What are Dunnage Air Bags?

Dunnage Air Bags are an economical way to brace your product while in transit. Load shifting is the #1 cause of damage, which can be very costly. Dunnage Air Bags are made of 2,4, 6, or 8 plies of 80 lbs Kraft Extensible paper. Inside the bags are lined with a 3 mil polyethylene bladder which meets or exceeds the requirements of Table C, Rule 40 of the Uniform Freight Code. The paper exterior protects the inner poly layer and holds the bag in place between your product.

Dunnage Air Bags are used in Truck, Rail Car, Container, or Intermodal Shipments. In most truck shipments, 2 is recommended. For railcar and overseas shipments, a heavier 4, 6, or 8 ply is recommended.
