Abstract: A flexible package for a product includes a resealable closure for resealing one portion of the package to an opposing portion of the package. The resealable closure is formed by applying a layer of pressure-sensitive adhesive on the inner surface of at least one of the opposing portions of the package, and applying a layer of cohesive to the inner surface of both of the opposing portions so that the pressure-sensitive adhesive layer is covered by a layer of cohesive. The pressure-sensitive adhesive has a greater affinity for adhering to the cohesive than to the inner surface of the package. Accordingly, pressure-sensitive adhesive is detached from the inner surface of the package when the opposing portions are pulled apart, and the portions can be resealed by pressing the portions back together to cause the pressure-sensitive adhesive to adhere to the portion from which is was detached.

Abstract: An expandable microwave popcorn package which contains a charge of popcorn kernels suitable for preparation in a microwave oven. The package is formed of front and back panels preferably joined together at the top and bottom ends and at the sides by side panels. The back panel includes two or more sections which are joined along slightly overlapping edges and bonded together by a releasable adhesive, thereby forming lap seam(s). Conversion of the package into a serving vessel is made possible by the releasable nature of the adhesive which allows the lap seam(s) to be disengaged after the popping process is complete. Thus the back panel sections can be detached, and possibly removed, to expose the popcorn within the package. Ideally the heat and steam created by the popping process will diminish the bonding strength of the releasable adhesive thereby enhancing the conversion.
