Abstract
The present disclosure relates to methods for forming reclosable bags with slider zippers which can be used in high pressure pasteurization. In particular, these methods form reclosable bags with a shroud formed over the slider zipper, with a patch or cap for protecting the slider during high pressure pasteurization. When the user tears the shroud from the bag, the patch or cap remains attached to the shroud but releases from the slider. An alternative embodiment forms an air pocket in the shroud to protect the slider.
