Effect of corrugated cardboard shape on the packing damping properties

The present work objective is searching for such forms of the cardboard corrugation which could effectively absorb the impact load on a cardboard sheet, both vertical and horizontal. The research subject is the depreciation efficiency of the cardboard package with a cell and an alternative (with MS-profile) structure by the action of shock across and along the honeycomb. Measurement and comparation of the deformation rate, as well as the shock absorption capacity of the sample cartons with the standard and alternative MS-corrugation are considered as the investigation tasks. The samples were under the impact force. Shock absorbing properties of the multilayer cardboard packaging in size of 127 × 127 mm were evaluated under the following conditions: drop height, 610 mm; impact speed, 3.5 m/s; falling weight, 12.5 kg; pressure load, 340 kg. In this case, pressing force, impact energy, deformation value is recorded. As a result of the experiments, it was found that a three- and five-layer sample with MS-profile has better shock absorbing properties (as compared to a standard cellular cardboard of the same thickness). The application of seven- and nine-layer cardboard with MS-profile is inappropriate due to a minor advantage over a three- and five-layer sample.
