Abstract
Disclosed is an oriented, heat shrinkable, thermoplastic vacuum bag having a protective heat shrinkable patch attached thereto such that said heat shrinkable patch covers substantially all area exposed to bone, thereby protecting the bag from puncture by sharp protruding bones in bone-in cuts of meat which are vacuum packaged within the bags. The protection is especially directed to prevention of bag puncture by, bone-in cuts of both fresh and smoked or processed meat. The bag produced by this method is also disclosed.
