Abstract
An air-exhausting flexible plastic bag is provided which comprises a flexible film defining the bag, a closure means for air-tightly closing the bag, and a one-way air valve for exhausting air from the bag when closed. The valve uses the flexible film of the bag as a flapper, which seats against a backing member adhered to an inner surface of the flexible film except at regions of the film surrounding venting holes therein.
