You are moving food, automotive parts, industrial equipment or consumer goods, dunnage play the role in protecting the freight throughout the transportation, storage and distribution.
Products face the number of risks as they move through the supply chain. Freight shifts in transit, moisture seeps and pallets collapse into packaging and fragile items break before reaching the destination. Even the minor damage can cause costly returns, complaints, and lost revenues. This is why the business relies on the dunnage in shipping.
Whether you are moving food, automotive parts, industrial equipment or consumer goods, dunnage play the role in protecting the freight throughout the transportation, storage and distribution. In simple terms, dunnage is the materials used to secure, stabilize and separate the freight during handling, storage and transportation.
Dunnage meaning in shipping is materials used to secure, separate or support cargo during transportation and storage. It helps to prevent the freight damage caused by shifting, vibration, compression, moisture and impact while products move through the supply chain.
The financial impact of inadequate freight protection is significant. Product damage is accountable for an estimated 34% of packaging-related returns, whereas the e-commerce return rates range from 20% to 30%. For truck freight, cargo should also be secured to withstand forces created by braking, acceleration, and turns, up to 0.8 g in the forward direction and 0.5 g rearward and laterally under U.S. cargo-securement performance criteria. The right dunnage help you to control cargo movement, reduce avoidable damage, and support safer shipping operations.
There are various types of dunnage solutions available. The right dunnage type depends on the factors such as the product type, vehicle, transportation method, storage requirements, sustainability goals and budget. It is suggested to choose the right dunnage material to protect goods throughout the supply chain. Here are the different types of dunnage
