Adhesive articles and methods

A polymeric film having a plurality of perforations, which are specially structured and arranged is described. The polymeric film provides a strong, high-tensile strength material that permits hand tearing of the film along a desired tear path, providing a controlled tear propagation line. The polymeric film may also be incorporated into a multi-layer film having cloth-like properties of strength and tear propagation, and is suitable for use various adhesive tape applications. Methods of making the polymeric film are also disclosed.
