Abstract

The present invention relates to a method of forming and closing bags, said method comprising steps consisting in delivering closure means comprising at least two complementary strips disposed on respective backing sheets, in delivering a film that is to constitute the walls of the bag, in heat-sealing a first backing sheet of the closure means to the film along at least one of the longitudinal edges of said sheet, with the closure means being angularly positioned transversely to the longitudinal direction of the film, in shaping the resulting film as equipped with the closure means into a tube and in heat-sealing the second backing sheet of the closure means to an opposite face of the film along only one edge of said second sheet.
