Unit Load Containment

During transportation, the unit load experiences a variety of horizontal shock impacts and vertical vibrations which can cause the unit load to become unstable or the packages to be damaged.

Using the appropriate load stabilizing method is essential to ensure that products survive the hazards of physical distribution. Virginia Tech’s distribution lab is equipped to use and investigate the latest load stabilizing methods, including stretch wrap, strapping, slip sheets, palletizing adhesives and more.

We have a research grade stretch wrapping equipment that can simulate any stretch wrapping method commonly used in the industry.

We are also fully equipped to conduct a detailed evaluation on the performance of stretch films.
