Abstract

A laminated layered construct is provided. The construct has layered material with a rupturable paper layer cohesively bonded for tamper evident security. The cohesive layer allows for rupturing of a fragile paper layer imparting or providing evidence of tampering. A method of manufacturing laminated layered construct includes a series and combination of steps.

Claims

1. A laminate construct comprising:

a first paper layer bonded with an adhesive to an upper portion of a core layer, a second paper layer bonded with the adhesive to a lower portion of the core layer, a cohesive adhered to a lower portion of the second paper layer and wherein the second paper layer comprises a rupturable paper.

2. The laminate construct of claim 1, wherein the adhesive or cohesive is colored.

3. The laminate construct of claim 1, wherein the rupturable paper is a recycled tissue.

4. The laminate construct of claim 1, wherein the core layer is a biaxially oriented polypropylene film.

5. The laminate construct of claim 1, wherein the cohesive is pressure sensitive.

6. The laminate construct of claim 1, wherein the adhesive is water based.

7. The laminate construct of claim 1, wherein the cohesive is a cold-seal water based cohesive selected from the group consisting of rubber latex, an uncured isoprene, a styrene butadiene rubber, a neoprene and combinations thereof.

8. The laminate construct of claim 1, wherein the first paper layer is a synthetic paper or a coated film, for receiving an indicia or image thereon or therein.

9. The laminate construct of claim 1, wherein an active or passive radio frequency identification tag is included within or on the laminate construct.

10. A method of manufacturing a laminate construct, comprising the steps of:

(1) applying adhesive to an underside the of a core layer

(2) applying a second paper layer to the underside of core layer

(3) applying the adhesive to the top side of the core layer

(4) drying and curing of adhesive in steps (1), (2) and (3),

(5) applying a cohesive to the underside of the second paper layer,

(6) adhering first paper layer to the top side of the core layer.

11. The method of claim 10, wherein after step (3) a pressure sensitive adhesive is applied to the second paper layer.

12. The method of claim 10, wherein a liner is releasably adhered the pressure sensitive adhesive.

13. The method of claim 10, wherein step (4) includes a temperature of about 70°

C. to about 104°

C.

14. The method of claim 10, wherein step (4) includes a temperature of about 85°

C.

15. The method of claim 10, wherein lamination proceeds at a speed of about 160 feet per minute.

16. The method of claim 10, wherein the cohesive applied at step (5) at a dry weight in the range of about 3 pounds to about 15 pounds.

17. The method of claim 10, wherein the construct has a width in the range of about 1 cm to about 15 cm.

18. The method of claim 10, wherein the first paper layer or image receiving layer has an indicia or image applied thereto.
