Abstract

A multilayer article including a film layer having a textured first surface and an opposite second surface, wherein the film layer is printable, and a nonwoven material layer bonded to the second surface of the film layer. The film layer may include a semi-crystalline polylactic acid and may be receptive to inkjet printing.

First claim

What is claimed is:

1. A multilayer article comprising:
a film layer comprising a textured first surface and an opposite second surface, wherein the film layer is printable; and
a nonwoven material layer bonded to the second surface of the film layer.

2. The multilayer article of claim 1 , wherein the film layer comprises a semi- crystalline polylactic acid.

3. The multilayer article of claim 2 , wherein the film layer is receptive to inkjet printing.

4. The multilayer article of claim 3 , wherein the inkjet printing comprises at least one of solvent inkjet printing, latex inkjet printing, UV inkjet printing, and screen printing.

5. The multilayer article of claim 1 , wherein the film layer further comprises at least one of an amorphous polylactic acid, a plasticizer, and a nucleating agent.

6. The multilayer article of claim 1 , wherein the film layer further comprises a second polymer having a Tg of at least 25° C.

7. The multilayer article of claim 1 , wherein the nonwoven material layer comprises a polylactic acid.

8. The multilayer article of claim 1 , wherein the film layer is thermally bonded to the nonwoven material layer.

9. The multilayer article of claim 1 , wherein at least one of the film layer and the nonwoven material layer comprises at least one of particles for surface matting, flame retardant materials, hydrolysis-inhibiting additives, and antimicrobials.

10. The multilayer article of claim 1 , wherein the nonwoven material layer comprises an outer surface, and wherein the article further comprises a pressure sensitive adhesive layer bonded to the outer surface of the nonwoven material layer.

11. The multilayer article of claim 1 , wherein the second surface of the film layer comprises at least one of a textured surface and a contoured surface, and wherein the nonwoven material layer comprises a top surface that is at least one of textured and contoured to mate with the textured second surface of the film layer.

12. The multilayer article of claim 11 , wherein the nonwoven material further comprises at least one of a textured outer surface and a contoured outer surface opposite the top surface.

13. The multilayer article of claim 11 , wherein the first surface of the film layer comprises a surface pattern that is different from at least one of:
a surface pattern of the second surface of the film layer; and
a surface pattern of the top surface of the nonwoven material layer.

14. The multilayer article of claim 1 , wherein at least one of the film layer and the nonwoven material layer comprise multiple sublayers.

15. A method of making a multilayer article comprising the steps of:
bonding a film layer to a nonwoven material layer, wherein the film layer comprises a first surface and an opposite second surface, and wherein at least one of the film layer and the nonwoven material layer comprises a polylactic acid;
texturing a first surface of the film layer; and
imaging the film layer.
