Abstract
A flexible, moisture-impervious package for moistened webs includes a pocket portion and a flap section. The pocket portion includes an interior compartment in which the moistened webs are retained. A weakened region provided in a top wall of the pocket portion defines a plug section that is separate from surrounding sections of the top wall to form a dispensing opening through which the moistened webs can be removed. The flap section has a pressure sensitive adhesive layer on an inwardly facing surface, and this adhesive layer is adhered to the top wall in at least the plug section and the wall sections surrounding the plug section.
