Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] Such as figure 1 As shown, the air permeability testing device for packaging materials of the present invention includes an air permeability tester 5, a heating coil 6 and a U-shaped glass tube 7, the air permeability tester 5 is arranged in a constant temperature pool 9, and the air permeability tester 5 It includes a high-pressure air chamber and a low-pressure air chamber. The packaging material to be tested is arranged between the high-pressure air chamber and the low-pressure air chamber. The high-pressure air chamber is located at the lower part of the low-pressure air chamber. A gas output end is connected, the second end of the heating coil 6 is connected with the air inlet pipe 1, the low pressure chamber is connected with the U-shaped glass tube 7 and the second gas output end respectively, and the U-shaped glass tube 7 is provided with colored alcohol.
