Abstract

Claims (24)

1. A thermoplastic polymeric film comprising at least one thermoplastic polymer, wherein:

a. at least one portion of said film is micro-embossed with a micro-embossing pattern;

b. at least one portion of the film is embossed with a first embossing pattern having a first embossing depth which is greater than the micro-embossing depth; and,

c. wherein the film has a basis weight of about 18 gsm or less and an impact strength of about 15 g to 40 g,

wherein the micro-embossing pattern of the design comprises lines having a density of at least about 75 lines/inch.

2. The film of claim 1 , wherein the micro-embossed portion of the film has a ratio of Gf/Gi of less than about 0.7 or a specular gloss of less than about 35 gloss units.

3. The film of claim 1 , wherein the micro-embossing pattern has a micro-embossing depth of about 80 μm or less.

4. The film of claim 1 , wherein the embossed portion of the film has a ratio of Gf/Gi that is greater than about 0.7 or a specular gloss of greater than about 35 gloss units.

5. The film of claim 1 , wherein the embossed portion of the film has a ratio of Gf/Gi of less than about 0.7 or a specular gloss of less than about 35 gloss units.

6. The film of claim 1 , wherein the film comprises at least one colorant.

7. The film of claim 6 , wherein the colorant is printed onto at least one side of the film.

8. The film of claim 7 , wherein at least one colorant forms a printed design.

9. The film of claim 8 , wherein the printed design is in register with the embossed pattern.

10. The film of claim 6 , wherein the colorant is dispersed throughout the film.

11. The film of claim 1 , wherein the thermoplastic polymer comprises a polyolefinic polymer, a polyolefinic copolymer, an olefinic block copolymer, or combinations thereof.

12. The polymeric film of claim 1 , wherein at least one portion of the film is embossed with a second embossing pattern having a second embossing depth which is greater than the first embossing depth.

13. The polymeric film of claim 1 , wherein the film is laminated to a substrate.

14. A thermoplastic polymeric film comprising at least one thermoplastic polymer, wherein:

a. at least one portion of said film is micro-embossed with a micro-embossing pattern having a micro-embossing depth and a line density of at least about 125 lines/inch;

b. at least one portion of the film is embossed with a first embossing pattern having a first embossing depth which is greater than the micro-embossing depth; and,

c. at least one portion of the film is embossed with a second embossing pattern having a second embossing depth which is greater than the first embossing depth;

d. the micro-embossed portion of the film has a ratio of Gf/Gi of less than about 0.7 or a specular gloss of less than about 35 gloss units;

e. the portion of the film embossed with the second embossing pattern has a ratio of Gf/Gi that is greater than about 0.7 or a specular gloss of greater than about 35 gloss units; and,

f. the film has a basis weight of about 18 gsm or less and an impact strength of about 15 g to 40 g.
