Abstract
A foam thermoplastic container e.g. cup, bowl molded from expandable thermoplastic particles e.g. expandable polystyrene, has a film made of a thermoplastic resin e.g. solid polystyrene, rubber-modified polystyrene, PET, polyethylene, polypropylene, fused to its inner sidewall surface by heat and pressure to create a barrier to resist the leakage of liquid and food with oil and/or fatty components and to increase the rim strength of the container. The thermoplastic resin film can be fused to the outer surface of the container for printing purposes and/or to create a barrier and/or can be fused to the base surfaces of the container. The molding machine used to form the foam container is used to fuse the film to the container.
