EASILY EXPANDABLE, FLEXIBLE MICROWAVE PACKAGE

A flexible paper microwave package in the form of an easily expandable, nontrapping bag (18) is disclosed including a bottom wall (20) and a top wall (22) interconnected together adjacent their circular outer peripheries (20a,22a) by first and second interconnecting portions (26a,26b). In one preferred form, the top wall (22) is formed from a first portion (22d) having an oval shaped access opening closed by an oval shaped closure portion (22e) interconnected by a seal (40) to the first portion (22d). The bottom and top walls (20,22) expand into an opposing double domed shape as the food product is being popped, puffed, or expanded in the microwave oven. This domed shape of the bottom wall (22) keeps the food product huddled closer together and enhances the bag (18) to rock so maximize gravimetric separation. The bag (18) provides a serving bowl function when the peelable closure seal (40) has been opened providing access to the interior of the bag (18) and specifically to the popped, puffed or expanded food
