Blister packaging is widely used in the packaging of solid drugs due to its advantages of good protection, transparent and intuitive, easy to use and light weight. In order to prevent the influence of light, heat and oxygen on the drug and ensure that the drug is not affected by moisture and deterioration within the validity period, the blister packaging should have good sealing performance. Relevant national standards have made clear provisions on this, which is also the focus of the production enterprises. Next, Chenchi instrument combined with mfy-01 negative pressure sealing tester to test the sealing performance of blister packaging.
Blister packaging is a kind of packaging method to seal the product between the blister formed by transparent plastic sheet and the bottom plate (made of cardboard, plastic film or sheet, aluminum foil or their composite materials). Sealing performance refers to the reliability of the blister packaging seal, and the integrity of the whole product packaging seal can be ensured through this test Mfy-01 negative pressure sealing tester According to the principle of vacuum, the internal and external pressure difference of the sample immersed in water is produced by vacuumizing the vacuum chamber, and the gas escaping from the sample is observed to determine the sealing performance of the sample; Or by vacuumizing the vacuum chamber, the internal and external pressure difference of the sample is produced. The sample expansion and the recovery of sample shape after releasing the vacuum are observed to determine the sealing performance of the sample. In the process of experiment, the instrument can realize automatic test only by inputting corresponding pressure value and time. The above method is based on the principle of visual inspection, which is a qualitative test method. If you want to quantitatively test the sealing and leakage performance of packaging, you can use the sealing performance test equipment based on the principle of positive pressure method, such as mfy-02 positive pressure sealing tester of Chenchi instrument.
