The work aims to study the effect of different drop times on the creep property of corrugated board, so as to obtain its creep curve. Through the research and experiment on the creep property of the corrugated board under three kinds of constant loads and three kinds of drop times, its creep curve was obtained. Based on the respective analyses, the effect of multiple drops on its creep property was analyzed. Multiple drops had a significant impact on the creep of the corrugated board. When the drop time(s) was/were 1, 3 and 5, the creep strain was respectively 0.29, 0.33, 0.37 mm. The creep strain of corrugated board will become larger with the increase in the drop times.
