A microwavable package incorporating controlled venting, including a bag formed of a series of walls, the front, back, side gusseted, and bottom walls, with the walls being of the type formed of a series of laminates constructed of at least a pair of laminar materials, forming at least an inner and outer layer for the structured bag, a vent chamber provided between select of said laminates to afford a controlled venting of the cooking generated pressure and steam from the interior of the bag to its exterior during a cooking process, at least one vent passage provided through the inner laminar material within the region of the disposed vent chamber, said vent chamber extending to the exterior of the bag, whereby during the heating of an item within the bag its generated pressure and steam enters into the vent chamber by way of the vent passage and is released exteriorly of the bag during cooking, while maintaining the integrity of the package and its upper seal during the process.

A ventable, sealed package containing food to be microwave heated for consumption, said package being capable of allowing said food to be heated in a microwave oven while in said package, said package comprising a bag, said bag comprising a series of walls comprising longitudinally oriented front, back and inwardly folded gusseted side panels, and a bottom panel providing lower closure for the package, and a top sealed edge sealing upper portions of said front and back panels and gusseted side panels together to seal said food between the panels which food is contained therein, said bag and thus each of said panels being formed from the same continuous blank and comprising a laminated sheet comprising a heat sealable and non-wicking innermost layer, an imperforate moisture barrier intermediate layer and an imperforate outer layer, said innermost heat sealable layer having at least one array of a plurality of slits through its thickness, said slits oriented relative to each other longitudinally along the bag between the bottom panel and the top sealed edge at at least one location in at least one of said longitudinally oriented panels, said innermost layer and intermediate layer being laminated to each other over substantially the whole area of each of said longitudinally oriented panels and said bottom panel except in at least one narrow unlaminated area relative to the area of said longitudinally oriented panels which narrow area overlies the array of slits, there being one narrow area for each array of slits, said array of slits forming vent passages allowing gaseous communication from inside said bag to said unlaminated area between said innermost and intermediate layers, said unlaminated area extending longitudinally to said top sealed edge such that said unlaminated area forms at least one vertical channel which opens exteriorly of the bag at the top sealed edge allowing gaseous communication from said vent channel to the exterior of the bag, said top sealed edge comprising opposing portions of said innermost layers of said vertically oriented panels being sealed together to completely seal access to the interior of the bag from the exterior at the top, said at least one array of vent passage slits and said at least one channel between said innermost and intermediate layers dimensioned such that controlled venting of said bag occurs during microwave heating with any internally generated pressure and steam passing through said vent passages into said at least one vent channel between said innermost and intermediate layers and out through said bag at the top sealed edge with said top sealed edge between said opposed sealed innermost layers remaining completely closed.
