A coating for a polyolefin film is made from an acrylic polymer or ionomer resin and an ink receptive particulate such as a molecular sieve and/or a carbohydrate polymer such as cellulose, carboxymethyl cellulose or corn starch. The coating composition facilitates adhesion of ink to the polyolefin film.
