Abstract
The disclosure relates to a semi-soft cap or patch which is secured by adhesive to a slider on a zipper in a reclosable package. This cap or patch prevents the slider from puncturing the web or film of the bag during high pressure pasteurization. Further, the cap or patch is secured to a tear-away header which is formed as a shroud over the zipper. This allows the user to tear off the header which likewise removes the cap or patch from the slider. The header, with the cap or patch still attached thereto, can thereafter be disposed of as a single piece.
