Abstract
A stress tearable tape includes an elongated film and a hand tearing arrangement. The film has a non-adhesive surface and an opposed adhesive surface, and defines a longitudinal direction and a transverse direction. The hand tearing arrangement includes a plurality of pinholes formed along the longitudinal direction of the film. With the combination application of internal force, shear tension, compression tension, pinhole arrangement, and material's biaxial structure, and users' habit together, each of the pinholes enables the film being torn by hand with a force starting at one of the pinholes, such that the film is hand tearable at any section in the transverse direction thereof.
