1. A recyclable polyethylene-based packaging film, comprising:
a coextruded web comprising:
a skin layer comprising an optically transparent polyethylene polymer;
a heat sealant layer forming an innermost layer of the packaging film, the heat sealant layer comprising a polyethylene polymer;
a moisture barrier layer disposed intermediate the skin layer and the heat sealant layer; and
an energy-cured coating disposed on the skin layer of the coextruded web and forming an outermost surface of the packaging film, wherein the energy-cured coating has a coating weight which is effective to impart a property in the packaging film selected from reduced susceptibility to melting, reduced susceptibility to deforming, or both, and
wherein a melting temperature of the outermost surface of the packaging film is at least 100 degrees Celsius higher than a melting temperature of the innermost layer of the packaging film.

14. A recyclable polyethylene-based packaging film, comprising:
a coextruded web comprising:
a skin layer comprising an optically transparent polyethylene polymer;
a heat sealant layer forming an innermost layer of the packaging film, the heat sealant layer comprising a polyethylene polyolefin polymer;
a gas barrier layer disposed intermediate the skin layer and the heat sealant layer;
a first moisture barrier layer interposed between the skin layer and the gas barrier layer; and
a second moisture barrier layer interposed between the gas barrier layer and the heat sealant layer; and
an energy-cured coating disposed on the skin layer of the coextruded web and forming an outermost surface of the packaging film, wherein the energy-cured coating has a coating weight which is effective to impart a property in the packaging film selected from reduced susceptibility to melting, reduced susceptibility to deforming, or both; and
wherein a melting temperature of the outermost surface of the packaging film is at least 100 degrees Celsius higher than a melting temperature of the innermost layer of the packaging film.
