摘要： A method for providing sealed internal labels for vacuum skin packages and the like is disclosed. Labels with a heat sealable printed surface are placed on the trayed product prior to entering a vacuum skin packaging chamber. In the chamber the covering film is heated to its sealing temperature before it is applied by differential air pressure to the product and tray. The label seals to the interior surface of the covering film and is protected from being defaced during handling. Furthermore moisture and juices from the product will not discolor the label as it is sealed on its printed surface to the covering film. The package produced is intended for the display case in a retail supermarket.
