Abstract
A pair of pleats are formed from the same panel on one side of a cylindrical polyethylene bag in which a film of heat sensitive adhesive layer is on the bag layer to form the necessary heat seals. The bag has a lengthwise seam that is formed as an edge of one of the pleats. The other pleat is folded over material from the one panel. The bag is opened by pulling one of the pleats and an edge of the bag with the other pleat between the two pulling points. The pulling forces separate the layers of the one pleat permitting easy access to the bag which is sealed at both ends. The pleats are preferably sealed along the bag length end to end and share a common junction with the one panel from which they are formed.
