ABSTRACT:
A tamper resistant label having a film to which non-adherent and visible indicia are applied. The film, with the non-adherent visible indicia is thereafter corona treated, and a layer of the same material or a material with the same index of refraction as the non-adherent visible indicia is applied, overlying the film. In this arrangement, any removal of the film does not affect the visible indicia, but the region in the vicinity of the visible indicia is destroyed. The non-adherent visible indicia may take the form of any predetermined pattern such as the term void to indicate to a viewer that the overlying protective film has been removed.
