Enterprises need to submit samples of food packaging bags to be tested to the testing agency. When submitting samples, companies should ensure the authenticity and representativeness of the samples, and provide relevant product instructions, technical data and other information so that testing agencies can better understand product characteristics and testing needs.
The testing agency will conduct a preliminary inspection of the submitted samples to confirm whether the samples meet the testing requirements. If the sample does not meet the requirements, the testing agency will notify the company to resubmit the sample.
