A food container (10) includes a recessed film mem- brane (34a) which seals the container (10). The recessed film membrane (34a) is applied with an apparatus (12) which includes a container holder (16) and a film membrane ap- plicator (14). The film membrane applicator (14) applies the film membrane (34) to the container (10) and seals the film membrane to the container. The applicator includes a sealing head (18) which places the film membrane (34) into the container (10). The sealing head (18) seals an edge (82) of the film membrane (34) to an inner wall (80) of the con- tainer (10) using heat. The film membrane (34) is moved through the applicator (14) and cut. The sealing head (18) includes two lips (84/86) to provide a double seal between the film membrane (34a) and the inner wall (80) of the con- tainer (10).
