Abstract
A container has a product in a product-receiving area and has a sealing area surrounding the product-receiving area. A length of film is arranged over the container. A space above the film is evacuated using an evacuating portion of an upper sealing module arranged over the film, so as to cause a portion of the film to conform to the upper sealing module. An area of the film is cut out by moving a cutting tool relative to the upper sealing module from a recessed position to a cutting position. The cut-out area of film includes the portion of the film conformed to the upper sealing module, is brought into contact with the sealing area of the container by moving the upper sealing module relative to the container, and is sealed to the sealing area of the container using a heat sealing portion of the upper sealing module.
