As food contact materials, paper and paperboard must comply with the requirements of GB4806 when sold in the Chinese market. Here are the detailed steps for GB4806 testing:
1. Understand the GB4806 standard
GB4806 is the Chinese food contact material testing standard, of which GB 4806.8-2022 (or the previous version GB 4806.8-2016) is specifically for paper and paperboard materials and products. These standards specify requirements for contaminant limits, residue dissolution, and other aspects of paper and paperboard materials and products, as well as hygiene standards such as microbial limits and chemical contaminant limits.
2. Prepare test samples
Sample selection: Select representative paper and paperboard samples to ensure that the samples can truly reflect the overall quality of the product.
Sample quantity: Prepare enough samples according to the requirements of the testing agency for multiple tests.
Sample identification: Clearly identify the samples, including production date, batch number, manufacturer and other information, so that they can be tracked and recorded during the testing process.
3. Submit a test application
Submit a test application to a third-party testing agency with GB4806 testing qualifications and provide the following information:
Product information: including detailed information such as product name, specifications, materials, etc.
Test items: According to the requirements of GB4806 standard, clearly define the items that need to be tested, such as sensory requirements, physical and chemical indicators, migration limits, microbial indicators, etc.
Testing standards: Specify GB4806.8-2022 (or GB 4806.8-2016) as the testing standard.
4. Conduct testing
The testing agency will conduct various tests on paper and paperboard samples in accordance with the requirements of GB4806 standard, including but not limited to the following items:
Sensory requirements: Check the appearance, color, odor, etc. of the sample to ensure that there is no abnormality.
Physical and chemical indicators: Determine physical and chemical indicators such as formaldehyde residue and total migration to ensure compliance with standard requirements.
Microbial indicators: Detect microbial indicators such as total bacteria, coliform group, and Salmonella in the sample to ensure hygiene and safety.
Hazardous substance detection: detect harmful substances that may exist in the sample, such as heavy metals such as lead, mercury, cadmium, and specific organic compounds.
V. Receiving the test report
The testing agency will issue a detailed test report based on the test results, including but not limited to:
Test items: list all test items and corresponding test results.
Test standards: clearly indicate the standards based on which the test is based.
Test results: give the specific values of each test item and the judgment of whether it is qualified.
Conclusion and suggestions: give an overall evaluation and suggestions based on the test results.
VI. Review and filing
The company needs to review the test report to ensure that it complies with relevant standards and regulations. If the report meets the requirements, the company can file the report for subsequent use.
In summary, conducting China GB4806 testing is an important link for paper and paperboard materials and products. It helps to ensure the safety and compliance of products, thereby protecting the rights and safety of consumers.
