Can packaging that has passed seal testing still maintain good seal integrity in high-pressure environments? In practical applications, packaging that has clearly passed seal testing still experiences seal failure. This is because a significant pressure change occurs when moving from a normal atmospheric pressure environment to a high-pressure environment. When external pressure drops rapidly or fluctuates, the internal pressure of the packaging exerts an outward force on the sealing structure; if there are weak points in the packaging, this can lead to seal failure.

How Can Manufacturers Ensure Seal Integrity in High-Pressure Environments?

To effectively address these risks, manufacturers must employ specialized leak detection methods that simulate the pressure differentials packaging faces in real-world high-pressure environments, using sensors to monitor for leaks. Samples should undergo multiple repeatability tests.
