Abstract
A package for storing or preparing food or other products includes a flexible pouch within which the product can be sealed, and a box' or other container sized to hold the pouch. To seal the product in the pouch, the pouch includes a peelable seal that seals a portion of a first thermoplastic film to a portion of a second thermoplastic film, such films optionally forming walls of the pouch. The package, including the container and the pouch, is configured for beating the sealed product m ″ a microwave oven, in a heated state, pressure inside the pouch increases to expand the pouch, and the container constrains or limits expansion of the pouch in some places but not at an expansion region of the container. A portion of the peelable seal is proximate such region, producing a separation in such peelable sea! portion such that the pouch self-vents through the separation.
