Abstract

The invention consists in an RFID label consisting of at least: one functional layer comprising at least one electronic component, one antenna connected to the electronic component; one upper layer; one lower layer having an adhesive surface; wherein the upper and lower layers consist of one or more materials capable of resisting to ultraviolet radiation and/or of filtering the ultraviolet radiation. The invention also includes the method for manufacturing the RFID label and the machine applying the method for manufacturing the RFID label.

Claims

1. An RFID label comprising at least:

one functional layer comprising at least;

one electronic component; and

one antenna connected to the electronic component;

one upper layer; and

one lower layer having two adhesive surfaces;

wherein the upper and lower layers consist of one or more materials capable of resisting ultraviolet radiation and/or of filtering ultraviolet radiation, and

wherein a supplementary protection layer against ultraviolet radiation is printed on a top face of the lower layer and configured to protect the electronic component and the antenna against ultraviolet radiation, the top face being adhesively joined to the functional layer.

2. The RFID label according to claim 1, wherein the upper layer is in paper.

3. The RFID label according to claim 1, wherein the upper layer is in a synthetic material having a printable coating.

4. The RFID label according to claim 1, wherein

the lower layer is in paper capable of resisting ultraviolet radiation and/or of filtering the ultraviolet radiation, and

a bottom face of the lower layer has a pressure sensitive face protected by a detachable layer.

5. The RFID label according to claim 4, wherein the pressure sensitive face consists of an adhesive, the physico-chemical properties of which do not deteriorate if the adhesive is subject to ultraviolet radiation.

6. The RFID label according to claim 4, wherein the detachable layer is in paper.

7. The RFID label according to claim 4, wherein the detachable layer is in synthetic material.

8. The RFID label according to claim 4, wherein the detachable layer is siliconized.

9. The RFID label according to claim 1, wherein the lower layer is in synthetic material capable of resisting ultraviolet radiation and/or of filtering the ultraviolet radiation and having a pressure sensitive face protected by a detachable layer.

10. The RFID label according to claim 1, wherein the functional layer is in paper on which is etched or printed the antenna connected to the electronic component.

11. The RFID label according to claim 1, wherein the functional layer is in flexible synthetic material on which is etched or printed the antenna connected to the electronic component.

12. The RFID label according to claim 1, wherein the layers are assembled together by adhesive bonding.

13. The RFID label according to claim 1, wherein at least one of the upper layer, the lower layer, or the functional layer has a combination of inks capable of resisting to ultraviolet radiations and/or of filtering ultraviolet radiation.

14. The RFID label according to claim 1, wherein at least one of the upper layer, the lower layer, or the functional layer have one or more layers for printing a combination of inks capable of resisting to ultraviolet radiations and/or of filtering ultraviolet radiation.

15. The RFID label according to claim 1, wherein the supplementary protection layer is at least one ink layer.

16. The RFID label according to claim 1, wherein the supplementary protection layer is directly printed on the top face opposite a bottom face of the lower layer.

17. The RFID label according to claim 16, further comprising a detachable layer detachable to the bottom face of the lower layer, wherein the lower layer with the printed supplementary protection layer is bonded between the functional layer and the detachable layer.

18. The RFID label according to claim 1, wherein the supplementary protection layer is formed of a black flexographic layer, a white screen printing layer, and a screen printing layer.
