ABSTRACT:
When using web-shaped packaging material in which the rear end of a packaging material is spliced to the front end of a next web-shaped packaging material, in order to continuously operate the filling machine for paper container, notches are provided on a corner portion of the paper spliced portion around the metal layer. Even if a paper spliced portion is included in the web-shaped packaging material, in the filling machine seal insufficiency is not generated in the longitudinal seal of the paper spliced portions, and an interruption due to the broken part of continuous operation is prevented.
