It is suitable for sealing test of packaging bags, bottles, tubes, cans, boxes, etc. in food, pharmaceutical, medical equipment, daily chemicals, automobiles, electronic components, stationery and other industries. It can also test the sealing performance of the test piece after the drop and pressure test.
Test principle:
By evacuating the vacuum chamber, the sample immersed in water will have an internal and external pressure difference, and the gas escape in the sample will be observed to determine the sealing performance of the sample; by evacuating the vacuum chamber, the sample will be The internal and external pressure difference is generated, and the shape recovery of the sample after the expansion of the sample and the release of the vacuum are observed, so as to judge the sealing performance of the sample. 6.
