The system works by applying vacuum pressure inside a transparent, water-filled chamber. If the packaging is compromised, bubbles appear, indicating a leak. This allows for fast, visual, and reliable testing of various packaging formats.
What is a Vacuum Leak Tester?
A Vacuum Leak Tester is used to identify seal failures in packaging. The product is submerged in water, and vacuum is applied. If air escapes, it forms visible bubbles, confirming a leak.
This method is:
Easy to perform
Non-destructive for rigid packages
Ideal for routine QA checks
Compliant with standards like ASTM D3078 and ISO 11607-1
