PROBLEM TO BE SOLVED: To provide a multi-chamber packaging container which has two or more chambers and is capable of keeping a liquid material and a solid material in a mutually separated state before use and mixing both the materials integrally within the container in use.SOLUTION: In a multi-chamber packaging container, a bag body is divided into two or more chambers by heat-sealing the outer surface side of a two-folded partition film with the inside surface of the bag body heat-sealed on the right, left, upper and lower sides, and each chamber is filled with contents. The strength of the heat seal between the partition film and the inside surface of the bag body is lower than the strength of the heat seals of the right, left, upper and lower sides of the bag body. The outer surface side of the partition film is heat-sealed with the inside surface of the bag body in a middle part between the crest side of the two-folded partition film and the side opposite to the crest side, and the inside surface sides of the two-folded partition film are not bonded together. |
