Abstract
The current paper is aimed at investigating the mechanical properties and the impact resistance of three common types of packaging materials: Expanded Polyethylene, Expanded Polystyrene, and corrugated cardboard. The purpose of the study is analysing the materials’ behaviour under different stresses and identifying the most suitable material for packaging. A series of compression tests have been conducted for the three materials to find the maximum compressive load, compressive extension, stress and strain at maximum load. The outcomes of the tests suggest that corrugated cardboard had the highest maximum compressive load and the highest compressive stress. At the same time, EPE and EPS showed significant compressive extension and strain at maximum load, which indicated the materials’ capability of energy absorption. To assess the impact resistance of the materials in question, drop test simulation has been carried out in Solid Works. The time history graphs of the von Mises stress of selected nodes helped to identify the distribution of the stresses and understand the materials’ behaviour during impact. It is suggested that for corrugated cardboard the von Mises stress increases steadily, for EPE it is characterised by many peaks, which means multiple deformation cycles, and for EPS the first peaks of the von Mises stress are high, followed by several peak-and-trough cycles. Overall, the results of the study imply that, while corrugated cardboard has the best compressive strength, EPE and EPS are best suitable for the applications, which require absorption of a high amount of energy. As a result, the findings of the research might be used for the selection and the design of packaging materials to enhance the product protection during transportation and handling.
