A food container includes a recessed film membrane which seals the container. The recessed film membrane is applied with an apparatus which includes a container holder and a film membrane applicator. The film membrane applicator applies the film membrane to the container and seals the film membrane to the container. The applicator includes a sealing head which places the film membrane into the container. The sealing head seals an edge of the film membrane to an inner wall of the container using heat. The film membrane is moved through the applicator and cut. The sealing head includes two lips to provide a double seal between the film membrane and the inner wall of the container.
