Experimental Research on Dynamic Cushioning Property of X-PLY Corrugated Paperboard

In order to obtain the experiential formulas and characteristic factors of dynamic cushion curves and provide basic data for utilizing X-PLY corrugated paperboard in transportation packaging,dynamic cushioning properties of X-PLY(A) and X-PLY(B) corrugated paperboard were investigated by drop shock experiments.The results showed that the shapes of dynamic cushion curves of X-PLY corrugated paperboards are always concave and upward;each piece of dynamic cushion curve has only one minimum value point;the waves of shock acceleration are similar to half-sine shock pulses;so X-PLY corrugated paperboard possesses excellent dynamic cushioning property.Moreover,the dynamic cushioning property of X-PLY corrugated paperboard with flutes A is better than X-PLY corrugated paperboard with flutes B.
