Overwrapping and modified-atmosphere packaging (MAP) protect the freshness of meat, poultry and seafood and extend the shelf life. Overwrapping continues to dominate, particularly for store-packaged and case-ready beef, but MAP enjoys a solid position. MAP is seen for value-added items such as meatballs and an array of case-ready products, especially poultry. In fact, a casual study of refrigerated cases at grocery stores shows MAP appears to have captured the ground turkey segment.
It’s not surprising, really, since MAP can add several days — even weeks — of shelf life. In addition, hermetic seals eliminate leaky packages, a consumer turn-off, and printed film offers the potential for strengthening brand identity with enhanced graphics.
