PROBLEM TO BE SOLVED: To provide a packaging machine for a content having a low melting point, etc., which is configured so as to form a bag while filling the content with the low melting point. SOLUTION: Disposed in the bag making section 7 of the packaging machine M is a vertical sealing section 10 devised such that while film material F fed from a film material supplying section 5 is formed into a tubular shape, the content fed from a content supplying section 4 is filled into it. The vertical sealing section 10 is equipped with a filling chute 11 that has a double tube structure composed of an inner tube 12 and an outer tube 13, and a heater device 20 that forms a vertical seal that fuses both side edge parts of the film material F along the direction in which the film F is fed. The filling chute has an empty space 14 defined between the inner and outer tubes 12 and 13, a circulation passage 15 for circulating water is formed. Therefore, a heat insulation effect is yielded by the empty space 14 and the inner tube 12 is cooled. COPYRIGHT: (C)2008,JPO&INPIT
