Pinhole Tester (for Aluminum Foil)

Principle of Operation : Leak Test : Air is injected into the package and internally pressurized up to a set pressure and held for a set time. The equipment will automatically detect leakages by monitoring the pressure drop. Additionally, if the package is tested when held under water, you will also see air bubbles from leak points. Even micro leakages which the equipment cannot detect via pressure drop, can be visible under water, making it a very reliable test. Burst Test : Air is injected into the package and internally pressurized until the sample bursts. The max burst pressure is displayed. This is considered as a 360 Seal Strength / Seal Integrity Test. Additionally, you can identify the weakest point of your package as it will fail first. Leak Burst Test : A combination of the above 2 tests. First the Leak Test will happen. If the package FAILS in Leak Test, the test is abandoned. If the package passes the Leak Test, it is automatically subjected to the Burst Test. So you can do 2 test on the same package, while saving time on sample preparation. And of course, you waste less samples.

Pouch Press Tester Test Type : Press till Load Setpoint. Hold till Time Setpoint. In this method, the sample is compressed upto a preset Load. The applied force is held on the pouch for preset time. After the times elapses, the machine returns to the original position.
