Pouch Seal Integrity Testing
The Sepha Multi-Q with Flexible Membrane is a non-destructive pouch seal integrity testing solution. It is a tool-less machine that uses an innovative hybrid membrane in combination with vacuum decay to detect leaks, weak seals and micron holes down to 15µm* in flexible and semi-flexible packaging.
Typical applications include non-porous pouches, sachets, bags and stick packs that contain powder or solid components.
The test method utilizes the PDA approved ASTM F2338-09 standard test method that prefers non-destructive leak test methods. The system can also form part of 21 CFR Part 11 compliance. The standard flexible membrane has a tests area of 250 x 150mm but custom sizes are available on request. The main benefit is that no further tooling is required for different size packages as the membrane will adjust to the pack that is being tested, in line with the appropriate test method. Multiple packs of the same package can be tested at the same time.
The Multi-Q with flexible membrane is a quick and deterministic pouch seal integrity testing method that give a pass or fail result within as little as 15 seconds.

How does vacuum decay testing work?
To conduct a vacuum decay test, the flexible packaging is placed in the flexible membrane which is evacuated to a predetermined level of vacuum. After reaching the pre-set vacuum, a sensor measures the vacuum level over a predetermined time.
If the integrity of the flexible packaging under test has been compromised (it has a leak), there will be a rise in pressure measured inside the flexible membrane. This will result in a) a gross leak, if the vacuum doesn’t reach the pre-set vacuum level; b) a medium leak, if the vacuum level drops below a pre-set vacuum level during the test or c) a decay or micron leak, if the vacuum level exceeds the decay limit during the test time.Learn more
