A package for use in microwave ovens is disclosed in its preferred form of a flexible, tubular bag (18) including expandable side walls (26) interconnected between bottom and top walls (20, 22). The side walls (26) include pleats (26a, 26b, 26c, 26d) which are folded in a collapsed condition of the bag (18) and expand due to internal expansion forces generated by the popping of kernels and the creation of water vapor. The openable end (28) opposite the permanent end wall (24) of the bag (18) is formed by V-shaped adhesive strips (34, 36) located between the bottom and top walls (20, 22) and the pleats (26a, 26b, 26c, 26d). Large, triangular shaped, unsealed areas (38a, 38b, 38c, 38d) formed and defined by the bottom, top and side walls (20, 22, 26) between the free ends thereof and the adhesive strips (34, 36) function as flaps separated from the interior of the bag (18) by the adhesive strips (34, 36) and maintained at a cooler surface temperature than the remainder of the bag (18) for grasping by the consumer to remove the bag (18) from the microwave oven and to peel the adhesive strips (34, 36) apart to open the bag (18) after popping.
