ABSTRACT:
A horizontal form, fill and seal machine has a hollow forming box into which a continuous film is longitudinally fed from a packaging film supply. The forming box has a top, sides and open inlet and outlet ends. A pair of guide bars extend from the outlet end of the forming box adjacent the forming box sides and extending away from the inlet end. The forming box transforms the flat packaging film into a film envelope that extends about the guide bars and has a product-receiving surface that rests on a conveyor between the guide bars. Sealing bars are provided to join the longitudinal edges of the packaging film together and to form seals across the envelope at package length intervals after each deposit of product onto the product-receiving surface. A zipper attaching mechanism applies zipper to the film upstream of the forming box.
