Abstract: A low-cost, throw-away receptacle such as a cup, picnic plate, or container, and closures for such receptacles, are made from foamed plastic material, preferably foamed polystyrene, which is lined on one or both sides with unoriented polyolefin film, preferably polypropylene. The film is secured to the foamed plastic base material using as a heat-sensitive adhesive a vinylic polymer or polyamide resin. Preferred vinylic polymers are based on vinyl acetate, and include polyvinyl acetate maleate copolymer. The film is coated with the initially wet adhesive which is dispersed in an emulsion or solvent carrier, and dried before laminating the film to the foam material. Laminating is done by heating the foam material to a temperature of from 250.degree.-275.degree. F., preheating the coated film to from 100.degree.-180.degree. F., and pressing the coated film surface against the heated foam using a cold platen or roller for from 10 to 15 seconds.
