ABSTRACT:
An apparatus for enveloping successive groups of items in a plastic film as the items traverse a linear path. Items are gathered in a group, and the group of items is then inserted in a tubular packaging film as the items and the film are conveyed at the same linear velocity. After the items are completely enveloped in the film, the film is severed and sealed to fully encapsulate them in the film. A vacuum is used to eliminate excess air generated within the tube, and also, in one form of the invention, form side gussets as sealing dies are closed. A tight package made at speeds results, with no need for any holes in the film to relieve internal air pressure.
