Zusammenfassung:The reclosable package or bag, typically formed by a horizontal form-fill-and-seal method wherein a single sheet of web forms a bottom wall and two side walls, includes a notched zipper so that the interlocking elements are not sealed within the side seals. Furthermore, the method to manufacture the package or bag uses a driven band, band sealer to decrease the drag induced to the film by the zipper. An encoder is used to send a signal to the stepper motors to match the film speed. Band sealers are used to seal the zipper onto a continuously moving web. The band prevents the film from sticking to the seal bars.
