What are Dunnage Air Bags?

Dunnage Air Bags are paper bags,constructed of 2, 4, 6, or 8 plys (layers) of paper or gauges of poly material in 5 different levels (L1, L2, L3, L4, and L5), designed with an inflatable internal Polyethylene Bladder.
They are an innovative and simple blocking and bracing tool.

What are they used for?

dunnage-air-bags-duo

Dunnage Air Bags are used to restrain movement of cargo loads in trucks, overseas containers, or railcars. They fill voids, brace loads, absorb vibrations, and protect cargo from in-transit damage, better than any other form of bracing (“dunnaging”)

What are the most common causes of freight damage?

The most common causes of freight damage are related to freight falling forward to backward, and double and triple decked skids bouncing in transit.

What are the effects of shifting loads and damaged freight?

Customers are unhappy. Valuable time is wasted putting the damaged freight back together at destination terminals. The necessity for “Re’s” (Recouping, Restacking, Re-banding, Re-shrink-wrappping, and Re-working the load) adversely affect dock production and strain customer relations .

How has cargo been braced in the past?

Loads have been braced using a combination of empty pallets, 2 x 4’s, and empty cardboard cartons. Shipments which included fragile cargo as part of the overall load necessitated stair-stepping standard freight back-to or away-from the fragile freight.

What are the benefits of using Dunnage Air Bags?

Dunnage Air Bags represent a less expensive means of blocking and bracing than the use of lumber and nails or expensive rubber air bags.

What are the benefits of using Air Bags to the shipper?

The trucking industry is in an ever-changing fight for survival. Fuel costs and taxes continue to climb, insurance premiums soar, wages increase and discounts continue to consume the bottom line. Operational improvements must be made to maintain profit margins. Air Bags will have the biggest
impact on the load factor (a carrier’s largest single expense). One of the primary goals of the shipping Quality process is to improve organizational productivity. Time spent installing Air Bags will be saved at the destination terminals because the carrier can eliminate the “Re’s”. At the same time, better use can be made of container space.

How is this accomplished?

Air Bags permit double and triple-decking of skids, and stair-stepping can be eliminated. With Air Bags, fragile freight can be loaded anywhere in the trailer. Skids can be double or triple-decked, air-bagged either in front of or behind (or both) the fragile freight to achieve maximum cube utilization. Since the use of Air Bags will permit normal loading behind the fragile freight, eliminating the need for stair-stepping improves the load factor and reduces line-haul or transportation costs. And now, faster filling inflation systems using the latest technology and venturi-style inflator tools have reduced inflation times of air bags by as much as 50% or more.
