A B S T R A C T THERMOPLASTIC CONTAINER A process is disclosed for the fabrication of a thermoplastic container having a lid bonded thereto. The container and lid are formed from laminated thermo- plastics wherein at least one of the layers that forms the laminate is dielectrically heatable. The heatable layers of the cup and lid are placed in contact with one another, dielectrically heated, and melt together to form a continuous bonded area or lid seam between the cup and lid. The materials of the cup and lid are selected such that the resultant bonded area forms an oxygen barrier between the contents of the container and the outside environment. The strength of the bonded area is selected such that the lid may be manually-removed from the container.
