Dunnage bags, also known as airbags or inflatable bags, are a type of packaging material used to secure and stabilize cargo during transportation. They are designed to fill empty spaces within shipping containers, trucks, or railcars to prevent the movement of goods and minimize the risk of damage.
Dunnage bags are typically made of durable materials such as polyethylene or polypropylene, which are lightweight and resistant to punctures. They are shaped like large inflatable pillows or cushions, and they come in various sizes and shapes to accommodate different cargo configurations.
