The reason for air leakage in aluminum foil bags is summarized by the manufacturer based on years of experience and customer feedback
1、 The bacterial growth inside food aluminum foil packaging often produces gas, which is one of the reasons for the expansion of food aluminum foil bags. Therefore, before leaving the factory, the product must be thoroughly sterilized.
2、 Sealing of food aluminum foil bag packaging. After food is packaged, the final process involves hot pressing and sealing the packaging bag, and the quality of this process directly affects the sealing performance of the packaging bag. If the final edge sealing is not tight, it will lead to air leakage of the Vacuum packing bag, and air will penetrate into the aluminum foil bag from the air leakage part of the aluminum foil bag. This is another reason for food bagging.
If food bags leak due to the sealing performance of aluminum foil bags, timely detection and control of packaging quality can be achieved through testing. A sealing tester can be used for testing. If the Vacuum packing bag is not well sealed, bubbles can be observed leaking from the edge of the aluminum foil bag during the test. This test result can help quality control personnel adjust production parameters in a timely manner, thereby strictly controlling the safety of food produced.
