Abstract: A film-packaged sanitary tissue paper product with excellent openability includes a bundle of the paper packaged with a flexible resin film, and has a dispenser-port-forming region defined by an easy-tear line in a loop in its top face. The easy-tear line which defines the boundary of an end of the region having a perforated line wherein modified cut areas each having major cut part and a dogleg peripheral cut part contiguous thereto at 90° or larger, are arranged with uncut areas interposed. A peripheral cut part of one modified cut area overlaps an end without a peripheral cut part of the adjacent modified cut area, on the outside and/or the side closer to the center of the region, such that the peripheral cut part or the end of the modified cut area located on the outer side of the region is positioned on the outer side of the region.
