Kraft Paper Air Dunnage Bags

High performance extensible kraft paper is an essential component of a paper air dunnage bag. Paper dunnage bags are constructed of 2, 4, 6, or 8 plies or layers of paper.

Paper provides a high coefficient of friction between the dunnage bag and the palletized product. This enables the bag to “lock the load” in place against the sidewalls of the container or trailer improving overall performance, road safety, and load securement.

Frequently Asked Questions

What is an air dunnage bag?

An air dunnage bag is a load securement product used to stabilize cargo in transit and prevent product damage. A paper dunnage bag is constructed of 2, 4, 6, or 8 plies (layers) of paper and a polyethylene bladder. A poly dunnage bag is made of woven polypropylene tapes and a polyethylene bladder. As air is injected into the plastic bladder the bag expands exerting an outward force. Cost-efficient air dunnage bags can be used in rail cars, intermodal containers, sea containers, and dry van trailers.

Why are dunnage bags used?

Each day valuable products are damaged or destroyed in transit due to shifting. Dunnage bags serve to reduce or eliminate product damage by stabilizing loads as they travel over the road, rail or ocean. Dunnage bags fill voids, brace loads, and absorb vibrations, protecting valuable cargo from damage. Dunnage bags are a highly effective, cost efficient form of product protection.

How do dunnage bags work?

Dunnage bags stabilize cargo in transport and prevent product damage by being placed in a void and inflated with air to restrict load shift in transport.

How do I determine what size dunnage bag to use?

The correct size and type of dunnage bag is determined by a variety of factors including the weight of the product, the size of the product, the void size, and the transportation mode.

Please contact a member of our sales team at 817-473-5098 for assistance in determining the right air bag for you.

Please be prepared to provide the following information:

Void Size
Pallet Size
Load Height
Load Weight

What type of equipment is necessary to inflate international dunnage bags?

Air dunnage bags are inflated using the following tools:

Inflator tool
Air Compressor

The proper inflator tool may be specific to the type of air dunnage bag you require. Please make sure you are using an inflator tool that is compatible with the dunnage bag you purchase.

Can dunnage bags be damaged during filling?

Yes, dunnage bags can burst due to over-inflation. In addition, they can burst due to insufficient strength or violent shifting during transit. Please make sure you are using a dunnage bag that is rated for the mode of transit (truck, rail, ocean) and load.
