[0002] The pharmaceutical composite film is the main form of pharmaceutical packaging and is widely used in the packaging of powders, granules, traditional Chinese medicine decoction pieces, etc. As a packaging material and container in direct contact with drugs, its quality requirements are more stringent. To ensure the safety of pharmaceutical packaging, it is necessary to detect the quality of the pharmaceutical composite film, including detecting the strength, air tightness, water resistance, etc. of the pharmaceutical composite film;

[0003] When some existing detection devices detect the strength of the composite film, they apply pressure to it in the vertical direction, but the pressure application area on the composite film is fixed, and the detection accuracy is not high. At the same time, the existing composite film quality detection devices cannot detect the air tightness and water resistance of the composite film simultaneously, and the detection efficiency is low;

[0004] Therefore, a quality detection device for a pharmaceutical composite film is proposed. Content of the Utility Model
