The invention provides a cylindrical packaging body which has a clamping part with excellent sealing performance. The cylindrical packaging body is provided with: (A) a filling material; (B) a cylindrical base metal thin film filled with the filling material and configured by a polyvinylidene chloride resin thin film, through conducting bunching packaging on the two end parts in a long edge direction; (C) a reinforcing belt which is welded to the base material thin film so as to wind and cover the part of the base material thin film that is subject to bunching packaging and is made of a polyvinylidene chloride resin thin film, characterized in that: a short edge of the base material thin film prior to the bunching packaging has a hot shrinkage rate RB-TD below 100 DEG C put between the range of 10.0-18.9 percent, the extraction rate of acetone is less than 9.0 %, and thorn energy is more than 2.1mJ under 120 DEG C.
