ABSTRACT:
A flat bag closure (17) of the type having at its edge a V-notch (12) which communicates at its base with a bag neck gripping aperture (14). The closure is made of a non-frangible material so that it can fold along an axis (20) aligned with said notch and said aperture without breaking. The closure thus can be repeatedly bent along such axis to facilitate repeated insertion and removal of a twisted poly bag's neck (36) into and from the aperture. The axis may contain a hinge formed by perforations (19, 24, 26, 28, 30), a concavity (22), or slits (32, 34) to facilitate bending.
