A composite structure includes a polystyrene foam substrate bonded on at least one major surface to an oriented polypropylene film employing an acrylic adhesive composition. In addition to its other advantageous characteristics, the bond strength between the polystyrene foam and the oriented polypropylene film components of the composite structure is unusually high. The composite can be readily thermoformed into a variety of useful articles such as disposable cups, plates, cartons, containers, and the like.
