Abstract:
A film according to the present invention, there is provided a multi-layer laminated polymeric film comprising a substrate layer having on one side thereof a heat-sealable peelable layer and having on the opposite side thereof a 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° C., and a ratio of shrinkage at 100° C. said first dimension relative to a second, orthogonal dimension in the range of 1:1 to 1:1; a process for making the same; and the use of said film as a lid for a container, particularly a container used for packaging ready-prepared ovenable meals.
