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.

Reclosable package with slider zipper shielded for high pressure pasteurization

A flexible zipper intended for use in a package containing powder or other particulate matter. The zipper is designed to be resistant to clogging of the interlocking profiles with powder. This flexible zipper has first and second profiles that interlock in a closed zipper state to define a space therebetween. The space extends in a longitudinal direction, i.e., along the length of the zipper. The bases of both profiles are provided with apertures for enabling powder or other particulate matter trapped in the space between the profiles to pass into the interior volume of a package.
