ABSTRACT:
A method and apparatus for continuously or intermittently and vertically forming, filling and sealing packaging includes an infeed section, a pleating assembly, a forming tube and a sealing assembly. The pleating assembly imparts at least one pleat to the film. The film may be driven and measured at a nip following the pleating. The forming tube receives the film from the infeed section after the pleat has been made. A film tube is formed about the forming tube. The film tube is vertically fed downward to the sealing assembly which imparts seals to the film tube, thereby forming packages. A hole punch punches holes in the film tube. The film travels a film path that includes the hole punch, the forming tube, the vertical seal assembly and the horizontal seal assembly.
