What are the causes of air leakage in food packaging bags

Reasons for air leakage in food packaging bags 1. Bacteria in food packaging bags multiply and often produce gas, which will cause the packaging bag to swell. Therefore, the product must be thoroughly sterilized before leaving the factory.

The second reason for the air leakage of food packaging bags is that the sealing is not enough. After the food is bagged, the first process to be done is to heat and seal the packaging bag, and the quality of this process will directly affect the sealing function of the food vacuum packaging bag. Assuming that after all, the lax edge sealing will also cause air leakage in the food vacuum packaging bag, and the air will penetrate into the vacuum packaging bag from the leaking part of the food packaging bag.

If the air leakage is caused by this reason, the packaging quality can be found and controlled in time by checking. For example, check whether the seal of the food packaging bag is intact, and whether there are air bubbles leaking from the sealing edge of the food vacuum packaging bag during the inspection process.
