Impact tests were carried out on double arch corrugated paperboard. The dynamic impact curves of the double arch corrugated paperboard in the impact height of 0.3, 0.4, 0.6 m and under the relative humidity of 50%, 65%, and 90% were analyzed. Meanwhile, the energy absorption diagrams were established. The experimental results showed that, with the increase of relative humidity, the best energy absorption points of the double arch corrugated paperboard offset to the lower left and the ability of the unit volume absorb energy decreases; when double arch corrugated paperboard fully crushing, the best energy absorption points are not changing.
