Title
(EN) TAMPER INDICATING ADHESIVE DEVICE
(FR) DISPOSITIF ADHESIF INDICATEUR D'EFFRACTION
Abstract
(EN)
A tamper indicating device includes a light transmissive backing an a layer of adhesive. The backing comprises a blown film including a first, continuous phase and a second, discontinuous phase. The backing is normally light transmissive, and becomes opaque upon tampering sufficient to internally delaminate said backing. Preferably, the blown film contains from 60 to 85 parts by weight of the first, continuous phase and from 15 to 40 parts by weight of the second, discontinuous phase. More preferably, the first phase comprises polypropylene and the second phase comprises an ethylene/vinyl acetate copolymer or ethylene/vinyl alcohol copolymer or an ethylene/vinyl acetate/vinyl alcohol terpolymer. The tamper indicating device can include either or both of an initially viewable indicia that becomes obscured upon internal delamination of the backing and a latent indicia that becomes viewable upon internal delamination of the backing.

Cette invention se rapporte à un dispositif indicateur d'effraction qui comprend une couche dorsale transparente et une couche d'adhésif. La couche dorsale se compose d'un film soufflé contenant une première phase continue et une seconde phase, discontinue. La couche dorsale est transparente en situation normale et devient opaque lors d'une effraction suffisante pour produire la délamination interne de la couche dorsale. Le film soufflé contient de préférence 60 à 85 parties en poids de la première phase continue et 15 à 40 parties en poids de la seconde phase discontinue. La première phase comprend de préférence du polypropylène et la seconde phase comprend un copolymère éthylène/acétate de vinyle ou un copolymère éthylène/alcool de vinyle ou un terpolymère éthylène/acétate de vinyle/alcool de vinyle. Ce dispositif indicateur d'effraction peut comporter une marque initialement visible, qui s'obscurcit après délamination interne de la couche dorsale, et/ou une marque latente qui devient visible après délamination interne de la couche dorsale.
