The vibration property of BC corrugated paperboard was investigated by sine vibration tests under different environmental humidity, and the vibration transmissibility curves, natural frequencies, vibration transmissibility, damping coefficients and damping ratios of BC corrugated paperboard were obtained. Then corresponding single factor relation models against environmental humidity were established by using regression analysis method. The experimental results showed that environmental humidity has obvious effect on vibration transmissibility of BC corrugated paperboard.
