PROBLEM TO BE SOLVED: To provide a body frame and a packaging box which can improve compression strength (concentrated load resistance) while achieving reduction in manufacturing cost.SOLUTION: A body frame 20 is used for a packaging box 1 having a pallet part 10 in which girder parts 12a-12c are formed on the undersurface. The body frame 20 comprises: a body frame body 21 which is disposed in the upper part of the pallet part 10 and in which an end panel formed along a Y-axis direction that is a longitudinal direction of the girder parts 12a, 12b, 12c is formed; and reinforcement parts 22a, 22b fixed to the end panel. The end panel is a surface to which a load is easily applied from the girder parts of the packaging box of the upper stage when the packaging boxes are stacked. Thus, by fixing the reinforcement parts 22a, 22b on the end panel, it is possible to achieve reduction in manufacturing cost and improve compression strength.SELECTED DRAWING: Figure 1 |
