Abstract
A packaging method and apparatus are disclosed in which a substantially horizontal bed is loaded with a series of independent magazines. Each of the magazines supports a plurality of open trays which are loaded with the desired contents. The magazines are moved along the bed to a vacuum chamber where a cover film is applied and the magazines are independently supported. The vacuum chamber is then closed to allow for evacuation and sealing of the covered trays and the magazines supporting the finished packages are removed from the vacuum chamber.
