Vacuum decay is a container integrity test method taking advantage of the fundamental physical properties. This test method which was proved over decades has been improved with the advancement of technology.
Vacuum decay has been substantiated as one of the most practical and sensitive vacuum-based leak detection method. This test gives a reliable, reproducible, repeatable and accurate quantitative result with a pass or fail determination.
Packages can be non-destructively evaluated using the VeriPac inspection method which is based on vacuum decay technology. Package types include filled and sealed rigid, semi-rigid and flexible packaging made of non-porous or porous materials. This vacuum decay method developed by PTI’s VeriPac instruments are capable of detecting leaks in the single digit micron range.
