A filling-packaging body formed to have both such a durability that can withstand a large amount of filled material filled therein and easily unsealing property. The filling-packaging body ( 1 ) is formed by filling the filled material in a three-side seal bag having an overlapped part formed by cylindrically curving a laminated film ( 10 ) and overlapping both side edge parts of the laminated film, a plurality of vertical seal parts ( 2 a) and ( 2 b) (two seal parts are shown) formed at the overlapped part roughly parallel with each other in such a state that a band-like non-seal part ( 5 ) is left at the tip side of the outer surface side-edge part of the overlapped part, and lateral seal parts ( 3 ) and ( 4 ) formed to cross the longitudinal both end parts of the vertical seal parts ( 2 a) and ( 2 b). The laminated film ( 10 ) is formed by interposing a base material layer ( 12 ) for imparting strength to the film between an inner layer ( 11 ) and an outer layer ( 13 ) which are seal layers formed of a low density polyethylene.
