<p>A bag closure and a method of making in which a folded seam is formed about the mouth of the bag with a draw-cord or draw-tape disposed in the seam. The material forming the seam is on one or both sides of the cord or tape provided with a row of slits or holes. When holes are employed, alternate ones are connected by incisions. The rows of slits or holes, when on both sides of a seam, are staggered relative to each other and the ends thereof overlap. When the cord or tape is drawn up to close the bag, the mouth of the bag will fold up as in the case of an eyelet type closure with the fold lines occurring in about the middle of the length of a slit or about halfway between each pair of holes connected by an incision.</p> |
