Abstract

A laminate foil is disclosed for packaging materials such as food stuffs. The laminate foil comprises a transparent film interfacing with a second layer. At the interface of the transparent film and the second layer a printed pattern is provided comprising a luminescent taggant material. The transparent film protects the printed pattern from damage, and prevents contact of the printed pattern with human skin.

Claims (28)

1 . A laminate foil material having a first exposed side and a second exposed side, said laminate foil material comprising a transparent film at the first exposed side, said transparent film facing a second layer forming an interface, said interface being provided with a printed pattern comprising a luminescent taggant material.

2 . The laminate foil material of claim 1 wherein the second layer has a reflective surface.

3 . The laminate foil material of claim 1 or 2 wherein the second layer is coated with a white coating.

4 . (canceled)

5 . The laminate foil material of claim 1 wherein the luminescent taggant material is an inorganic luminescent taggant material.

6 . The laminate foil material of claim 5 wherein the inorganic luminescent taggant material comprises a rare earth element.

7 . The laminate foil material of claim 6 wherein the inorganic luminescent taggant material comprises Samarium.

8 - 12 . (canceled)

13 . The laminate foil material of claim 1 wherein the luminescent taggant material has an emission wavelength in the infrared part of the spectrum.

14 . The laminate foil material of claim 1 wherein the luminescent taggant material has an emission wavelength in the visible part of the spectrum.

15 - 16 . (canceled)

17 . The laminate foil material of claim 1 wherein the printed pattern further comprises a particulate opaque material.

18 . The laminate foil material of claim 17 wherein the particulate opaque material comprises TiO 2 .

19 - 22 . (canceled)

23 . The laminate foil material of claim 1 wherein the luminescent taggant material is applied to the transparent film or to the second layer by a printing technique.

24 . The laminate foil material of claim 23 wherein the luminescent taggant material is applied to the transparent film or to the second layer as a component of a printing ink.

25 . The laminate foil material of claim 24 wherein the printing ink further comprises a particulate opaque material.

26 . The laminate foil material of claim 25 wherein the particulate opaque material comprises TiO 2 .

27 . (canceled)

28 . The laminate foil material of claim 24 wherein the luminescent taggant material is in particulate form.

29 . The laminate foil material of claim 28 wherein the taggant material has a mean particle size of from 0.1 to 10 μm.

30 . (canceled)

31 . The laminate foil material of claim 25 wherein the printing ink comprises from 10 to 50 wt % of the particulate opaque material.

32 . (canceled)

33 . The laminate foil material of claim 25 wherein the weight ratio of the particulate opaque material and the luminescent taggant material is from 1:1 to 20:1.

34 - 36 . (canceled)

37 . A consumer package comprising the laminate foil of claim 1 .

38 . The consumer package of claim 37 which is a beverage portion capsule.
