Shock Absorption Characteristics and Optimal Design of Corrugated Fiberboard Using Drop Testing

The application of corrugated paper to buffer packaging has increased with the rise circular economy. dynamic curve is key designing structure but requires multiple testing by small- and medium-sized enterprises (SMEs) without resources. In this study, we propose drop perform a fractional factorial experiment establish regression model impact strength through experimental data. analysis results show that static stress, falling height, material thickness are variables strength, an prediction (R2 = 94.1%) was obtained. Model verification using package design personal computer showed measured values fell within estimated 95% confidence interval. These indicate SMEs can use proposed procedure improve minimal
