1. A method of manufacturing a shoulder / nozzle of a tube with a barrier in the shoulder / nozzle of the tube, comprising molding the shoulder / nozzle of the tube, placing the shoulder / nozzle of the fitting in the holder with the end of the nozzle outward, placing a laminated film containing the barrier layer and the polymer layer on top of the end of the nozzle, this polymer layer is facing the inner surface of the shoulder / nose, the introduction of the laminated film in contact with the matrix / mandrel, with the aim of (i) cutting the laminated film to fit it to the shoulder / spout, and (ii) the insert is laminated th film in the shoulder / nozzle. ! 2. The method according to claim 1, in which after inserting the laminated film into the shoulder / spout it is soldered to the inner surface of the shoulder / spout. ! 3. The method according to claim 1, in which the die-cutting of the laminated film for fitting it to the shoulder / nozzle includes two operations, one is the molding of the nozzle hole in the laminated film, and the other is die-cutting of the laminated film to fit it to the nose of the shoulder / nozzle. ! 4. The method according to claim 2, in which the laminated film has a nozzle opening comprising at least one of a circular aperture and a plurality of slots. ! 5. The method according to claim 1, in which there are many stations, while at one station, a laminated film is cut to fit it to the shoulder / spout, and at another station, the laminated film is soldered to the shoulder / spout. ! 6. The method according to claim 1, in which after installing the laminated film in the shoulder / spout, and before soldering the laminated film to the shoulder / spout, the shoulder / spout is fed to the detector to determine the position of the laminated film in the shoulder / spout. ! 7.
