Observation of Stacked Corrugated Paper Boxes’ Motion Under Vibration Simulation

Abstract

The unitized loads are the major form of the packed product transportation, and most of the cases the packages are fixed to the pallet with straps, stretch film or these combinations. During transport, various vibrations occur in the packaging-product system, which can damage the products. Many of studies focus on the nature of these vibrations, but the vibration varies between the layers of stacked packaging is not fully researched. This paper focuses on the different motion of the layers in the unitized loads in function of the fixing mode to the pallet. Therefore, multiple unitized loads were built from the same corrugated paper boxes in three layers with various fixing mode, to measure each layer motion during vibration. To carry out the simulation procedure, acceleration on each layer was recorded under sine and random vibration simulation. The recorded data shows, which layer motion is the most disparate from the excited motion, which fixing variant caused this difference.
