Dunnage Bags - protect your Cargo

Dunnage Bags - protect your Cargo

Dunnage bags are essential for protecting cargo in transport, minimising the risk of product damage due to shifting during transit. Research has shown that 20% of customers return or make claims about damaged products when they arrive - a problem dunnage bags can prevent from happening.
Commonly known as container airbags, these inflatable void fillers guarantee secure shipment and happy end-point customers who receive their orders without any issues.

The sheer amount of movement that a shipping container experiences during transit can put it at risk for major damage. However, using securement such as dunnage bags can significantly reduce the extent to which containers are exposed to harm while travelling across oceans and continents - from New Zealand all the way to customers in America, China or Europe!


When choosing dunnage bags as a solution to secure your cargo, there are several questions that should be asked first.

What product is being packaged and what type of bag should be used?

Additionally, consider if the inflators fit with all types of bags and whether or not voids in size require special attention. When packing containers for shipment it's important to remember; will shifting cause damage to products or container sides? As well, does this pose any risk when opening them at their destination - Health & Safety must always remain top priority.

Once the decisions have been reached, dunnage bags or another securement method provide an ideal solution. In this case, it appears that the secure and reliable option of a dunnage bag offer all necessary requirements for safe transportation.

What are the Different Types of Dunnage Air Bags?

Polywoven Air Bag Versus Paper (Kraft) Dunnage Bags.

If you’re looking for the perfect packaging solution, Polywoven Air Bags and Paper Dunnage Bag are here to answer your needs. Boasting an airtight polyethene inner bladder and strong, durable outer layers of either woven polypropylene or kraft paper depending on your requirement – these bags can help protect heavy cargo from even the harshest weather conditions while being lightweight enough to easily be loaded/unloaded. Best yet? They come in multiple sizes and offer a cost-effective way of shipping dry goods with environmental friendliness top of mind.

Now that you know the basics, it's time to figure out which Dunnage Bag will best suit your needs. Consider things like what mode of transport is being used for shipping, the type and weight of cargo involved as well as any potential environmental conditions during transit - all these factors should be taken into account when selecting a suitable bag! For heavier shipments up to 60 Tonnes in containers, bracing using dunnage bags may provide an ideal solution.

When it comes to making sure your load is supported safely and securely, the thickness of ply matters. Two-ply can support up to 20 tons, four-ply a max of 30 tons when increased strength is required while six or eight-plies will handle loads of 50 & 60 respectively.

Choosing the right Dunnage Airbag for your cargo can be a tricky process. Depending on how you're shipping (truck, sea container, railroad car or vessel) different levels of airbags are required - from two-ply to higher level protection options like Level 1 and 2 bags. Plus there's also factoring in load weight when selecting an appropriate bag size; ideally measured by taking into account any available voids between items being shipped alongside distance measurements too! If this all seems overwhelming don't worry – just reach out to your ANC Distribution Representative who will guide you through finding the perfect fit for your transportation needs.

Choosing the right dunnage bag for your application is a crucial step. Take time to measure and consider all elements, such as space available and product weight, before making a decision - after all it's essential that you get it just right!

To ensure a safe and secure shipment, it is important to take into account proper dunnage bag placement. Be sure the bag itself doesn't come in contact with any sharp surfaces of pallets or containers - instead, keep them off the floor where they won’t be punctured by splinters or other sharp items. For optimal performance when inflating each side must have at least 60% surface area coverage; if your chosen bag isn’t large enough for this, opt for a larger size option rather than trying to fold it in half! Keep inflation pressure below 90% so that your dunnage bags are performing their cushioning task effectively. When securing a load, dunnage bags are often used. It's important to remember that if one bag is too small for the job, you should never try stacking two together - it won't provide enough stability and can result in items slipping out of place.

Dunnage bags create friction between the product and walls of containers to keep loads secure. Selecting an appropriate dunnage bag is just one step, choosing a compatible inflation device is also key. Open valve styles rely on their cap for containment whereas star-top valves can be deflated by pressing down then rotating left to open them up. ANC Distribution's dunnage bags are not just a one-off solution; they can be reused repeatedly with the right deflation techniques.

What product is being packed?

From cheese to tinned products, soft goods are the perfect fit for efficient packing. Steer clear of heavier items such as bricks, timber, and steel - they don't work well with dunnage bags.

What type of dunnage bag should I use?

It all depends on what type of items you’re shipping and how much they weigh—dunnage bags can provide protection against movement, vibration, or shock throughout transit. Finding the appropriate one will ensure safe transport.

Do all inflators fit all dunnage bag types?

No, to guarantee safety and optimal performance, it's important to use inflators made either by the manufacturer or a trusted supplier. Investing in specially recommended tools can ensure your rides are as enjoyable - and secure - as possible!

What size void are you dealing with?

When securing cargo with dunnage bags, it is important to note that each bag has a recommended load capacity. Inflation pressure should never exceed 90%, as this could prevent the cushioning effect of the dunnage bag from working properly. Additionally, using two or more bags together will not suffice if you find your current one is too small - select a smaller size and replace instead!

Uncertain if the load shift in your container will cause damage or compromise someone's Health & Safety?
