The package for use in a microwave oven includes an expandable paper bag transparent to microwave energy having a susceptor path fixedly associated with one side wall thereof and a patch of microwave reflective material fixedly associated with the opposite side wall, so that when the package is placed in a microwave oven with the susceptor patch lowermost and the microwave reflective patch uppermost, the upper patch reflects at least some microwave energy so as to reduce the amount of microwave bombardment in the upper regions of the paper bag. In this way, the kernels of corn that have been popped and underlie the upper patch are less likely to be scorched.

A single cell bag containing therein popcorn kernels to be popped in a microwave oven, the bag being of flexible material generally transparent to microwave energy, the bag comprising lower and upper face walls, at least some of said kernels initially resting on said lower face wall, lower and upper side pleats, said lower face wall extending between the lower edges of said lower pleats and said upper face wall extending between the upper edges of said upper pleats, a first patch integrally associated with said lower face wall for converting at least some microwave energy to thermal energy, and a second patch integrally associated with said upper face wall for reflecting at least some microwave energy and said second patch being movable upwardly with said upper face wall as said pleats permit said bag to expand upwardly due to the popping of at least some of said kernels at a lower level in said bag where the temperature is relatively high due to heat supplied by said first patch, at least some of the popped kernels rising to an upper level where the temperature is lower due to the reflective action of said second patch.
