Abstract
A coated film having improved optical properties and increased recyclability properties comprising a combination of: (a) at least one film layer of a recyclable polyolefin; and (b) at least one recyclable coating layer disposed on at least a portion of the surface of one side of the at least one film layer of the recyclable polyolefin such that the at least one coating layer provides the coated film with an increase gloss at 60°, a reduced haze, an increase in clarity; and a recyclability property.

A packaging article comprising:
- a coated film comprising
- (a) at least one film layer of a recyclable polyolefin;
- and
- (b) at least one coating layer;
- wherein the coated film has a gloss at 60° of at least 85 units;
- wherein the coated film has a haze of 30 percent lower than a non-coated film;
- wherein the at least one coating layer has a recyclability property of less than a 50 percent change in performance compared to a film without the coating layer;
- and
- wherein the at least one coating layer is disposed on at least a portion of the surface of one side of the at least one film layer of the recyclable polyolefin.
A process for producing a coated film having improved optical properties and recyclability properties comprising contacting together:
- (a) at least one film layer of a recyclable polyolefin;
- and
- (b) at least one coating layer;
- wherein the at least one coating layer has a gloss at 60° of at least 85 units;
- wherein the coated film has a haze of 30 percent lower than a non-coated film;
- wherein the at least one coating layer has a recyclability property of less than a 50 percent change in performance compared to a film without the coating layer;
- and wherein the at least one coating layer is disposed on at least a portion of the surface of one side of the at least one film layer of the recyclable polyolefin.
A waterborne coating composition comprising:
- (A) at least one polymeric dispersant;
- (B) at least one neutralizing agent compound having a boiling point of less than 140° C.;
- (C) optionally, at least one polyolefin base resin having a melt index of greater than 1;
- and
- (D) optionally, at least one wax compound.
