“…In recent years, sustainability initiatives have targeted the reduction and light‐weighting of primary and transport packaging materials 18,19 . In addition to the reduction in packaging materials, stretch film, the most commonly used load stabilizer, has seen a trend in gauge reduction 20 . The combined efforts of package source reduction and film downgauging have led to unit load systems being more vulnerable to horizontal forces than ever before.…”

“…18,19 In addition to the reduction in packaging materials, stretch film, the most commonly used load stabilizer, has seen a trend in gauge reduction. 20 The combined efforts of package source reduction and film downgauging have led to unit load systems being more vulnerable to horizontal forces than ever before. As this trend is likely to continue, it is imperative to fundamentally understand these types of events to provide a means of evaluating unit load performance as it relates to load stability.…”

Current laboratory tests designed to evaluate package and unit load systems focus strictly on the intensity of vertical orientation. However, due to an increased demand for source reduction and the light-weighting of packaging components, unit loads are becoming more susceptible to the horizontal forces encountered during transport.Understanding the field measured acceleration levels is critical to developing accurate laboratory test simulations to examine unit load rigidity. This paper uses horizontal acceleration data collected from two air ride suspension trailers to quantify the rise times and steady-state accelerations levels experienced by the vehicles in the longitudinal (braking) and lateral directions. These characteristics are essential in establishing test methods that accurately reflect field measured events. The results show that the rise times experienced by larger transport trailers are longer than previous reports using smaller trailers. The larger transport vehicles from the present study showed lower decelerations and accelerations in braking and lateral moving events, respectively, compared to smaller transport vehicles. Regardless of travel direction, the deceleration and acceleration levels are right-skewed, with most of the events falling below 0.33 g.
