Abstract: An improved bone-guard bag for packaging meats and other foods for longer term preservation during storage and transport, comprising an oxygen and moisture-impermeable outer bag and a puncture-resistant inner bag for preventing bones and other sharp surfaces of the packaged food from penetrating the inner and outer bags to compromise the oxygen and moisture-resistant integrity thereof. Vent means are provided in the bone-guard bag to permit oxygen evacuation, gas flushing, and sealing of both the inner and outer bags simultaneously. The inner bag is secured to the outer bag to allow movement relative to each other, while facilitating insertion of food therein. The outer bag is preferably made from a coextrusion of separate polyethylene and nylon layers bonded together. The inner bag is preferably made from at least two unbonded plies of polyethylene film for increased puncture resistance.
