Abstract
A method of making a molded article having a curved surface, such as plates or serving trays, and the resulting molded articles. The in-mold label (IML) is a laminated film that includes a backing layer, a printed surface incorporating one or more designs thereon, a protective film layer, and one or more notches each having adjacent edges separated by a gap of predetermined distance and configured to intersect to ensure conformance of the IML to the angled or curved peripheral portion of the article. The article has front and back sides and a central portion bounded by a peripheral portion having a perimeter that is raised on the front side of the article wherein the peripheral portion transitions from the perimeter to the central portion by an angled surface, a curved surface or combinations thereof, with the article including the IML at least peripheral portion of the molded article.
