Abstract

The invention discloses an inflatable bag air retention performance detection device. The invention further discloses a preparation method of the inflatable bag air retention performance detection device and a detection method adopting the inflatable bag air retention performance detection device. The inflatable bag air retention performance detection device comprises an inflatable bag, the inflatable bag comprises an air column, an air inlet channel and an air inlet, the air inlet is formed in one side of the air inlet channel, a first air valve film is arranged between the air inlet channeland the air column, and the air inlet direction of the first air valve film faces the air inlet channel; the detection device also comprises a detection bag which is connected with the air inlet; gasleaked through the first gas valve membrane is discharged into the detection bag through the gas inlet channel, the volume of the gas leaked through the first gas valve membrane of the inflatable bagcan be known by detecting the gas in the detection bag, the structure is simple, preparation is convenient, and the obtained result is accurate.

Description

technical field [0001] The invention relates to the field of air column inflatable bags, in particular to an air bag gas retention performance detection device and a preparation method and a detection method thereof. Background technique [0002] With the wide application of air column cushioning packaging materials, especially the vigorous development of e-commerce, great opportunities have been brought to the rapid development of air column cushioning packaging, and the application field is rapidly extending to manufacturing packaging. At present, the air column manufacturing industry has no way to test the air retention of the air valve. It is impossible to obtain a clear law of air leakage and service life of the air column bag. The gap in gas retention performance in the environment cannot meet the buffering needs of the increasing product types. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in ...
