Vacuum Leak Testing for Package Integrity: Labthink’s Solutions and Best Practices

January 20th, 2026 No comments

A vacuum leak test is a non-destructive quality control procedure used to identify and locate leaks in sealed packages or containers. The test involves placing the packaged item inside a sealed chamber and evacuating the air to create a vacuum. If a leak is present, air or gas will escape from the package into the chamber. This is detected either by a pressure rise in the evacuated chamber in the Vacuum Decay method setup, or by observing bubbles escaping from the package while submerged in a water bath in the Bubble Emission method setup. This method is essential for verifying the seal integrity of packaging, ensuring it protects the contents from environmental factors. The reliability of this test depends on the use of calibrated precision test instruments to apply and monitor the vacuum level accurately. It is widely applied in industries like food, pharmaceuticals, and medical devices to prevent contamination and preserve product shelf life.
