An easy tear packaging film, a method of producing the film and a grocery bag formed from the film are described. The film is formed from a coextruded mono-web having a linear low density polyethylene heat sealant layer, a high density polyethylene barrier layer and a polypropylene print layer. The mono-web is uniaxially oriented in the transverse direction to provide linear tear characteristics. Ink is printed on the print layer. A clear energy cured coating is disposed on the print layer over the ink to provide high gloss, scuff resistance and heat resistance. The film exhibits the linear tear characteristics of the mono-web because the energy cured coating has a negligible affect on the tear properties of the film.
