Packaging Leak Tester Overview

The packaging leak tester is suitable for the sealing test of soft packaging parts and plastic bottles and cans in the food, pharmaceutical, daily chemical and other industries. The test can effectively compare and evaluate the sealing process and sealing performance of the flexible package, and provide a scientific basis for determining the relevant technical requirements. It can also test the sealing performance of the test piece after dropping and pressure resistance. Principle: By evacuating the vacuum chamber, the sample immersed in water produces a pressure difference between the inside and outside, and the gas escape in the sample is observed to determine the sealing performance of the sample; by evacuating the vacuum chamber, the sample is produced. The internal and external pressure difference is observed, 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.
