Embodiment Construction
[0010] A method for quickly detecting the sealing performance of a closed flexible packaging bag according to the present invention. First, put a sample of the closed flexible packaging bag and the closed flexible packaging bag to be tested into a container, and seal the container lid; then inflate the container to the rated value of the packaging bag. Pressure and constant pressure for a period of time; finally quickly open the container sealing lid, observe the difference in volume change between the tested flexible packaging bag and the well-closed flexible packaging bag, and obtain the sealing performance of the tested flexible packaging bag. The difference in volume change between the tested flexible packaging bag and the closed flexible packaging bag sample during this process is compared through the container observation window. The volume change of the packaging bag sample can be 10%, which is the amount of difference that can be judged by normal human eyes. When the gas o...
