Abstract

PURPOSE: An adhesive tape having a sufficient longitudinal strength and good lateral tearability, prepared by providing adhesive layers on one or both of the surfaces of a laminate film consisting of a biaxially stretched polyolefin film and a specified uniaxially stretched polyolefin film.
CONSTITUTION: An adhesive tape is obtained by laminating (A) a biaxially stretched polyolefin film, longitudinal stretch ratio 3.5W10, lateral stretch ratio 5W10, with (B) a uniaxially stretched polyolefin film which has an orientation degree satisfying the relationship: Ny-Nx≥7×10-3, wherein Ny is a lateral refractive index and Nx is a longitudinal refractive index, and which has a lateral stretch ratio of at least 5 so that the thickness of component A is 3W50% of the entire thickness and that of component B is 97W50% of the entire thickness, coating one or both of the surfaces of this laminated film with a pressure-sensitive adhesive, and cutting the film longitudinally to form tapes with a predetermined width.
