Abstract (en)

[origin: WO0061456A2] An improved microwave popcorn package which contains a charge (16) of popcorn kernels for preparation in a microwave oven. The package is formed of multiple microwave transmissive panels joined together to create a cavity (8) in which the kernels are stored and popped. Preferably one of the panels includes a susceptor (11) for heating the kernels, and the kernels are evenly displaced adjacent substantially the entire surface area of the susceptor. An envelope (16) for containing the unpopped kernels is created from additional microwave transmissive material, or from the panels themselves. The strenght of the envelope is sufficent to contain and protect the kernels during shipping and storage, but the envelope will burst when subjected to the internal pressure created by the kernels during the popping process. One of the package panels is also preferably joined to the package with a releasable adhesive that permits the panel (5) to be removed after the popping process to permit access to the kernels. Preferably the envelope is created with the same material that provides the removable panel, and preferably the envelope isolates any oily ingredients from the remainder of the package during the storage period prior to popping.
