Abstract

Abstract A composite laser-etchable tamper-proof label which may be adhered to a surface and re-used at least once before being finally adhered to a surface in a tamper-proof manner. The label has an upper layer of a brittle laser-etchable acrylic composite material which is bounded on its underside, by means of an acrylic adhesive, to a silicone-release coated polyester film. This film is coated on its underside with a coating of a pressure-sensitive acrylic adhesive, which has a controlled level of clean removability so that it can easily be detached from a surface to which it is bonded. Also, the upper layer can be released, without damage, from the silicone coated polyester film
