There are several leak test methods used to evaluate the integrity of food packaging.
These include pressure decay tests, vacuum decay tests, bubble emission tests, dye penetration tests, helium mass spectrometry tests, and hydrostatic tests.
Dye penetration tests measure the amount of liquid leaking from the package.
Dye penetration tests are used to measure the amount of liquid leaking from a package. This test is used to detect any leaks in the package and any degradation of the package material. During the test, a dye solution is applied to the package, and the amount of dye that penetrates the package is then measured. The amount of dye that penetrates the package is then used to measure the size of the leak.
The LT series leak tester can be used for this application too.
