Abstract
Abstract This invention relates to bags suitable for containing edible components during microwave cooking. The bags may serve as shelf-stable packages for the uncooked edible components as well as containers for the edible components during microwave cooking. The bag comprises two opposing side panels and an inwardly pleated bottom panel between the opposing side panels. Sections of the side panels may be seamed or bonded to sections of the bottom panel so that the inside surface area of the bottom panel is substantially less than the outside surface area of said bottom panel. The side panels are also joined along one side edge and the top edge, leaving an opening on one side. In one embodiment, self close ties are provided by slitting the bag in the area joining the side panels to the bottom panel. In another embodiment, a funnel opening to the bag is provided by means of an appropriately configured seal or bond between the side panels.
