Abstract
A package is capable of enclosing a food product in two different gaseous atmospheres at different times. Initially, the food product may be packaged in a low oxygen atmosphere in order to prolong the shelf life of the product. When it is time to sell the product for example, it may be desirable to supply oxygen to the food product. In the case of red meats, the oxygenation process causes the meat to turn a bright red color. The package includes a tray covered by a film with a plurality of apertures formed in the tray. The package may be maintained at a pressure below atmospheric pressure. The apertures are covered by a bacterial barrier layer covered by resealable tape which can be removed to allow air ingress and then resealed to protect the integrity of the tray contents.
