An end-seal patch bag has a patch which extends more than 50 percent of the total transverse distance around the bag, the patch covering at least a portion of at least one side edge of the bag. A side-seal patch bag has a patch which extends more than 50 percent of the total longitudinal distance around the bag, the patch covering at least a portion of the bottom edge of the bag. For both end-seal and side-seal patch bags, the patch covers at least a portion of each lay-flat side of the bag. The invention includes a process for making these end-seal and side-seal patch bags, as well as packaged products utilizing these patch bags. By providing a patch which covers more than just one lay-flat side of the bag, the use of a second patch can be avoided, together with the inefficiency, alignment, and registration challenges encountered if more than one patch is applied to the bag.

Patch bag having wrap-around patch

Disclosed is an oriented, heat shrinkable, thermoplastic vacuum bag having a protective heat shrinkable reverse printed patch attached thereto, thereby protecting the bag from puncture by sharp protruding bones in bone-in cuts of meat which are vacuum packaged within the bags while simultaneously providing desired graphics protected from abrasion. The protection is especially directed to prevention destruction of the desired graphics when used on bags for packaging bone-in cuts of both fresh and smoked or processed meat. The reverse trap printed bag produced by this method is also disclosed.
