The utility model discloses an arc waist type packing box structure. The packing box is composed of a bottom surface, front and rear left and right side surfaces and an upper cover; the front, rear and left and right side surfaces are connected in an integral ring and are surrounded by pre-folding lines. So that each side can be pressed into a flat shape or a three-dimensional shape of the support frame. The upper cover extends forward from the top of the rear side surface to cover the front side surface, and the positioning can be achieved through the positioning portion; wherein the left and right side surfaces and the front and rear sides The pre-folded lines that are connected on the sides are assumed to have a symmetric arc curve; thereby, when the front, rear, left, and right side supporters are in a three-dimensional state, the front and rear sides of the left and right side surfaces will exhibit relatively symmetrical concave arc curves if viewed from the front view. However, from the side view, the convex arc curve is relatively symmetrical, making the overall packaging box extremely innovative, aesthetic and value.
