ABSTRACT:
Draw tape bags for carrying trash have a draw tape with ribs extending across the width of the tape, each rib having a thickness greater than the thickness of the tape. The ribs prevent roping of the draw tape handle when a loaded bag is lifted. Roping is prevented because the packing of the ribs is not uniform, thereby creating free space between the ribs. Triangular and cylindrical elements are embedded in the tape to form the ribs.
