ABSTRACT A heat sealable double wall bag for the controlled atmosphere packaging of fresh meat, the bag having inner and outer polymeric walls, the outer wall comprising a polymeric film having gas barrier properties so that a controlled atmosphere is maintained within the bag once the bag has been heat sealed, and the inner wall serving to protect the outer wall from being punctured by bones in meat packaged in the bag, the inner and outer walls being joined over only part of their contacting surfaces so that the atmosphere therebetween can be evacuated when the interior of the bag is evacuated.
