(57) [Abstract] [PROBLEMS] To provide a packaging container in which strength does not decrease. SOLUTION: A first panel P1, a second panel P2, a third panel P3, and a fourth panel P4 each having rectangular portions a1 to a4 forming sidewalls are heat-sealed to the first panel P1, and vertically. A fifth panel P5 that constitutes a seal portion and a rectangular portion c3 that constitutes a bottom wall of the third panel P3 are formed adjacent to each other, and include a main seal portion s6 and a reversal seal portion r6, and the first panel It has P1 and the 6th panel P6 heat-sealed. Then, the sixth panel P6 and the first
The panel P1 is heat-sealed with the end surface of the sixth panel P6 facing the outside of the packaging container. In this case, the end surface of the sixth panel P6 is not exposed to the inside of the packaging container and is directed to the outside, so that it does not come into contact with the contents. Since the contents do not penetrate into the packaging material 11 from the end surface of the sixth panel P6, it is possible to prevent the strength of the packaging container from decreasing.

In the heat-sealed portion with 1, the inverted seal portion r6 is valley-folded, and the innermost layer of the inverted seal portion r6 and the first panel P1.
The innermost layer is heat-sealed. In this case, the sixth
Since the end surface of the panel P6 is not exposed to the inside of the packaging container and is directed to the outside, it does not come into contact with the contents. Therefore, since the contents do not penetrate into the packaging material 11 from the end surface of the sixth panel P6, it is possible to prevent the support material of the packaging material 11 from deteriorating and prevent the strength of the packaging container from decreasing. it can.
