Abstract
The self-opening flexible pouch for use in a microwave oven includes a thin plastic film laminated to a paper substrate. The lower portion of the pouch in use is provided with a relatively large susceptor component and the upper portion of the pouch is provided with a relatively small susceptor component. The relatively large susceptor component causes the popcorn kernels contained in the pouch to pop and the relatively small susceptor component causes the pouch to open and allow at least some of the popped popcorn to be released into a paper bag in which the pouch and its contents have been placed. Two methods are disclosed for fabricating the pouch.
