Study and characterization of palletizing films used in the field of freight transport

Effective product protection during transportation is a crucial issue for many industries. This study focuses on the use of linear low-density polyethylene (LLDPE), a commonly used packaging material for palletization. The goal is to deeply understand the properties and behavior of this material, especially in transportation-related stress contexts.

Research Objectives

This study aims to deepen the understanding of packaging materials, particularly LLDPE, under transportation constraints. The objective is to optimize packaging parameters to ensure maximum protection of goods while reducing costs and environmental impact.

Research Methodology

The adopted methodology includes the preparation and characterization of LLDPE film samples, applied manually and mechanically. Tensile and relaxation tests were conducted to measure mechanical properties and evaluate residual stresses, as well as to examine viscoelastic behaviors under transportation stress.

Results and Analysis

Tests revealed distinct tensile properties between manually and mechanically applied films. Film relaxation showed significant differences in terms of residual stresses, which have direct implications for load stability during transportation.

Conclusions

This study synthesized the mechanical and viscoelastic properties of LLDPE films, providing valuable insights to enhance load stability during transportation. These findings can help optimize packaging practices and reduce the risks of damage during transit.

Future Research

Further research is suggested focusing on the effects of dynamic stresses and creating a defect library for packaging films. Such studies could provide deeper insights for developing even more effective packaging solutions.
