Disclosed is a bag arrangement and packaging method for packaging bone-in cuts of meat using two bags 12,14 to provide a double wall of film surrounding the cut of meat for bone puncture resistance. Both bags 12,14 are bottom sealed bags formed of a heat shrink film, the inner bag 12 has an interrupted bottom seal to provide an opening 20 for venting air between the bags and the outer bag 14 has a continuous bottom seal. The outer bag is longer than the inner bag so the outer bag can be closed without involving any portion of the inner bag in the closure. The bone-in cut of meat is inserted first into the first bag 12 and then the first bag and its contents are inserted into the second bag 14, the bags are evacuated and then the outer bag 14 is closed. Outer bag 14 is formed of a multilayer oxygen and moisture barrier film. The bottom of each bag extends in a convex arc across the flat width of the bag, the arc of inner bag 12 being the less convex. |
