Dunnage Bag Types
2-Ply Dunnage Bags
Constructed of 2 plies of 80 lb. extensible Kraft paper or equiv-alent, Which meets or exceeds the re-quirements of Table C, Rule 40 of the Uniform Freight Code. Inner bladder constructed of 4 mil. poly-ethylene. Maximum recom-mended inflation pressure is 3 psi. Production date is stamped on each unit.
Used in container and truck shipments for lighter loads, as with the 4-Ply bag. The load is secured by forcing the last 2 or 4 pallets to the sides of the truck creating frictional drag.
4-Ply Dunnage Bags
Constructed of 4 plies of 80 lb. extensible Kraft paper or equivalent, which meets or exceeds the requirements of Table C, Rule 40 of the Uniform Freight Code. Inner bladder constructed of 4 mil. co-extruded polyethylene or equivalent. Constructed to meet AAR requirements. Maximum recommended inflation pressure is 4 psi. Production date is stamped on each unit.
Rail Car Uses
Used in railcars to fill length-wize void and crosswise bracing in doorways when weight of load is less than 30,000 lbs. per bag.
6-Ply, 8-Ply Dunnage Bags
Constructed of 6 plies of 80 lb. extensible Kraft paper or equivalent conforming to the physical requirements of Table C, Rule 40 of the Uniform Freight Classification. Maximum recommended inflation pressure is 6 psi. Production date is stamped on each unit.
The primary application for the 8 Ply bag is for the shipment of roll stock in rail cars. The construction of the 8-ply bag is identical to the 6-ply bag with the exception of the number of plies used in its manufacture. Maximum recommended inflation pressure of the 8-ply bag is 10 psi. Used in railcars to fill cross-wise voids at doorways where due to severe shipping conditions, a greater amount of protection is needed.
Inflatable Air Dunnage Bags
Disposable inflatable dunnage (air) bag is a flat tube constructed of heavy kraft paper and a sealed inner plastic liner. It is inflatable through a valve. As air is injected into the plastic liner, the bag thickness increases exerting an outward force.
A dunnage (air) bag consists of two major components. The first is the body of the bag, made of various plies of kraft paper. The paper plies provide the strength to retain the air pressure and prevent stretching or enlarging of the bag walls as it is inflated. The second is the inner plastic liner. This retains the volume of air and prevents leakage. The liner or air bladder is constructed of polyethylene film. The valve liner ends are carefully heat sealed to complete the airtight closure.
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.
Benefits to using a Dunnage Air Bag system:
Economical - provides savings when compared to other products. A single dunnage air bag can sometimes brace an entire load.
Reduces or Eliminates Longitudinal Movement or Cargo - Load shifting is the major cause of transit damage. By correctly bracing the load, damage is eliminated.
Ease and Speed of Application - Compressed air does most of the work, not you. The bags can be installed in minutes with very little physical labor involved.
Easily Deflated and Removed - By puncturing the bag with a sharp object, the bag will deflate and can be removed.
