  • Multilayer Security Seal
    Publication number: 20090091457
    Abstract: The present invention relates to a multilayer security seal comprising a carrier and an adhesive layer arranged on the entire area underneath the carrier, the following layers being arranged between carrier and adhesive layer in any case: a) a first layer—marking layer—not applied to the entire area, b) a second layer—contrast layer—applied to the entire area. It is proposed that an individual identifier, which is at least partly provided in the composite, be contained for the purpose of verification.
