Abstract: A pressure flap for eliminating slack in a tape cassette. The pressure flap includes a body portion having a tape contact edge at a first end thereof, and a fold line at a second end thereof. The body portion is bowed along a line extending generally parallel to the fold line. The pressure flap also includes a folded portion extending contiguously from the fold line of the body portion at a predetermined angle. The body portion includes a pair of opposed lateral edges secured to a pair of opposed sides of the folded portion. In a preferred embodiment, the pressure flap is fabricated from carbon-filled, high-density polyethylene, and the opposed sides of the folded portion are fused to the lateral edges of the body portion during fabrication of the pressure flap.
