LAYER OF ADHESIVE ON POLYPROPYLENE BACKING

摘要

A tape comprising a polypropylene backing coated on one surface with an adhesive. The backing is biaxially oriented to provide a secant modulus of elasticity measured at one percent elongation in its longitudinal direction of at least about 25x105 kilopascals, will break before it can be stretched in its longitudinal direction by about 55 percent and can be transversely cut by forces of less than about 13 newtons on the cutters of commercially available tabletop tape dispensers.
