PROBLEM TO BE SOLVED: To provide a packaging machine which eliminates disadvantages of a conventional machine that a peak value of a severe opposing pressure when a packaging tube is gripped in the transverse direction in forming a package, generates no wear in a filling circuit member and is free from any disadvantages that a packaging material and a pack formed thereof are damaged by the deflection in the packaging tube and a packaging apparatus interacted with the packaging material. SOLUTION: A filling conduit pipe 5 has a holding flange 20 on an outer surface of each end 11 stored in the packaging tube, the holding flange has a large number of transverse slits 22 splitting to each tab 23, each tab is deflected by the pressure in the tube, and each food passage with the cross-sectional area gradually increased as the increase in the pressure can be formed in the packaging machine.
