Patent

CA 2420886

A teartape (10) comprises a base film (12) of monoaxially oriented polypropylene, having on an upper side thereof a coating (14) of release agent, and having on a lower side thereof a coating of pressure sensitive adhesive (16). A printed image (18), in particular a fiscal indicium, is formed on the base film (12), which image extends substantially for the full width of the tape (10). A stripe (20) is printed on the base film (12), which stripe is narrower than the tape (10). The base film, adhesive (16) and release layer (14) are transparent so that the image (18) and strip (20) may be viewed through the tape. The image (10) is preferably complex and multicoloured, so as to be difficult to reproduce by a would-be counterfeiter.

La présente invention concerne une bande de déchirure (10) constituée d'un film de base (12) en polypropylène à orientation uniaxiale. Sa face supérieure est enduite (14) d'un agent de décollement, et sa face inférieure d'une matière autocollante (16). Une image imprimée (18) telle qu'une marque fiscale, réalisée sur le film de base (12), occupe sensiblement toute la largeur de la bande (10). Un filet (20) plus étroit que la bande (10) est imprimé sur le film de base (12). Le film de base, la colle (16) et la couche de décollement (14) sont transparents de façon que l'image (18) et le filet (20) soient visibles dans l'épaisseur de la bande. L'image est de préférence complexe et multicolore de façon à en rendre la reproduction difficile par un éventuel contrefacteur.
