Drop simulation analysis and experimental verification of a certain packaging box
Through theoretical analysis and simulation of the packaging box under drop conditions, stress cloud diagrams and stress-time history curves were obtained during edge and corner drop impacts. The results indicate that the maximum stress experienced by the packaging box is below the material’s yield limit. Drop tests confirmed that the box structure remained intact with no damage or deformation, and the experimental data aligned well with simulation results. The simulation analysis is validated as reasonable, demonstrating that the packaging box design meets the required specifications.

Commercial Blend for Sustainable Future—Study on Degradation and Electrostatic Properties
Interesting alternatives to expensive biodegradable polymers are their composites with natural fillers. The addition of biochar to a blend of poly(lactic acid) (PLA) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) was studied, and the resulting materials were evaluated for their properties and changes during degradation. Introducing biochar as a filler brought a noticeable improvement in electrostatic properties. Surface resistivity decreased from 3.80 × 10[sup.12] for the sample without biochar to 1.32 × 10[sup.12] for the sample with 30% filler content. Degradation tests revealed distinct differences in the degradation profile for composites due to the presence of filler. Composites with a lower biochar content displayed curling crack edges during hydrolytic degradation, and when the filler content reached 20 wt%, PLA loss accelerated. This study suggests that biochar-based composites have potential to be used as sustainable materials with improved properties.
