The hot sealing performance of packaging materials is the main parameter to evaluate the packaging ability of materials. It includes hot tack and ultimate strength. Hot tack has been used to check the strength of peeling the heat-sealed part shortly after heat sealing while it’s not cold. Ultimate strength has been used to check […]

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

The product tears and breaks due to external force during storage and transportation. Sufficient tear resistance can reduce tearing and prevent leakage. SLD-01 Tear Tester: complies with the Elmendorf method and is suitable for tear strength testing of films, laminated films, foils, paper and cardboard. The tearing tester determinates the average force to propagate tearing
