Honeycomb cardboard was made with rich mineral paper of 0.16 mm thickness and 202 g/m2 ration. The honeycomb cardboard was tested for flat compression strength, edge compression strength, puncture strength, and bursting strength according to national standards. The results showed that the average lat compression strength, edge compression strength, and puncture strength of the honeycomb cardboard is 628 kPa, 12.1 N/cm, and 6.84 J respectively; the honeycomb cardboard has high bursting strength. It was concluded that the flat compression strength of the honeycomb cardboard is higher than that of traditional fibrous cardboard; the edge compression strength is lower than the national standard; the puncture strength meets the national standard; the bursting strength is excellent.
