Title
(EN) STRESS TEARABLE TAPE
(FR) BANDE DÉCHIRABLE PAR CONTRAINTE
Abstract
(EN) 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 1he film is hand tearable at any section in the transverse direction thereof,
(FR) L'invention concerne une bande déchirable par contrainte comprenant un film allongé et un système de déchirure à la main. Le film possède une surface non adhésive et une surface adhésive opposée, et définit une direction longitudinale et une direction transversale. Le système de déchirure à la main comprend une pluralité de trous d'épingle formés le long de la direction longitudinale du film. Grâce à l'application combinée de la force interne, de la tension de cisaillement, de la tension de compression, du système de trous d'épingle et de la structure biaxiale du matériau, et de l'habitude des utilisateurs, chacun des trous d'épingle permet au film d'être déchiré à la main avec une force commençant au niveau de l'un des trous d'épingle, de sorte que le film est déchiré à la main au niveau de n'importe quelle section dans la direction transversale de celui-ci.
