  • METHOD OF MANUFACTURING LAMINATED MATERIAL FOR SECURITY TAG
    Publication number: 20080248266
    Abstract: A laminated material suitable for fabricating miniaturized security tags which have the uniform resonance frequency, and security tags obtained by using the laminated material, are provided. A manufacturing method of a laminated material for security tags characterized in that metal foils are laminated on both sides of a previously formed synthetic resin film, and security tags obtained by using the laminated material by the manufacturing method, are provided. Because the lamination is performed on the previously formed resin film, the amount of variation in thickness of the resin film is small, and the thin resin film can be precisely manufactured. Further, because the oriented film has a relatively high strength even for a thin film, the laminated material is easy to be etched for forming a circuit. The security tag obtained by using a previously formed resin film can satisfy both uniformizing the resonance frequency and miniaturizing the security tag simultaneously, and has an excellent performance.
