PROBLEM TO BE SOLVED: To provide a case for a packaging bag having the high permeability between the inside of the case and the inside of the packaging bag to be stored in the case and the outside.
SOLUTION: In the case for the packaging bag having a plurality of hole parts to be communicated with the inside, an opening part for ventilation is formed in each of side parts opposite to each other. The spacing between an inner surface of the case for the packaging bag and an outer surface of the packaging bag is preferably changed as being farther from the opening part. Further, the spacing between the inner surface of the case for the packaging bag and the outer surface of the packaging bag is preferably smaller as being farther from the opening part at least in a part thereof.
