PROBLEM TO BE SOLVED: To obtain a packaged structure having a superior wrap-around qualification, and a packaging apparatus capable of composing such a packaged structure. SOLUTION: According to the packaging apparatus, a paper roll 14 is transferred in a direction perpendicular to the axial direction of it, and a center seal part 16S is formed along the circumferential surface of the paper roll 14 by a center sealing apparatus. Further, an end sealing apparatus 72 forms an end seal part 16E along the circumferential surface of the paper roll 14. As a result, when the packaged structure 104, manufactured in the way as described above, is to be wrapped around by an outer packaging material to be packaged in it, both center seal part 16S and end seal part 16E can be wrapped around together. Therefore, the packaged structure 104 has a superior wrap-around qualification. COPYRIGHT: (C)2003,JPO
