ABSTRACT:
A multi-ply pinch closure bag having an easy-open feature. The bag comprises a multi-ply bag having a front wall, a back wall and a pinch closure at one end, the pinch closure being formed by folding an extension of at least one of the plies of the back wall over the outside of the outermost ply of the front wall and adhesively securing the extension to the outermost ply of the front wall. The outermost ply of the front wall has a longitudinal seam formed by overlapped longitudinal edges of the outermost ply and means for breaking the outermost ply across the longitudinal seam. In a preferred embodiment, the means for breaking the outermost ply across the longitudinal seam comprises two slits, one being adjacent to each edge of the longitudinal seam.
