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. Separation lines, along which the structural integrity of the package is relatively weak, may also be used in conjunction with a lap seam to enhance the conversion while avoiding manufacturing problems associated with multiple lap seams.
