Abstract
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 air from the bag, whereupon the L-sealer is operated to complete the sealing of the bag and the severing of the bag from the film supply.
