International Dunnage bags are the convenient way to protect goods from being damaged during shipping. Our bags have an outstanding load stabilizing capacity and resistance to load shifting; International Dunnage bags can withstand tons of pressure. 

The durability of International Dunnage bags lies in their well designed structure. They are composed of an air tight polyethylene inner layer with an inflating and deflating valve and a strong and elastic poly woven outer layer. 

Bag Types

Standard Level Bags

Standard bags take the shape of a pillow when they are inflated. They are used between the voids that are up to 12” (30cm) wide. International Dunnage standard bags are available in four different levels: L1, L2, L3&4, and L5 with a wide range of dimensions and are AAR verified. L1 bags are be produced with our patented Safe-Lock, Jet-Flow or Combo valves. For higher levels, we use Safe-Lock or Combo valves.

Bison bags also take the shape of a pillow when they are inflated. They are designed for light duty mainly used in Truck shipments, and they are more economical compared to Level 1 bags. They are not AAR verified.

Transportation Method: Truck - Vertical or Horizontal Voids – Bison bags are NOT for rail use

Max. Air pressure: 2-3 PSI

All truck and container shipments consisting of glass bottles, paper products, drums, furniture, beer, wine, and dry products

Paper Equivalent: 2 ply paper bags

Transportation Method: Truck/Container - Vertical or Horizontal Voids

Max Air pressure: 2-3 PSI

All shipping containers - either piggyback (container or trailer on the Railroad) or for ocean transport; same as for Level I

Paper Equivalent: 4 ply paper bags

Transportation Method: Truck/Container/Ocean - Vertical or Horizontal

Max. Air pressure: 6 PSI

Most railroad applications use the Level III - IV bags. They are for rail cars with load weights from 75,000 LBS to 205,000 LBS which includes paper rolls, plywood and bricks.

Paper Equivalent: 8 ply paper bags

Transportation Method: Rail/Ocean – Horizontal or Vertical Position in Void

Max. Air pressure: 8 PSI

Railroad use for heavy applications. They are for rail cars with load weights exceeding 205,000 LBS.

Paper Equivalent: Level 5 has no paper equivalent as paper  bags are not capable of meeting the strength requirements of the AAR.

Transportation Method: Rail/Ocean - Vertical or horizontal position in void

Max. Air pressure: 10 PSI

Square Bag

The International Dunnage square airbag was designed and created to serve as the primary function of bracing products, our standard sizes fill gaps from 17 up to  25 inches width, which cannot be filled with a standard dunnage bag. 

* Square Bags can be used on rail once but not twice. 

The International Dunnage square bags brace loads without the need for additional dunnage material. Made with moisture resistant material and an extremely durable outer shell, the International Dunnage square bags are also AAR certified. They are not made for heavy duty purposes.


  • Air dunnage bags cannot be used as primary load securement in hazmat shipments; however, they can be used for secondary load securement.
  • Air dunnage bags cannot be used in air cargo shipments due to the changes is air pressure at high altitudes.


Bladder Types

After years of experience, International Dunnage has created a super tough bladder bag. The combination of two to four layers of Polyethylene Film on each side of our bags offer superior protection leaking caused by pin holes during manufacturing of extruded films, minor scratches or cuts and user handling. These extra layers of protection ensure successful loading and durability of airbags.

The new multilayer bladder bags have been tested under tough conditions and show no signs of leakage. They are manufactured 100% by our fully automated state of the art machine eliminating production defects caused by human error.

Two layers of film are used oneach side for our lighter duty bages while four layers are used for each side of the heavy duty bags.

The mono layers are made from a co-ex film which have a different thickness depending on which dunnage bag level is used. All of our standard products are produced with mono-layers as standard.

Valve Types

Combo valves are designed as a combination of Jet-Flow and Safe-Lock valves which have the fast fill advantages of Jet-Flow and the durability of Safe-Lock valves. This valve is spring loaded and can be used for all levels. They are reusable and easy to handle. All valves are 100% leak tested during production and have passed compression testing under severe climate conditions.

Combo Inflator tips are designed to fit Combo valves and can resist high pressure. They easily snap on to the valve by pressing against a wall and designed to be used with our Mini Jet Flow and Monster air guns; however, other air guns may also be used by connecting an air hose. Combo Inflator Tips are made out of hard plastic materials. Aluminum version is also available for heavy duty use.

*Can be used with both Jet-Flow and Safe-Lock air tool

*Snaps and locks onto the valve for airtight hold


Safe Lock valve is a fast fill type and spring loaded.  It can be used with all bag types. When inflating, a "Safe Lock Tip" must be used together with an air gun. 

Inflator Tools

The fastest airgun in the industry which can be used with pencil or digital gauge. It has many advantages:

·         Helps save time and increase productivity.

·         Designed to support hand comfortably.

·         Durable, high impact plastic.

·         Light weight

Mini Jet Flow Air Gun has many advantages compared to other fast fill guns. The weak points of all fast fill guns have been evaluated and improved in this new design. Mini JF Gun will make the inflating job enjoyable.


·         Fits into narrow voids – shorter in length

·         More robust body - supported pistol design

·         Longer life time - made with high performance materials

·         User Friendly - Ergonomic trigger design

·         Better grip – anti-slip handle

·         Twp Insert Options - comes with red (high pressure) & black (low pressure) inserts

The cylinder air gun has an aluminum body to be used in tough conditions. A pencil gauge can be used together with the cylinder air gun to check the air pressure of the bag while inflating.

The cylinder air gun is designed for safe-lock valve inflation system; it also can be used with combo inflation system as well. To inflate bag,  a tip (adaptor) must be used together with the cylinder air gun.



Pistol air gun is the most simple and cheapest air gun solution and must be used with an air tip to inflate air. İt can be used with Safe-Lock and Combo inflation systems.

Vacuum Packaging System

International Dunnage has developed a vacuum packaging system to reduce the transportation and storage costs, by increasing the pallet counts.

This innovation also ensures complete protection of our dunnage bags from dust and humidity during transit and storage.

Pallets & Boxes

International Dunnage bags are packaged in 100x120x110cm carton boxes.

Which are placed on 100x120cm wooden pallets with a four-sided entry to provide faster loading and unloading.

They can be stacked 4 high.
