To provide a packaging bag that eliminates need to house plural types of contents in separate packaging bags and which can be used easily, wherein plural types of contents are separately housed in each partitioning space of a single packaging bag so as to be mixed together upon being used. Thus, there is provided a packaging bag made of a synthetic resin film, wherein a layer constituting an inner surface is formed of a blend of straight-chain low-density polyethylene resin and polybutene-1 resin, and an internal space of the packaging bag is partitioned by a partitioning heat sealed portion that is parallel with opposite heat sealed portions perpendicular to a film flowing direction and which is narrower than the opposite heat sealed portions, thereby forming a plurality of housing spaces.
