<p>A method of forming, filling and sealing a reclosable package with a slider (32) activated zipper (30) wherein a base film (16) moves longitudinally to a filling station and, in a moving direction, away from said filling station. At the filling station a product (14) is fed onto the base film (16). As the base film (16) carrying product (14) is moved from the filling station, a zipper (30) with a slider (32) attached is fed onto the moving film in the moving direction of the base film (16). The zipper (30) has a first profile (36) and a second profile (34), each of which has an attached web (40,38) extending away from the slider (32). A top film (20) is applied over the base film (16) and the first profile web (40) is sealed to the base film (16) and the second profile web (38) is sealed to the top film (20). The package is completed by transversely cross-sealing (60) the base film (16) and the top film (20) together on opposite sides of the product (14). The base (16) and top (20) films may be formed from the same sheet folded over or may be formed from separate sheets. <IMAGE></p> |
