The meat packaging machine of the present invention is designed to vacuum pack meat products between two webs of heat sealable thermo-plastic material. One web of each package is formed with at least two pockets connected by and bounded by a sealing flange extending outwardly therefrom. The second web which closes the pockets also extends over the sealing flange and the entire interface between the two webs is heat sealed to prevent migration of meat juices. The machine includes a sealing head a...

The apparatus includes an L-sealer and a supply of folded film which is fed across a horizontal table to the vicinity of the sealer, where a product to be packaged is placed between the upper and lower sheets of folded film. The sealer is then operated to hold closed the open side of the film opposite the fold and thus to form a bag which is closed, but not sealed, on three sides. The edge of the table facing the open end of the bag is provided with a vacuum chamber which is operated to remove a...
