China GB4806 testing process for food packaging materials. The testing process for food packaging materials in China is mainly based on the GB 4806 series of standards. The following are the detailed steps of the China GB4806 testing process for food packaging materials:
1. Understand the GB4806 standard
Before starting the testing process, companies need to fully understand the specific content and requirements of the GB4806 series of standards. These standards specify various technical indicators and test methods for food contact materials and products, including requirements for heavy metals, hazardous substances, migration, etc.
2. Choose a suitable testing agency
Companies need to choose testing agencies with corresponding qualifications and capabilities. These agencies usually need to have nationally recognized laboratory qualifications and have professional technicians and equipment to conduct testing.
3. Submit test samples
Companies need to submit samples of food packaging materials to be tested to the testing agency. When submitting samples, companies should ensure the authenticity and representativeness of the samples, and provide relevant product manuals, technical data and other information so that the testing agency can better understand the product characteristics and testing requirements.
4. Testing by the testing agency
After receiving the samples, the testing agency will conduct a series of chemical, physical and biological tests in accordance with the GB4806 standard. Common testing items include:
- Evaporation residue: the amount of evaporation residue of the test material in different food simulants.
- Potassium permanganate consumption: the consumption of potassium permanganate by the test material.
- Heavy metal content: the content of heavy metals such as lead, cadmium, arsenic, antimony, and nickel in the test material.
- Decolorization test: whether the test material will decolorize when in contact with food.
- Microbiological detection: whether the test material contains harmful microorganisms.
5. Issuing a test report
After the laboratory test is completed, the testing agency will conduct a comprehensive analysis of the test results to determine whether they meet the GB4806 standard. Based on the test and analysis results, the testing agency will prepare a test report and issue a formal report after checking the draft.
6. Handling the test report
After receiving the test report, the enterprise should carefully read the content of the report and make corresponding processing according to 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 the sample for testing.
7. Follow-up
After the product passes the test and obtains a qualified report, the company should re-inspect the product regularly to ensure continued compliance with the GB4806 standard. In addition, the company should also pay attention to the updates and changes of relevant standards and adjust the production and testing processes in a timely manner.
By following the above steps, companies can ensure the safety of food packaging materials and provide consumers with safer and healthier food.
