PROBLEM TO BE SOLVED: To suppress falling off of a packaging film for packaging a container body from the container body when a bag is broken or the like in a package. SOLUTION: In a package 10 for packaging the container body 12 for storing a content with a heat-shrinkable film 20, a part packaging the barrel part 16 of the container body 12 and the surrounding of the bottom part 18 of the heat-shrinkable film 20 are heated, but a part for packaging a spout part 14 is not heated. Therefore, the heat-shrinkable film 20 has a tightly sticking part 22 sticking the contour of the container body 12 by heat-shrinkage, and a separating part 24 separated from the contour of the container body 12 as heat-shrinkage is not performed. The position P of a perforation 28 is set nearer to the separating part 24 than to a position M being the position of the maximum outer peripheral diameter which is an inflection point of the barrel part 16 of the container body 12, and at a position nearer the tightly sticking part 22 side than the position S being a boundary part between the tightly sticking part 22 and the separating part 24.
