Abstract
In order to reduce the percentage of leaks in sealed packages, the sealing jaws contain one or more raised regions that correspond to problem areas for leaks, i.e., adjacent to back seals and folds in the package design. The raised regions are raised approximately 4-20 mils above the regions that seal the normal two layers of material.
