PROBLEM TO BE SOLVED: To obviate the possibility of a failure in a sealed part due to the occurrence of positional deviation between an inside and an outside films or a failure in the appearance of a bag when a bag is made of a double film consisting of two sheets of the inside and outside films which are superposed to each other. SOLUTION: A double bag package 1 forms a vertically sealed part 2 at both side edges of a double film which consists of two sheets of an inside film 6 and an outside film 5, both being superposed on each other, and which is cylindrically curved so that its side edges are superposed on each other. The double bag package 1 has an outer bag 1a and an inner bag 1b, both forming a laterally sealed part 3 at their upper portions and a laterally sealed part 4 at their lower portions in such a manner as to extend in an intersecting direction with respect to the vertically sealed part 2, and the inner bag 1b is filled with an object W to be contained. The double film is formed so as to have high blocking properties between the inside face f3 of the inside film 6 and an inside face f2 of the outside film and low blocking properties between the outside face f4 of the inside film 6 and the outside face f1 of the outside film. |
