Abstract
A method and apparatus for detecting leaks in blister packages wherein a package is supported with a support chamber and a flexible and imperforate bladder is placed over the package after which at least a partial vacuum pressure is applied and a measure made to determine if any leakage is detected while an image of the bladder is detected, such as by a camera, with the image being used to provide a visual indication of the location of a failure in the blister package.
