Easily expandable, nontrapping, flexible paper, 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 ( 20 a , 22 a) by first and second interconnection portions ( 26 a , 26 b). In one preferred form, the top wall ( 22 ) is formed from a first portion ( 22 d) having a generally oval shaped access opening closed by a generally oval shaped closure portion ( 22 e) interconnected by a wet adhesive seal ( 40 ) to the first portion ( 22 d). In a preferred form, the wet adhesive seal ( 40 ) is formed by a plurality of spaced, parallel bands ( 400, 401, 402 ) defining a plurality of spaced, parallel spaces therebetween for resisting any leakage from the interior of the bag ( 18 ) through the seal ( 40 ). 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 ( 20 ) keeps the food product huddled closer together and enhances the bag ( 18 ) to rock to maximize gravimetric separation. The bag ( 18 ) provides a serving bowl function when the closure seal ( 40 ) has been opened providing access to the interior of the bag ( 18 ) and specifically to the popped, puffed or expanded food product located therein. An extension ( 42 ) integrally extends from the closure portion ( 22 e) along the major axis of the generally oval shape. First and second pairs of extensions ( 54 ) integrally extend from diametric opposite sides of the bottom and top walls ( 20,22 ) and along the major axis of the generally oval shape. The closure portion ( 22 e) includes a peel element ( 90 ) formed therein which breaks away during opening. The interconnection portion ( 26 a) includes predictable, preferential venting at locations remote from the extensions ( 42, 54 ).
