The first outer indentation and the second outer indentation are respectively positioned on two sides of the inner indentation of the carton sub-board, and the depth of the first outer indentation is greater than that of the second outer indentation. The first outer indentation and the inner indentation are used for realizing that the sub-board is continuously bent to a folded state along the bending direction in the use state in the recycling and flattening process, and the second outer indentation and the inner indentation are used for realizing that the sub-board is bent to form a bent part when being recycled again or is continuously bent to the opposite direction of the bending direction in the use state until the paper board is horizontally laid and vertically placed.
The cross sections of the inner indentation and the outer indentation are of U-shaped structures. The middle part of the indentation of the structure is of a circular arc structure, so that the honeycomb paperboard can be compressed or expanded to a larger extent in the bending process of the indentation.

In this embodiment, the two sides of the inner indentation are provided with pre-pressing lines, and the depth of the pre-pressing lines is smaller than that of the inner indentation. The pre-pressing line is arranged to perform indentation with shallow depth on the honeycomb paperboard in one step, so that the honeycomb paperboard is softened in the pre-pressing line area, and then the inner indentation with deep depth can be performed in the area, thereby avoiding line explosion. Based on the principle, the pre-pressing line can be arranged on one side of the inner indentation.
