PROBLEM TO BE SOLVED: To accurately perform positioning of a packaging material and to accurately determine a position for sealing, a position for cutting or the like. SOLUTION: A packaging container is prepared by forming a mark for detection on the surface of an outside and performing a specified processing in a filling machine. The mark for detection is equipped with a plurality of mark elements m1-m7, and at least a specified mark element among respective mark elements m1-m7 is formed of a magnetic material. As the mark for detection is equipped with a plurality of the mark elements m1-m7, and at least the specified mark element among the respective mark elements m1-m7 is formed of the magnetic material 10, the mark for detection is magnetically detected. Thereby, a design printed as an external decoration on the surface on the outside of the packaging material 10 is not erroneously detected as the mark for detection for positioning.
