Abstract
A reinforcing tape is illustrated with a length of elongate, adhesive-coated reinforcing tape configured to reinforce a packaging substrate. The reinforcing tape may include a first major surface and a second major surface opposing the first major surface. The reinforcing tape may also include a plurality of RFID devices attached to the first major surface of the reinforcing tape in longitudinally spaced apart relation along the length of the reinforcing tape.
Claims20
A reinforcing tape, comprising:
- a length of elongate, hot melt adhesive-coated reinforcing tape configured to reinforce a packaging container substrate, the reinforcing tape comprising a first major surface and a second major surface opposing the first major surface, wherein the reinforcing tape has a longitudinal tensile strength of at least about 8.2 kgf;
- a plurality of RFID devices attached to the first major surface of the reinforcing tape in longitudinally spaced apart relation along the length of the reinforcing tape, wherein each RFID device comprises an antenna;
- and,
- a conductive element spanning at least a portion of the length of the reinforcing tape between adjacent RFID devices for enhancing the reading and transmitting properties of one or more of the RFID devices.
1 more element
An adhesive tape, comprising:
- at least one RFID device that includes an integrated circuit chip configured for use in RFID and an antenna electrically coupled thereto;
- and
- at least one conductive element attached to or embedded in the tape and extending a predetermined distance beyond the chip and antenna, wherein the conductive element comprises at least one of (i) a conductive filament or (ii) a conductive hot melt adhesive that includes a plurality of conductive particles, and wherein the conductive element is configured for enhancing reading and transmitting properties of the RFID device.
