Corrugated packaging models and theories are well-established under static load conditions, however, very few studies can be found in the literature dealing with the behaviour of corrugated boards under impact conditions, which is critical in e-commerce distribution. Packaging capacity of energy absorption and the acceleration peak provoked during the drop or shock event are the key factors to assure the impact does not cause damage to the products. This study describes cushioning properties of corrugated boards in edge crush disposition and proposes a predictive model, experimental methods, and tools to assess its dynamic properties. The proposed model is based on static edge crush test theory adapted to impact conditions through relations with static properties of paper. This novel model will allow the estimation of energy absorption for packaging solutions that rely on this deformation mode.
•Behaviour of corrugated boards under impact conditions is critical in e-commerce distribution.•The dynamic behaviour of the corrugated boards was studied using a novel impact hammer machine system.•The material behaviour was measured, focusing on the dynamic effects during the fall of the impact hammer.•An experimental data condensation was performed to interpret the dynamic properties.•A semi-empirical approach was proposed for the dynamic behaviour of corrugated board panels.
