Cargo Stabilisation

Dunnage Bags for cargo protection

Dunnage bags are a simple and effective way to secure cargo during transport, placed between loads to fill empty spaces and prevent goods from shifting in transit.

By stabilising cargo inside containers, trucks, and rail wagons, dunnage bags help reduce product damage, improve transport safety, and protect shipments throughout the supply chain.

Checkmate provides a range of high-performance dunnage bag solutions designed for reliable cargo protection across road, rail, and sea transport.

What Is an Air Dunnage Bag?

An air dunnage bag is an inflatable load-securing device used to fill voids between cargo. Once inflated, the bag expands to apply pressure between goods, helping keep them securely in place during transit.

They are widely used across logistics and freight operations due to being:

  • Quick to install
  • Lightweight and easy to handle
  • Effective at preventing load movement
  • Suitable for road, rail, and sea transport

STABILISATION & RISK MANAGEMENT

What are dunnage bags?

A dunnage bag, sometimes known as an ‘airbag’ or ‘inflatable bag’ are used to safely secure cargo during transport. Dunnage bags are useful in stabilising and protecting cargo during transport in closed railcars, trucks, sea-vessels and ISO sea containers, as a cost-effective solution.

Dunnage bags are created to provide a high level of cargo security and alleviate the possibility of damage in transit, ensuring your cargo arrives in the same condition as when loaded.

Our dunnage bags have an easy to use ergonomic quick release coupler. The coupler accepts a male Rectus Type 25 fitting and an inflation tool is also available, with a simple-to-read colour-coded gauge that clearly shows the user when the bag is up to pressure.

The valve assembly has been designed to encompass an inflation coupling and deflation vent. To deflate the unit simply turn the brass vent counter clockwise and air will be released from the bag.

Once your cargo has been correctly and tightly packed within the vessel, truck or rail car, dunnage bags can be used to fill any spaces. The deflated dunnage bag will be inserted into gaps or spaces of 30cm, and then inflated to prevent the cargo from moving.

The rubber material that dunnage bags are made from make them high in elasticity, meaning they can fill a wide range of sizes, shapes and spaces, and also provide a cushioning effect to further protect your goods.

Our Checkmate Dunnage Bags come in a range of sizes:

Rubber Dunnage Bags

  • Heavy Duty Dunnage Bag
  • Double-Chamber Dunnage Bag
  • Multi-Chamber Dunnage Bag

 

Woven Polypropylene (WPP) Dunnage Bags

  • Mega Dunnage Bag
  • Lightweight Dunnage Bag

 

Each dunnage bag has been designed to suit all requirements, budgets and applications, including type, weight and size of the cargo, transportation mode, loading practice and void size. Please get in touch with a member of the team by phone, email or filling out our contact form.

Our dunnage bags are built to last. We have units in use that are over 15 years old due to our high-strength, heavy duty materials. This is dependent on how that bag is used, but in the unlikely event the bag should be damaged we can repair the bag at our manufacturing facility in the UK.

You can rest assured our dunnage bags can be relied upon to keep your stowage in optimal condition for years to come.
