Abstract
A multiwall vented bag is provided which includes an inner tube formed of a plastic material. The inner tube has an open end initially in an open position and adapted to receive filling material therein and at least one vent opening formed therein. The bag further includes a strip of material positioned adjacent and attached to a preselected region of the inner tube. The preselected region includes the at least one vent opening of the inner tube. The strip also includes at least one vent opening to allow air to pass from within the inner tube, through both the at least one vent opening of the inner tube and the at least one vent opening of the strip. The bag further includes an outer tube positioned to substantially surround outer surfaces of the inner tube. The outer tube is formed of a porous material that allows air released from within the inner tube to pass out of the bag through porous material of the outer tube. A method of forming and using a vented bag are also included.
