How can a Vacuum Leak Tester Help in Testing Seal Quality?

Seal integrity holds a lot of importance in the packaging industry. The seal quality, the adhesive used to seal a package or the sealing process, everything matters when we discuss packaging quality. One should know whether the seal, the bond made between the two seal materials is ok or not. Poor-quality seals can lead to many scenarios like, leakage of content, bursting out of the packaging material, and other damage related to the product inside and packaging material. Hence, it is very crucial to check the integrity of the seals by checking the behaviour of the packet under changing environmental conditions. Out of all external climates, Vacuum changes are the most important factor that affects the seal quality. Let us learn more about how Vacuum Leak Tester can help in testing the seal quality.

How do Vacuum changes affect the seal strength?
The truth is that the vacuum itself might not directly affect the quality of the seal but it plays a vital role in revealing the leaks, holes, or cracks in the seal or packet.

1. If your seal quality is perfect and has no holes or cracks, it will have a equal amount of pressure on both the sides. Now when we apply vacuum using the Vacuum Leak Detector, it generates a high amount of difference in pressure across the seal, which puts high level of stress on the seal bond. This is the moment of truth, which discloses the quality of seal. If its weak or has any defect it will be easily detected that might go unnoticed in normal conditions.
2. When we test the seal sample in vacuumed condition, it sometime expand and contracts the material of the seal adhesive, which in return creates the flaws to enhance and come in to notice easily and can be detected.
3. Vacuum leak testers for packaging, is used to find out the leaks or any hole in the product and not create them. If there is any hole, even the tiniest one, the vacuum created develops a pressure that pushes the seal points to burst open or the air created inside will leak out from the holes. This point of failure will help the manufacturer to identify the quality of their packaging material or the adhesive used for the seals.
