These testing projects ensure that food ziplock bags will not release harmful substances when in contact with food, ensuring food safety and consumer health. If the food ziplock bag passes all these tests, it will obtain the corresponding DGCCRF certification, which is an important certificate for its legal sale in the French market.

DGCCRF testing process for food ziplock bags:

1. Understand regulations and standards: First of all, you need to have an in-depth understanding of the French DGCCRF regulations and standards on food contact materials, including material composition restrictions, production process supervision, product labeling and instructions for use, etc.

2. Prepare samples: Prepare samples of food ziplock bags that meet the requirements of French DGCCRF to ensure that the samples are free of defects, damage and other problems.

3. Choose a testing agency: Choose a testing agency accredited by the French DGCCRF. These agencies usually have professional testing equipment and personnel to ensure the accuracy and reliability of the test.

4. Submit application: Submit a testing application to the testing agency, and attach detailed information about the product, such as ingredients, manufacturing process, usage, etc. At the same time, samples need to be provided for testing.

5. Conduct testing: The testing agency will conduct various tests on the food ziplock bags in accordance with the requirements of the French DGCCRF. These tests may include material composition analysis, migration testing (evaluating whether substances in the material will migrate into food), toxicity testing, etc. . In addition, it may also be necessary to test the heat resistance, cold resistance and other physical properties of the ziplock bag.

6. Obtain the test report: After the test is completed, the testing agency will issue a test report detailing the test results. These results will be used to evaluate whether food ziplock bags meet the requirements of the French DGCCRF.

7. Audit and certification: If the food ziplock bag passes all tests and meets the requirements of the French DGCCRF, the testing agency will issue the corresponding certification certificate. This certificate is an important proof that the product can be sold legally in the French market.

In addition, DGCCRF's test items may include comprehensive migration testing, sensory testing, heavy metal dissolution testing, etc. to ensure that food contact materials will not cause contamination to food, thereby protecting the health and safety of consumers.
