A radio frequency identification (RFID) tag and method of manufacturing the same. In a preferred embodiment, the RFID tag includes a radio frequency (RF) inlay, the RF inlay including a carrier sheet, an antenna printed on the carrier sheet and a wireless communication device bonded to the antenna. The RFID tag also includes a plastic extrudate, the RF inlay being disposed within the extrudate so that the antenna and the wireless communication device are encapsulated on all sides within the extrudate. Optional metallic reflector and mounting adhesive layers may be laminated onto the underside of the extrudate. The present invention is also directed to an automated method for manufacturing the above RFID tag, such a method involving, in one embodiment, feeding a continuous supply of RF inlays into a cross-head extruder to yield a continuously extruded block and then cutting the block between successive antennae to yield a plurality of individual RFID tags.

An EAS marker includes a rigid bottom piece of molded plastic having the shape of an open rectangular box. An elongated resonator is disposed in the bottom piece, the resonator being bowed downwardly about its longitudinal axis. A rigid separator of molded plastic is positioned over the open top of the bottom piece, thereby loosely encasing the resonator in the bottom piece. The method of making the EAS marker is preferably automated, with the top piece, the bottom piece and the separator being manufactured by rotary extrusion molding as part of a continuous web. The various continuous webs are automatically laminated to one another at nips between pairs of rollers.

An EAS marker and method of manufacturing same. In a preferred embodiment, the EAS marker comprises a rigid bottom piece of molded plastic having the shape of an open rectangular box. An elongated resonator is disposed in the bottom piece, the resonator being bowed downwardly about its longitudinal axis. A rigid separator of molded plastic is positioned over the open top of the bottom piece, thereby loosely encasing the resonator in the bottom piece. The foregoing bottom piece, resonator and separator are all positioned within the cavity of a rigid top piece of molded plastic having the shape of an inverted open rectangular box, the separator being press-fit against the interior surface of the top wall of the top piece, the bottom piece being press-fit against the interior surfaces of the side walls and end walls of the top piece. The top wall of the top piece is provided with a recessed area in which a biasing element is disposed, the biasing element being retained in the recessed area by the separator. The separator is shaped to include a projection that extends downwardly beyond the remainder of the bottom surface of the separator, the projection being sized and shaped to contact the top of the resonator only within a circular area approximately 0.1 inch in diameter located in approximately the middle of the resonator. The present invention is also directed to an automated method and apparatus for manufacturing the above EAS marker. In a preferred embodiment, each of the top piece, the bottom piece and the separator is manufactured, by rotary extrusion molding, as part of a continuous web, and the various continuous webs are automatically laminated to one another at nips between pairs of rollers.

This invention relates to a thermal transfer laminate, comprising: a facestock comprising a first layer having an upper surface and a lower surface, and a heat-activatable adhesive layer underlying the lower surface of said first layer; an adhesion-promoting layer overlying the upper surface of said first layer; an abrasion-resistant transparent coating layer overlying said adhesion-promoting layer; and another adhesive layer overlying said abrasion-resistant coating layer. In one embodiment, an ink or graphics layer overlies the upper surface of the first layer of the facestock and provides a pictorial design and/or print message. In one embodiment, the laminate is adhered to a carrier sheet. In one embodiment, the laminate is adhered to a substrate such as an automotive interior surface.

Method of manufacturing an EAS marker

The present invention is a tamper proof label comprised of a thicker support portion and a thinner fragile portion. The label is formed of a plurality of layers of varnish, adhesive, plastic, and ink. The label incorporates an authentication region in which the text can be readily deciphered only with a special viewer. The top surface of the label can be written on with ink and is difficult to erase without destroying the fragile portion of the label. The label is adhered to a product by an adhesive which becomes aggressively bonded to the product over a relatively short period of time. In addition, the adhesive leaves a residue which is visible when illuminated with ultraviolet light.
