Abstract
A bag structure and the method of forming wherein the bag is formed of a thin film material with wall panels and an openable bag top having pressure closable rib and groove profile fasteners at the top and upwardly extending pull flanges with a fold formed at the top of one of the wall panels and extending downwardly to attach to one of the fasteners and the flange of that fastener attached directly to the fastener so that the pull flange can apply an opening force directly to the fastener and so that the side wall and the fold can expand and move outwardly without applying a direct force to the fastener which would tend to open the fastener.
