Multilayered sheet material, a method for producing said material and a package comprising said material are provided. The multilayered material and package produced therefrom have apertures sealed with an extrudable hot melt material which conveys moisture barrier properties and is adapted to soften and permit venting of vapor generated in the package prior to distortion of the package. The packages are adapted particularly for use as containers or as components thereof when used in heating or cooking of foods in microwave ovens.
