Abstract
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.
