What is the function of dunnage in transportation?

The function of dunnage in transportation primarily focuses on protecting cargo from damage. Dunnage consists of materials, often cushioning or filler, used to secure and stabilize items during transport. Its role is crucial in preventing movement within shipping containers or vehicles, which could lead to shifts in balance or impact during transit. By securing the cargo, dunnage helps to absorb shock and vibrations, reducing the risk of damage from external forces such as bumps and jostling.

While other options include providing insulation, moisture barriers, or absorbing chemicals, these functions are not the primary objectives of dunnage. Insulation typically pertains to temperature control, moisture barriers relate to preventing water damage, and chemical absorption concerns hazardous materials. Therefore, the key purpose of dunnage remains to ensure cargo integrity by cushioning and stabilizing items throughout their journey.
