Force Decay Leak Test
The VeriPac 410 inspection system uses force decay technology for non-destructive seal and leak detection for blister packs, sachets, and pouches with low headspace.
The VeriPac 410 inspection technology platform combines the sensitivity and reliability of PTI’s vacuum decay technology while introducing a force-based measurement to enhance results. The 410’s force decay technology is capable of measuring force from the surface deflection of a package during a normal vacuum based test cycle. This force measurement of the package surface allows the VeriPac 410 to identify which package is defective while also being able to leak test packages with minimal headspace.
The test system uses a nested tooling to position the package in a consistent location and to limit the unmeasured expansion of the package being tested. Once the test is initiated, a vacuum is drawn on the test chamber causing the package to expand within the chamber. Vacuum levels are monitored during the test cycle to evaluate the package using the ASTM F2338 vacuum decay leak test method. The expansion of the package being tested applies force to the VeriPac force measurement system.
Multiple packages can be tested per test cycle with the force decay measurement system identifying if there any defective packages. Defective packages show a decay in the expansion force or vacuum level during the test cycle. The location of the defective package or cavity is identified. Force decay is the most effective technology to deploy when multi-cavity package formats are being tested.
