Abstract
An apparatus may include a film support roller supporting a film roll and a housing that may include a sealing portion having an aperture sized to receive a top portion of a container. The housing may define a film path leading from the film roll to the sealing portion. A guide support assembly may have a ramp and at least one guide truss positioned along the film path. The ramp and the guide truss may guide the film across the aperture within the sealing portion, covering the aperture. The motor may advance the film along the film path. The heating element may emanate energy. The controller may cause the motor to advance the film onto the ramp and cause the heating element to emanate energy to cause the film to seal the top portion of the container.
