Abstract: The application proposes a non-destructive testing method for the sealing degree of the small cigarette box packaging, which includes placing the small cigarette box to be tested in an airtight chamber, using a balance cabin to quickly form a stable negative pressure in the airtight chamber; The pressure change of the sealed chamber is continuously measured until equilibrium, and the data model is analyzed and established by using Darcy's law, Fick's diffusion law and the physical process of molecular kinetic theory. Through the non-destructive testing method for the sealing degree of the small cigarette box packaging of the present invention, the traditional destructive measurement (damaged small box packaging) for measuring the sealing degree of cigarette small box is changed into non-destructive testing; The test results have specific physical meaning; The test time of a single sample is reduced to ? of the time of destructive test.
