Purpose: This study was designed to investigate the relationship between the peel force required to remove the medical adhesive tapes and the angle of peel. Method : Three kinds of adhesive tapes to fix gauze, 25 mm in width and 125 mm in length (Tape A, B and C) were stuck on a bakelite board for 30 minutes, and then removed while the peel forces were recorded. Peel force measurements were obtained at 30°, 60°, 90°, 120°, 150°, and 170°. Tape A was rayon non-woven fabric coated with an acrylic adhesive. Tape B was poly vinyl chloride tape coated with a rubber adhesive. Tape C was polyethylene film coated with an acrylic adhesive. Results: For all tapes used, the maximal peel force occurred at peel angle 30°. The peel forces at 30° were three times the minimal peel forces which were observed at 90° to 120° for Tape A, 120° to 170° for Tape B, and 90° to 150° for Tape C. Conclusion : These findings suggest that a peel angle near 120° might be commonly good for less irritation.
