Abstract: Disclosed are apparatus and methods for testing packaging and/or materials (e.g., package integrity and/or seal strength testing) wherein one or more coatings are applied to the one or more surfaces of the packaging and/or materials prior to testing. In one aspect of the present invention, when applied to a permeable package or a portion thereof, the coating transforms the package, or portion thereof, to an impermeable package or a package having impermeable portions thereof. After such transformation, a wider variety of testing methods including quantitative test methods may be used to test such permeable packages including standard burst seal strength, dye seal integrity, and package integrity tests. Furthermore, application of one or more coatings to the permeable package and/or material prior to testing enhances the sensitivity and repeatability of the test methods allowing for more reliable seal strength measurements and consistent detection of small defects (e.g., pinholes).

Abstract: The present invention provides a foil laminate pouch with an attached spreader having an arcuate edge affixed to the pouch to allow the contents of the pouch to be readily spread over the area to which the contents are to be applied.
