ABSTRACT:
Normally tacky, pressure-sensitive adhesive tapes which are soft, pliable, conformable, and heat sealable are provided. The tapes have a backing of a substantially untensilized, tough, ductile film, the film being a blend of crystalline isotactic polypropylene and a compatible ethylene-based polymer, and a normally tacky, pressure-sensitive adhesive on one side of the film. The films have a longitudinal secant modulus of less than 3700 kg/cm.sup.2, a transverse secant modulus of less than 3700 kg/cm.sup.2, a longitudinal elastic modulus of less than 5200 kg/cm.sup.2, a transverse elastic modulus of less than 5200 kg/cm.sup.2, a longitudinal stiffness of less than 1.7, and a transverse stiffness of less than 3.0.
