Abstract
A dual draw tape bag has a front wall and back wall of flexible sheet material joined to each other along edges of the bag. Tubular channels extend along opposed transverse top edges of the front and back walls. The channels define an open mouth for the bag. Each of the channels has openings at the opposite ends of the top edges of the bag. A pair of tapes extend through each of the chanels. One of the ends of each of the tapes is attached to the opposite side edges of the bag beneath the openings in the channels and the other ends of the tapes extend through the respective openings at the other end of the channels so that the tapes cross in the channels, whereby when the tapes are pulled, the top of the bag is drawn tightly together.
