Clearly visible tamper evidence.

Individually designed seals with void effects are used wherever tampering with a self-adhesive solution has to be clearly and irrevocably indicated.

Upon first detachment, a clearly visible message irreversibly appears within an initially uniformly colored surface, thus unambiguously indicating any kind of opening attempt. Even if the seal is precisely resealed the warning message triggered by the first opening remains unchanged.

Schreiner ProSecure possesses long-standing development and production expertise and the capabilities to create customized void effects for any application and design requirement. Examples include lettering/inscriptions, logos and graphics elements.

Void effects can be individually designed, for instance with texts (“void”), logos and graphic elements.
