Abstract

Disclosed are flexible plastic tapes each having at least one rounded edge, a method for forming the rounded edge by the application of heat, and an absorbent article provided with such tapes. The edges are rounded to reduce their sharpness in order to reduce the risk of irritation or injury to a wearer of the absorbent article and/or to any person coming into contact with the tapes. The tapes have a thickness not greater than that at which the edge would be sharp if it were not rounded. The tapes are relatively stiff and formed from a plastic material such as polypropylene or polypropylene copolymer.
