Abstract
Laminated blanks for forming moisture-resistant packages are produced from a substrate, such as cardboard. A continuous web of substrate is perforated and fold lines formed. Perforated regions are stripped therefrom prior to laminating with moisture-resistant heat-sealable sheeting using a heat-weakenable laminating material. Thereafter, a multitude of rows of individual blanks are profiled by die-cutting the laminated web. The blanks have unsupported sheeting regions disposed along an edge portion of the substrate which provide membranes or webs that are adapted for sealing to another portion of the laminated sheeting to form a continuous barrier that may be used to prevent wicking in an erected package.
