Abstract
The present invention relates to an RFID device that is intended to be used in connection with direct or indirect packaging of consumer food products, such as with the use of food trays, totes and other transport packaging for perishable items. The RFID device may include a RFID inlay assembly that has been encased in a laminate that is safe for use with food products.
Claims23
An RFID device for use in direct or indirect food packaging applications, comprising;
- an RFID inlay having a chip encoded with product information and an antenna bonded to said chip;
- first and second substrates, each of said substrates having first and second surfaces, and first and second transversely extending edges and first and second longitudinally extending sides and each of said substrates being GRAS;
- and
- wherein said RFID inlay is disposed between each of said first and second substrates and each of said first and second longitudinally extending sides and each of said first and second transversely extending edges are sealed to one another so as to create a sealed enclosure for said RFID inlay.
A consumer food tray for transporting consumer food goods, comprising:
- a tray having a base with first and second sides, said base having end walls encircling said base and extending generally upwardly from said base;
- a consumer food good;
- an RFID device, said RFID device comprising an RFID inlay, said inlay having a chip encoded with product information and an antenna bonded to said chip, said RFID device including first and second GRAS substrates each of said first and second substrates having first and second surfaces, said inlay is disposed between said first surface of said first substrate and said second surface of said second substrate;
- and
- wherein said RFID device is contact with said consumer food good.
A GRAS RFID device, comprising:
- a first laminated structure having a integrated circuit encoded with product information relating to a consumer good, said integrated circuit connected to an antenna, said antenna and said integrated circuit disposed between first and second substrates to create a first laminate assembly;
- a second structure having first and second GRAS films with each of said first and second GRAS films having first and second end edges and first and second side edges;
- and
- wherein said first laminated assembly is disposed between said first and second GRAS films to create a second laminated assembly.
A method for producing a GRAS RFID device in connection with a food carrier, comprising the steps of:
- providing an RFID inlay manufactured using a strap, the inlay having an antenna;
- placing said RFID inlay on a first GRAS substrate;
- covering said RFID inlay and said first GRAS substrate with a second GRAS substrate;
- adhering said first and second GRAS substrates together with said RFID inlay contained there between to form a laminated assembly;
- and
- affixing said laminated assembly to a food carrier.
