Abstract: X-PLY corrugated paperboard is a new-type corrugated paperboard with
three layers of orthotropic corrugated sandwiches structure, and may be
employed to protect products from shock or vibration damage during
distribution. This article deals with the characterization of properties of
X-PLY corrugated paperboard relevant to its application for protective
packaging in distribution, such as dynamic cushioning curves, vibration
transmissibility and frequency curves. The main feature of article is the
evaluation on the dynamic shock cushioning characteristics and vibration
transmissibility of X-PLY corrugated paperboards by a series of experimental
studies on the drop shock tester and vibration tester, the establishment of
experimental formulas of dynamic cushioning curves, and the analysis of peak
frequencies, vibration transmissibility and damping ratios. By using the
fitting polynomial of curve and method of the least mean square, the
experimental formulas and characteristic coefficients of dynamic cushioning
curves have been obtained. From the vibration tests with slow sine sweep, the
peak frequencies and vibration transmissibility are measured and used to
estimate the damping ratios. These works provide basic data and curves relevant
to its application for protective packaging in distribution.
