Several products we use on a daily basis get packaged in foil pouches, some of these include
- Medical Devices
- Testing Strips
- Infant Nutrition
Foil pouches can vary in size, coating material, contents and testing requirements. Container tightness is generally described by a diameter of a sharp-edged hole-size/defect in microns. For help determining an appropriate tightness specification please see our CCIT Services article.
Most pouch tightness specifications range from 5 to 50-micron sharp edged defect size. For these applications we recommend ATC’s VE2 or ME4 micro-flow vacuum tester. Combined with a customer test chamber you can be sure you have a reliable and cost effective test method.
