Use
It adopts the test principle of negative pressure method and is suitable for the sealing test of bags, bottles, cans, boxes and other packages. The test can effectively compare and evaluate the sealing technology and sealing performance of the package, and provide a scientific basis for determining the relevant technical indicators. It can also be used to test the sealing performance of certain packages after drop and pressure tests. It is also called a sealing instrument, a sealing tester and a flexible packaging sealing tester.
Test principle
By evacuating the vacuum chamber, the sample immersed in water generates internal and external pressure difference, and observing the gas escape from the sample, so as to determine the sealing performance of the sample; by vacuuming the vacuum chamber, the sample generates internal and external pressure If it is poor, observe the sample shape recovery after the sample expands and releases the vacuum to determine the sealing performance of the sample.
