PROBLEM TO BE SOLVED: To prevent a booklet from generating a page difficult to read when a packaging member is added to the booldet by bending protective member in two directions of in the longitudinal direction and the right-to-left direction when a packaging bag in which an article such as a liquid is sealed and the protective member of substantially the same dimension are integrated with each other, and added to the booklet. SOLUTION: A packaging bag 1 is formed as a flexible package to be used in packaging an article such as a liquid, a liquid food, a powder and a grain, taking into consideration the watertightness, the chemical resistance, the gas batrier property, etc., and a protective member 2 is formed of a paper, a slip sheet, a corrugated fiberboard, a synthetic resin, etc. A notch 3 is formed on both surfaces on right and left short sides of the protective member 2 so that the protective member 2 can be bent in the vertical direction with the notch 3 as a center. The packaging bag 1 and the protective member 2 are substantially the same in dimension, and when they are integrated with each other, a part of the content in the packaging bag 1 is stored in an inner hollow part 23 of the protective member 2, and a seal part 21 around the packaging bag 1 is above a frame 22 of the protective member 2.
