Abstract
One or more patches adhered to a bag have a first-patch-overhang-region and a second-patch-overhang-region, wherein at least a portion of said first-patch-overhang-region is adhered to said second-patch-overhang-region. The overhang regions are preferably present on separate patches adhered to the bag. The patches can extend completely around the bag, eliminating uncovered regions, thereby providing protection against puncture by a bone-in meat product packaged within the bag. This “full width patch bag” has been discovered to be particularly beneficial in reducing punctures in the packaging of whole bone-in pork loins. Other bag embodiments without patch overhangs are also disclosed, for solving the bone puncture problem by providing alternative full width patch bags.
