Abstract: A self-venting cover for a heatable food package comprises a sheet of film having a slit formed therein to permit the passage of steam therethrough. A label is secured to the film for controlling the flow of steam through the opening. The label includes a sheet of material having a first region secured to the film in an area remote from the slit and having a second elongated region covering the slit. The elongated region is only partially secured to the film and forms a vent passage between the unsecured portion of the elongated region and the film itself, which vent passage extends from the slit towards the periphery of the label to permit controlled venting of steam from the opening. The elongated region of the label is relatively narrow and the first region is relatively wide and is located spaced from the opening.
