Methods for making coated films

1. A method of coating a film comprising:

suspending in water a coating composition comprising particulate filler, binder composition comprising acrylic polymer and ethylene acrylic acid copolymers, wherein the ethylene acrylic acid copolymers include ethylene acrylic acid copolymer, ethylene methacrylic acid copolymer, and C 1-6 esters of each, or combinations thereof; non-cross-linking adhesion promoter, and optionally urethane polymer, styrene-acrylic copolymer, or a combination thereof, and wherein cross-linker(s) are substantially absent from the coating composition;

applying a layer of the suspended coating composition onto the film;

removing the water from an adhered layer of the coating composition; and

forming the film having a dry weight of the coating composition within a range of from 0.50 g/m 2 to 6.0 g/m 2 and a 45° Gloss (ASTM D2457) of less than 30.

2. The method of claim 1 , wherein the application step comprises applying a layer of the suspended coating composition onto a primer layer adhered to the film, the primer layer comprising an iminated acrylic polymer, a polyethyleneimine, an epoxy, a polyurethane, or a mixture thereof.

3. The method of claim 1 , wherein the film is an oriented film having at least one layer comprising polypropylene.

4. The method of claim 1 , wherein an average particle size of the particulate filler is less than 10 μm.

5. The method of claim 1 , wherein the particulate filler is present in the coating composition, on a dry weight basis, within a range from 30 wt % to 75 wt %, based on a total weight of the coating composition.

6. The method of claim 1 , wherein organic solvents are substantially absent.

7. The method of claim 1 , wherein the acrylic polymer is present in the coating composition, on a dry weight basis, within a range from 5 wt % to 35 wt %, based on a total weight of the coating composition.

8. The method of claim 1 , wherein the urethane polymer or the styrene-acrylic copolymer, or combination thereof, is present in the coating composition, on a dry weight basis, within a range from 5 wt % to 25 wt %, based on a total weight of the coating composition.

9. The method of claim 1 , wherein when the urethane polymer or the styrene-acrylic copolymer, or combination thereof is present, and the particulate filler is present in the coating composition, on a dry weight basis, within a range from 30 wt % to 55 wt %, based on a total weight of the coating composition.

10. The method of claim 1 , wherein the film is formed into a label by application of an adhesive to at least part of the film.

11. The method of claim 10 , wherein the label is printed upon by a thermal transfer ribbon printer.

12. The method of claim 1 , wherein the ethylene acrylic acid copolymer component is an ionomer comprising from 65 wt % to 95 wt % of ethylene derived units and from 5 wt % to 35 wt % acrylic or methacrylic acid, C 1-6 esters of each, or combinations thereof, and a metal ion or ammonia associated therewith.

13. The method of claim 1 , wherein the coating composition comprises, on a dry weight basis, within a range from 0.5 wt % to 10 wt % of the non-crosslinking adhesion promoter, based on a total weight of the coating composition.

14. The method of claim 1 , wherein the non-cross-linking adhesion promoter is selected from a group consisting of ethylenically unsaturated acrylates and C 1-6 esters thereof, aceto-acetoxy-ethylmethacrylate and C 1-6 esters derivatives thereof, maleic anhydride grafted polymers, and mixtures thereof.

15. The method of claim 1 , wherein organic solvents are substantially absent from the suspending.

16. The method of claim 1 , wherein the film having the coating composition comprises receptability to printing, UV-curing inks, thermal-curing inks, or otherwise, thereon.

17. The method of claim 1 , further comprising forming aqueous mixtures or emulsions of each component in the coating composition prior to the suspending.

18. The method of claim 1 , wherein the removing comprises evaporating, heating, decreasing pressure, air-drying, exposing to ultraviolet or other radiative sources, exposing convective sources, or combinations thereof.

19. The method of claim 1 , further comprising re-coating at least one side of the film coated with the coating.

20. The method of claim 1 , further comprising treating at least one side of the film.
