ABSTRACT OF THE DISCLOSURE A recyclable tape reel which is a one-piece, integrally molded member, including: a lower, planar, continuous flange; a central hub connected to the lower flange; an upper, planar continuous flange attached to the hub; and a reel spring molded integrally of the upper end of the tape reel. A leader clip can be formed separately and assembled on the hub, or can be integrally molded of the hub. The leader clip and reel spring can be formed together as one piece and attached to the hub, or they can be molded together integrally of the hub. The dust door can be removed but the dust door metal spring remains in the cassette. However, the cassette base includes an opening to allow the metal dust door to fall out of the cassette spring. The cassette base includes openings to disengage the leader clip from outside the tape cassette, thereby allowing the tape and leader to be removed from the cassette without opening the cassette. All parts of the cassette, except the dust door spring and tape, are made of the same plastic material which can be recycled as one piece once the tape and dust door spring are removed without opening the tape cassette. The thickness of the cassette walls is less than conventional, but supports are added at the walls to reinforce the cassette. Also, the supports contain radial and vertical movement of the tape reels.
