Abstract: A bag for carrying corn kernels for popping in a microwave oven. The bag has front, back, and gusseted side panels and carries a susceptor for receiving microwave energy and heating the corn for popping. In general, the bag is of the single gusset tube type with a V-shaped bottom. The bag has winged end constructions where the seals are entirely internal, in a linear zone or band that extends from side-to-side, (i.e. transversely of the bag length). The top seal is not as strong as the bottom seal, so as to permit top venting. In the winged construction the front and back panel centers are adhered together and gusset folds are secured to an adjacent front or back panel. Upon bag expansion the bag has an increased internal volume for its size, minimizes tilting and maximizes susceptor/oven floor contact and can be set upright on the bottom end winged construction. This bag structure provides for more complete popping and for a more pleasing pillow shape for the bag.
