RADIO FREQUENCY IDENTIFICATION TAGS AND LABELS |
摘要 |
Radio frequency identification elements (15), including linerless or lined labels (56), are produced with enhanced effectiveness. The antenna (18) is printed with conductive ink or toner, and cross-over may be provided by spot printing a non-conductive material (21) over a portion of the antenna and th en printing a conductive cross-over element (25) on the non-conductive material (21). Typically the antenna (18) is printed on one face (22) of a web (10), and the radio frequency identification chip (30) is moved into contact with the opposite face (27) of the web (10) so that the contacts (31) penetrate t he web and engage the antenna so that the web material acts as a dielectric. Alternatively part of the antenna on the first face may be over-printed with a non-conductive material (40) and the chip attached to the first face passing through openings (41) in, or penetrating, the non-conductive material (40) t o engage the antenna. A protective substrate (45, 46) or coating is provided o n at least one of the chip and antenna, for example by heating heat expandable microspheres, or applying a substrate having hot melt adhesive. The antenna may be printed with a printing media comprising a carrier including resin an d wax and containing conductive material in it, and by heating the carrier so that it becomes fluid and is applied as a thick film on the substrate, and b y allowing the carrier to cool so as to provide a conductive antenna. The printing may be accomplished at a speed of about 500 feet per minute or more . |
