发明名称 METHOD FOR CREATING CAVITIES IN SECURITY DOCUMENTS, IN PARTICULAR CHIP CARDS
摘要 The method involves introducing a separating layer on a point between plastic layers, where the separating layer reaches not onto an edge of a document e.g. security document. The plastic layers and the separating layer are laminated with each other, and a desired cavity is produced above the separating layer by stamping, where the plastic layer is made of polycarbonate, polyethylene terephthalate or polyethylene terephthalate derivatives. The separating layer is made of aluminium, silicon, Teflon or polyamide foil and containing the silicon containing ink.
