A heat-sealable peelable multi-layer laminated polymeric film comprising a polymeric substrate layer having on one side thereof a polymeric heat-sealable peelable layer and having on the opposite side thereof a polymeric shrinkable layer, wherein said shrinkable layer has a degree of shrinkage in a first dimension of about 10-80 % over the temperature range 55 to 100 DEG C, and a ratio of shrinkage at 100 DEG C said first dimension relative to a second, orthogonal dimension in the range of 1:1 to 10:1, and further comprising one or two intermediate layer(s) wherein an intermediate layer is disposed between the substrate layer and the shrinkable layer and/or between the substrate layer and the heat-sealable peelable layer, and one or more layer(s) of an electrically conductive material; and use thereof as packaging for ovenable meals or as a lid on an ovenable container wherein the packaging is self-peeling and self-venturing during a cooking cycle. |
