Bone-in food packaging article and use field of the invention |
摘要 |
A method for shrink packaging bone-in food masses such as meat cuts is disclosed, A patch bag comprising a thin-walled heat shrinkable thermoplastic film bag and a thick-walled non-heat shrinkable thermoplastic film patch having its inner surface bonded to the bag outer surface is used. Both surfaces have high energy as the sole bonding means and the patch-bag bond strength increases during heat shrinking around the meat mass such that the bag portion adhered to the patch shrinks less than the rest of the bag.
