Abstract: A package structure for microwave popping of popcorn comprises a conventional tubular body bag wherein a closed bottom end minor length portion is folded over onto a major length portion defining a combined unpopped popcorn space and popped popcorn chamber, and a separator screen is secured across the body between the minor and major length portions at the line along which the minor portion is folded over onto the major portion. The separator screen has screen holes for shaking out separation of spent unpopped popcorn kernels from popped popcorn within the expanded bag chamber into the pocket under the separator screen. A rim about the screen holes blocks return of the spent unpopped kernels from the pocket to the popped popcorn chamber.
