to food during normal use and protect the health and safety of consumers.
