ABSTRACT:
A process and apparatus for packaging articles, particularly fresh meat pieces, in a substantially gas impermeable flexible container. In the packaging of fresh meat, the process enables the meat to be held for extended periods of time, and yet the natural color of fresh meat is maintained and the bacteria growth does not exceed limits which would cause the meat to be considered inedible. The fresh meat is first placed in an open, substantially gas impermeable flexible container. Hollow passage defining means are inserted through the open portion of the flexible container, and while the top is being temporarily sealed, the container is vacuumized for removing substantially all the air and oxygen therefrom. After the air is removed, carbon dioxide is added to the container, the concentration of the carbon dioxide being such as to avoid significant bacterial growth on or in the meat over extended periods of time, while avoiding discoloration of the meat. Thereafter, the passage defining means are removed from the container, and the container is sealed, preferably by heat sealing, to prevent the egress of carbon dioxide therefrom and the ingress of air thereinto.
