A dispensable multilayer film having alternating layers of a ductile material, a brittle material, and optionally an intermediate layer. The film has excellent strength in its longitudinal and transverse directions but can be transversely cut by forces of less than 9 Newtons on the cutters of commercially available table top tape dispensers. At least one surface of the sheet material can be coated with a functional material.
