How Dunnage Bags Prevent Pallet Load Damage in Transit

Dunnage bags are the perfect solution to secure your loads in transit. No matter how you place your loads in a container, there will always be gaps between the cargo and the side walls. There will also be several voids between the pallets themselves. This will result in freight movement forward to backward during transit.

What are Dunnage Bags?

Dunnage bags are an excellent way of stabilising and securing cargo during transportation, whether by road, rail or ship. These bags are placed in the void in-between the cargo so that they don’t crash into one another. Almost every type of cargo can be secured with the help of dunnage bags including palletised cargo, barrels, cases, crates and metal coils.

Dunnage bags are typically made from an elastic film that can be filled with air. When the bag is inflated and at rest, it bears the weight of the package upon its cushioning. However, when dynamic loads are placed, their weights are absorbed by the compression of the cushion.

Inflatable Dunnage Air Bags are made of Kraft paper with an inner layer of woven PP cloth for additional resilience and durability. The inside bladder is made of PA film, which enables quick inflation and deflation. An innovative inflation valve seals the bladder that can be inflated with an air-inflator gun.

Our dunnage bags are 1000mm wide and 2200mm in length.

Why use Dunnage Bags?

Dunnage cargo air bags are a more economical and efficient way of bracing and blocking cargo as compared to other, costlier methods such as lumber planks and strap-downs.

Inflatable dunnage bags allow more efficient utilisation of container space. This is possible because dunnage air bags allow double and triple-decking of skids for achieving maximum cube utilisation. That helps improve the load factor and lowers the cost of transportation.

How to Inflate Dunnage Bags

Dunnage air cushion bags are inflated with the help of a fast-inflation gun which is easy to handle. The Omni inflator gun comes with features such as finger-free design, lock ring and air pressure adjustment button.

Dunnage Bag Inflation Instructions:

1. Keep the ‘lock ring’ of the locking device at the head of the inflator in an upper position (see the correct position below).

2. Aim the locking device of the inflator at the valve. Note that the pin in the middle of the locking device should fit into the column at the centre of the valve.

3. Now hold the valve base from the back against the inflator. Avoid touching the valve’s sealing bottom or leave some space for it, then press the inflator against the valve in a swift motion. The ‘lock ring’ of the locking device will move down to lock the valve tight.

4. Press the switch button on the air-inflator gun to start inflating.

5. After inflation, pull the ‘lock ring’ to release the valve from the inflator.

6. Release the switch button to cut off the air supply.

7. Cover the dust cap on the valve, for added protection.
