Abstract
A multiwall commodity bag comprising a sealed plastic tube having a longitudinal seam formed by overlapping margins sealed together by two spaced seals to provide a channel. The overlapping margins are formed with openings only at the opposite ends of the channel, one of the openings being formed in one of the overlapping tube margins at one end of the channel and providing communication between the interior of the tube and the channel to permit escape of air through the tube, another of the openings being formed in the other overlapping tube margin at the opposite end of the channel and providing communication between the interior of the channel and the exterior of the tube. The size and number of openings are such as to permit venting of the tube while inhibiting flow of commodity into the channel or admission of external contaminants into the channel.
