Abstract

A transponder label for a metallic substrate, which is relatively thin and flexible, and a cost-advantageous roll-to-roll production method for such transponder labels. A transponder inlay having a chip and an antenna is applied to the foam material element in such a manner that a first part of the antenna is situated on the top of the foam material element and a second part of the antenna is situated on the underside of the foam material element.

Claims

1. A transponder label comprising:

a dielectric foam material element having a top and an underside; and

a transponder inlay having a chip and an antenna;

wherein the transponder inlay is applied to the foam material element in such a manner that a first part of the antenna is situated on the top of the foam material element and a second part of the antenna is situated on the underside of the foam material element.

2. The transponder label according to claim 1, wherein the antenna is a strip conductor antenna.

3. The transponder label according to claim 1, wherein the foam material element possesses a maximum thickness of 1.5 mm.

4. The transponder label according to claim 1, furthermore comprising a first film element that covers at least a partial region of the transponder inlay.

5. The transponder label according to claim 4, furthermore comprising a second film element that covers at least a partial region of the first film element.

6. The transponder label according to claim 5, wherein the first or the second film element is a film element that is adapted to be written on with a laser.

7. The transponder label according to claim 1, further comprising an adhesive coating that covers at least a partial region of the underside of the foam material element and of the second part of the antenna.

8. The transponder label according to claim 4, wherein the first film element completely covers the antenna on the underside of the foam material element, and wherein a region of the first film element that comes to lie on the underside is provided with an adhesive coating over a full area of said region.

9. The transponder label according to claim 8, further comprising an adhesive covering that covers the adhesive coating on the underside of the foam material element and the second part of the antenna.

10. The transponder label according to claim 9, wherein the adhesive covering is a film web or paper web.

11. A production method for a transponder label, comprising:

providing a dielectric foam material web having a top and an underside;

providing a transponder inlay comprising a chip and an antenna;

applying the transponder inlay to the foam material web in such a manner that a first part of the antenna is situated on the top of the foam material web;

folding the transponder inlay around the foam material web in such a manner that a second part of the antenna comes to lie on the underside of the foam material web; and

applying an adhesive to the underside of the foam material web and the second part of the antenna.

12. The production method according to claim 11, further comprising the step of applying a first film element onto at least a partial region of the transponder inlay.

13. The production method according to claim 12, further comprising the step of applying a second film element onto the top of the foam material element having the first part of the antenna.

14. The production method according to claim 13, wherein the first or the second film element is a film element that is adapted to be written on with a laser.

15. The production method according to claim 13, wherein the second film element is a transparent protective film.

16. The production method according to claim 11, further comprising the step of applying a protective film to the underside of the foam material web and the second part of the antenna.

17. The production method according to claim 11, further comprising the step of applying multiple transponder inlays to the foam material web and punching individual transponder labels out of the foam material web.

18. The production method according to claim 11, wherein the foam material web has multiple transponder inlays applied to it and folded over, and further comprising the step of winding up the foam material web.
