ABSTRACT:
A method of forming, filling and sealing a reclosable package with a slider activated zipper wherein a base film moves longitudinally to a filling station and, in a moving direction, away from said filling station. At the filling station a product is fed onto the base film. As the base film carrying product is moved from the filling station, a zipper with a slider attached is fed onto the moving film in the moving direction of the base film. The zipper has a first profile and a second profile, each of which has an attached web extending away from the slider. A top film is applied over the base film and the first profile web is sealed to the base film and the second profile web is sealed to the top film. The package is completed by transversely cross-sealing the base film and the top film together on opposite sides of the product. The base and top films may be formed from the same sheet folded over or may be formed from separate sheets.
