Abstract A vented bag comprising a front wall, a back wall, and opposite end walls forming an enclosed container. Each of the end walls is comprised of first and second side flaps folded towards one another in an overlapping relationship and being adhered to one another. A pair of end flaps extend inwardly beneath the side flaps at the opposite ends thereof. One of the end walls is provided with a valve member which is positioned between one of the end flaps and the overlapped side flaps. A plurality of venting perforations are formed in at least one of the end walls for providing communication between the interior of the container and the atmosphere. A flat member is secured to the exterior surface of the said one end wall and is positioned over the venting perforations so that air from the interior of the container may escape therefrom outwardly through the vent perforations and outwardly between the end wall and the flap member.
