Non-destructive detection technology for air-tightness of cigarette packets and the application in the research of moisture migration behavior

Scientific sealed packaging allows the quality of cigarette packets stably by blocking the moisture migration during the process of storage and transportation. The gas diffusion behavior inside the cigarette packets follows the pressure difference method, based on the dynamic pressure drop mathematical model and Bernoulli equation, the self-designed non-destructive detection (NDD) of air-tightness...
