Study on Cushioning Property of Foam-in-Place Packaging Material in Logistics Transportation

In this study, foam-in-place packaging material was used as cushioning material in logistics transportation. Its cushioning property was studied by means of compression test method, mechanical model analytic method and microstructure-based simulation analysis, respectively. It was shown that the micro-structural compression result of the studied material using the finite element simulation method was consistent with that using mechanical model analytic method. The experimental and simulated stress-strain curves obtained were basically identical to each other, indicating that the simulation method could reflect the experimental conditions. The foam-in-place material had a good cushioning capability, and the internal stress and absorbed energy increased correspondingly with the increase of the filled percentage of foamed liquid (PFL), thus affording the larger load.
