Void films, fiber tear adhesives, security die-cuts, cut-through indicators, rub-off areas and transfer effects irrevocably indicate the initial opening or tampering of a package or the tampering of a document.
Void films destroy themselves reliably when removed and indicate the initial opening with an individual message (e.g. VOID, OPENED).
Strongly adhesive fiber tearing adhesives ensure that a seal cannot be removed without generating a fiber tear.
Security die-cuts in the material lead to the destruction of the label if an attempt is made to detach it from the substrate, thus irrevocably indicating tampering. If the label is removed, the label breaks into many small pieces. Reuse is thus ruled out.
Scratch layers have proven themselves millions of times over in secret number mailing. A PIN code for access to confidential data, accounts or as proof of authentication thus reaches the end user reliably protected.
Transfer effects result from a unique product design that offers the highest possible tamper protection: If the protective film is removed after bonding, only the adhesive and ink remain on the substrate. When trying to lift or detach, the imprint breaks into many small pieces.
