Pressure-sensitive adhesive tape having improved toughness

Abstract

Pressure-sensitive adhesive tapes which have improved toughness for use as diaper closure tapes are provided. The tapes have a backing of a substantially untensilized, tough, ductile film that is a blend of crystalline isotactic polypropylene and a compatible flexible polymer, i.e. a polymer having a flexural modulus lower than said crystalline isotactic polypropylene to increase the toughness of the film, and a coating of a pressure-sensitive adhesive on one side of the film.
