Leak Testing of Flexible Packaging - Combining image processing and leak testing

Flexible packaging such as flow packs, doy packs, spouts and blister packaging places high demands on reliable leak detection. The solution presented combines optical inspection with leak testing, enabling both rapid detection of gross leaks using image processing and artificial intelligence and quantitative evaluation of smaller leaks. Depending on the application, hole sizes down to approximately 10 µm can be detected, while typical sealing defects can also be identified. The Application Note presents both a compact benchtop solution for laboratory and sample testing and an inline concept for automated end-of-line inspection at rates of several hundred parts per minute.
