Abstract
A molded article comprising a food container top, and a method for producing same, is disclosed. The method includes providing a mold for forming the molded article, wherein the mold defines a frame, a utensil located substantially coplanar with the frame and a frangible link between the frame and the utensil, providing an in-mold lidding film having a heat activatable lower surface, positioning the in-mold lidding film adjacent to an interior molding surface of the mold, molding the molded article from a heated thermoplastic resin contained within the mold, whereby the heated thermoplastic resin contacts a perimeter of the heat-activatable lower surface of the in-mold lidding film, and the perimeter of the heat-activatable lower surface of the in-mold lidding film is molded to the frame of the article such that the in-mold lidding film hermetically seals an opening defined by the frame.
