Abstract
Abstract Several package embodiments are illustrated. In two embodiments, a panel constitutes an extension of one wall of a flexible bag having therein a susceptor pad. Only a portion of the panel is adhesively secured to the end wall, there being a second portion constituting a flap that extends freely from the bag so that the flap remains quite cool when the package is heated in a microwave oven, even though the bag itself becomes quite hot. The third embodiment involves an individual panel having one portion thereof adhesively secured to an end wall of the bag and a second portion constituting a flap that extends upwardly from the end wall so that the flap remains relatively cool and can be grapsed with a person's fingers to effect safe handling of the bag after being heated in the microwave oven.
