A new overlapping technique was proposed in this study to mechanize and automate overlapping technique for honeycomb paperboard. The established new technology was then applied to study the properties of edge loading of overlapped honeycomb paperboard , i.e., the load bearing condition of edge-punctured. Five key processes of new overlapping technique for honeycomb paperboard were gained including crush， crease， sizing treatment， edgefold and side pressing. Comparative experiments were carried out for the new technology processed honeycomb paperboard and manual processed ones, then the maximum capability of edge loading were tested and analyzed for four different thicknesses of the two overlapping technique under concentrated load. Our results showed that under concentrated load, the maximum capability of edge loading of honeycomb cardboard made by existing manual process was only related to the material of overlapping paper, but with few impact from the thickness of honeycomb paperboard; however, that of honeycomb cardboard made by the presented new wrapping technology was not only related to the thickness of honeycomb paperboard but also correlated with the material of overlapping paper. Maximum capability of edge loading of honeycomb cardboard made by the presented new wrapping technology were greater than that of using the existing manual process． Maximum capability of edge loading of honeycomb cardboard was greatly improved by the presented new wrapping technology. In addition, the new technology is easy to mechanize and automate， which can greatly improve the productivity efficiency and quality through postprocess of honeycomb cardboard.
