Abstract: An object is to prevent roughening of a rupture surface of a packaging material (12) that is formed upon opening of a spout (21) through application of an external force. There are provided transport means for transporting a layered packaging material (12) that is formed of a paper substrate and resin films and that has a rupture area (52) at a location corresponding to that of opening means; a seal unit for sealing the packaging material (12); and heating means disposed on the upstream side of the seal unit in the transport direction of the packaging material (12) such that the heating means is opposed to an innermost layer of the packaging material (12) in order to heat the packaging material (12). In this case, after being heated and melted, the resin film of the packaging material (12) is gradually cooled. As a result, thermoplastic resin that constitutes the resin film is crystallized and becomes brittle.
