Air Bags (Container Dunnage Bags) Air Bags, also known as Container Dunnage Bags, are inflatable packaging solutions used to secure cargo inside shipping containers, trucks, and railcars. They fill empty spaces between goods, preventing movement, absorbing shocks, and reducing the risk of damage during transportation. At Impact Wood Packers, we provide high-quality dunnage bags made from durable materials for safe domestic and export shipments.
