ABSTRACT:
A drawstring is mounted near the open mouth of a plastic bag by a pressure sensitive tape that freely laterally encloses the drawstring except for projecting free ends, the tape being formed or treated so as to be non-sticky with respect to the drawstring. A high speed production method of making the bags comprises the steps of laying a continuous length of drawstring material across a series of spaced bags, applying strips of pressure sensitive tape to each bag to freely laterally enclose the drawstring length there and severing the drawstring length between bags.
