Abstract
A paper bag is described comprising a pair of face panels, one of which may be narrower than the other, joined by centrally extending gussets. The bottom and top of the bag are sealed, the bottom with a permanent seal and the top with a rupturable seal formed from thermoplastic adhesive so that the top can open to form a vent when products, e.g., foods, are heated within the bag in a microwave oven. The strong bottom seal may consist of diagonal seals that extend diagonally from the center of the bag toward the side edge. One or more temporary transverse seals can be provided near the center of the bag.
