Abstract
A collapsed bag of unitary construction is made of supple polymeric material, having first and second opposed contiguous flat sidewalls joined at edges and at the bottom but free or with user-releasable weakening at upper edges. The upper edges define a bag mouth. Appropriately situated graspable points at or near bag edges allow the sidewalls to be tensioned or snapped in opposing directions thereby causing the interlayer cling, to which supple polymeric bags are renownedly susceptible, to be readily disrupted for the full distance of contact between the tensioning points and thus for virtually the entirety of the bag mouth to be opened.
