Abstract: A laminate and a method for preparing a laminate are provided. The method comprises the steps of providing a container or sheet which comprises a fibrous material, disposing a primer composition onto at least one surface of the container or sheet to form a primer layer on the container or sheet, and also disposing a polymeric liner film onto a surface of the primer layer to form a lined container or sheet. The primer composition comprises at least one sulfopolyester.

Abstract: An open-ended tube comprising walls of a heat-sealable multi-layer polymeric film, wherein said film comprises an outer shrinkable substrate layer and an inner heat-sealable layer, wherein said substrate layer has a degree of shrinkage in the longitudinal dimension of the tube of about 0% to about 50% over the temperature range 55 to 100° C., and a degree of shrinkage in the transverse dimension of the tube of 5 to about 70% over the temperature range 55 to 100° C.; and use thereof in the manufacture of packaging for a container suitable as a receptable for a ready-prepared ovenable meal.

Abstract: 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° C., a ratio of shrinkage at 100° 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.
