Dunnage refers to materials used to protect and support goods during shipping and storage. It helps prevent damage by filling empty spaces in shipping containers, pallets, or trucks. Common dunnage materials include wood, plastic, foam, and paper. In addition to cushioning, dunnage can also help stabilize items, ensuring they remain in place during transit. Proper use of dunnage is essential for maintaining the integrity of products, especially fragile items like glass or electronics, and is a standard practice in the logistics and shipping industries.
