Paper packaging China GB4806 testing process, GB4806 is the abbreviation of China's national standard "Food Contact Materials and Products Safety Standard", which covers a wide range of food contact materials and products. For paper packaging, the GB4806 testing process includes the following steps:
1. Select a testing agency
First, you need to select a professional testing agency with GB4806 testing qualifications and capabilities. Make sure that the selected agency is authoritative and credible and can provide accurate test results.
2. Prepare samples and materials
Before submitting the test application, prepare the paper packaging samples to be tested and the relevant product manuals, technical materials, etc. These materials will help the testing agency understand the specific situation of the product so that accurate testing can be carried out.
3. Submit the test application
Submit the test application to the testing agency and provide the prepared samples and materials. The testing agency will conduct a series of tests on the samples according to the requirements of the GB4806 standard.
4. Conduct testing
The testing agency will test the following items on paper packaging samples:
- Sensory requirements: Test the color and smell of the packaging paper to ensure that there is no abnormal coloring and odor.
- Physical and chemical indicators: Including but not limited to the detection of the residual amount of heavy metals such as lead and arsenic, as well as the test of formaldehyde, fluorescent substances, etc.
- Microbiological testing: Evaluate the microorganisms that may exist in the packaging paper, such as coliform bacteria, salmonella, mold, etc.
- Special migration indicators: Detect the migration amount of harmful substances in the packaging paper to food or food simulants under specific conditions, such as total migration amount, heavy metal migration amount, etc.
- Physical property testing: May include tests such as wet strength, hot weight loss, peel strength, tensile strength, etc.
- 1,3-dichloro-2-propanol and 3-chloro-1,2-propanediol residues: The new standard GB4806.8-2022 adds these two indicators to control the risk of chloropropanols that may exist in paper.
- Total migration: Use food simulant (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.
- Heavy metals (measured in Pb): Detect the content of heavy metal lead in packaging paper to ensure that it is within the safe range.
- Fluorescent substances: Detect whether the packaging paper contains fluorescent substances such as fluorescent brighteners.
5. Comprehensive analysis
After the laboratory test is completed, the test results are comprehensively analyzed to determine whether they meet the GB4806 standard.
6. Prepare test report
Prepare the test report based on the test and analysis results. The test report will record the test results in detail and give a conclusion on whether it meets the GB4806 standard.
7. Check and issue the report
The original copy of the test report will be issued after checking the draft. Enterprises can use the test report for product sales, bidding, e-commerce platform entry, etc.
Conclusion
The GB4806 testing process for paper packaging includes the steps of selecting a testing agency, preparing samples and materials, submitting a testing application, conducting testing, comprehensive analysis, preparing a test report, and checking and issuing a report. Enterprises should conduct testing in strict accordance with the requirements of the GB4806 standard to ensure the safety and compliance of paper packaging.
