Qualipak 770

The Qualitek 770 is based on the force decay test principle for flexible package testing.
The test principle is a vacuum applied to the chamber, which encourages the pack to inflate. The package infants until the control vacuum is achieved, creating a force onto the load cells. Once the control vacuum has been reached, the chamber is isolated for period of time to allow the package to stabilize. The force is then monitored for a decay. If the force decays at a rate greater than expected, the instrument fails (red light) the part. If the force does not decay then the instrument passes, Accepts (green light) the part.
