    Abstract: A system and method that causes at least one item to be placed within a portion of an elastic film positioned across a top surface of a container, the portion including a center portion in which the at least one item is placed. Air may be extracted from the container to create a vacuum within the cavity and to expand the center portion to create a void in the center portion within the cavity. Air may flow into the container to release the vacuum and contract the center portion of the elastic film as the void is decreased and eliminated.

    Abstract: A film tensioning and steering system can be configured to extract a film from a film source. One or more film characteristics can require that the film tensioning and steering system be isolated from the film source so that a film tension can be maintained within the film tensioning and steering system. A first drive roller pair and a second drive roller pair can be configured to secure the film and enable a dampening roller to maintain the film tension between the first drive roller pair and the second drive roller pair. Additionally, the dampening roller can store an amount of the film as a film buffer. Accordingly, the film tensioning and steering system can maintain the film tension such that a steering system can align the film before the first drive roller pair provides the film at a proper alignment to a downstream system.
