Claims18
A method for providing a packaging material, comprising:
- feeding a web of packaging material through a packaging material processing unit;
- determining a target position of said packaging material;
- and controlling a printing unit to print an RFID antenna at said target position, wherein the material used for printing the RFID antenna is a conductive substance, wherein controlling a printing unit to print an RFID antenna at said target position further comprises printing one or more resonance circuits adjacent to said antenna;
- and coating individual resonance circuits with a substance, the substance configured to change the resonance frequency of the resonance circuit.
A packaging material comprising a plurality of layers together forming a laminate configured to store liquid food content when the packaging material is formed into a package container, wherein said packaging material comprises at least one RFID antenna being printed when a web of said packaging material is fed through a packaging material processing unit, and wherein said packaging material comprises one or more resonance circuits positioned adjacent to said RFID antenna, wherein individual resonance circuits are coated with a substance, the substance configured to change the resonance frequency of the resonance circuit.
