Secure goods during shipment with Dunnage Bag

Dunnage bags are inflatable cushions used to support palletised cargo during shipping. The container airbags can be supplied using various materials, the most popular being paper, vinyl, and poly weaved. Every dunnage bag has an internal bladder that may be inflated and deflated as required. It is incredibly efficient, cost-effective equipment for blocking and bracing products that fill entire pallets throughout the supply chain process.

The dunnage airbags are positioned between each pallet when palletised loads are loaded onto a truck or shipping container to regulate and prevent movement from those goods. They accomplish this through, among other things, load-bracing, filling voids, and absorbing impacts. Dunnage bags can be used in various forms of transportation, including trucks, trains, and cargo ships, helping to lessen damage during shipping.

Manufacturers, distributors and dealers, and shippers save time and money by using dunnage bags to transport cargo (such as consumer products, electronics, commodities, foods and beverages, and other items), which minimises losses from cargo damage in transit. Dunnage bags also serve a safety purpose by lessening the impact of load shifting because changing loads within containers is a prominent element in shipping accidents.

Dunnage bags are easy to use and require compressed air and inflate equipment with the attached valves. Dunnage bags are among the most cost-effective cargo protection and safety measures now available to shippers due to their simplicity of use, lightweight, and reusing ability.

Why use Dunnage Bags?

Dunnage bags offer cargo good support and stabilisation. They are made of inexpensive, solid, lightweight plastics like polyethene that are waterproof, recyclable, or reused, lowering transportation costs. Dunnage bags are available in various sizes, making them usable for different cargo types requiring protection. In addition to safeguarding shipment, dunnage bags lessen the potentially harmful consequences of load movement during transport.

Dunnage bags can be used between hazardous items and are mainly designed with lithium-ion battery packing because they fit between shipping containers like crates and cartons—these two components aid in establishing a secure atmosphere for individuals who deliver and transport the goods. Dunnage airbags secure cargo, safeguarding financial and commercial assets. They help to successfully move items at a lower cost by minimising loss from shipment damage.

Benefits of Dunnage Bags

Dunnage bags protect items during loading, transportation, and unloading, as well as during shipment and transit. They prevent objects from moving while being transported, whether they are sent by road, rail, or water. Dunnage airbags are significantly less expensive than specialised items and provide outstanding value. They offer an environmentally responsible alternative to other void filler choices because many of them are also fully recyclable. Dunnage bags shield products and primary or secondary packaging from moisture and contamination. Dunnage makes the delicate loading of cargo more straightforward and helps strengthen customer connections by preventing cargo damage.

Dunnage may fill any gaps in shipping containers and trucks, brace a cargo load, keep things in position, absorb impacts when they occur, and secure goods. Dunnage airbags offer a variety of benefits due to their adaptability, making them suited for over-the-road shipments and other forms of cargo transportation. The following are some of the main benefits:

  • Economical:

    When it comes to blocking and bracing, Dunnage airbags are far less expensive than other techniques like void fillers, lumber, or nails.

  • Optimal Strength:

    These bags can remarkably maintain loads and sustain enormous pressure and resistance to load movement.

  • Effective use of space:

    Dunnage bags also enable more efficient use of the container space.

Types of Dunnage Bags

The material to be shipped determines the sort of dunnage utilised; an example would be solid plastics used for expensive industrial goods. When transporting glass and other fragile items, bubble wrap is employed. Bulky products have traditionally been transported using dunnage made of wood. An affordable and environmentally beneficial dunnage option is the paper bag. Foam to cushion sharp objects, medical equipment, or electronic devices. Shipping construction materials and items that need to be protected from moisture are related to corrugated paper. Specific products demand custom dunnage solutions created using unique materials tailored to fit particular measurements. Common airbag types include the following:

Polywoven Air Bag

Polywoven airbags are mainly used for medium to heavy freight or products delivered via railroad since they include an airtight polyethene inner bladder and polypropylene woven outside layer. Strong and long-lasting polypropylene bags protect against harsh weather and chemical environments. They can easily be installed in difficult-to-reach spots, are moisture-resistant, and flexible enough to fit into strange gaps between cargo. They are also lighter than paper airbags, making it simple to load and unload them.

Paper Dunnage Bag

Paper airbags’ outside layer comprises kraft paper, and its inside layer is woven polypropylene. The most affordable option and best for dry cargo are paper dune bags. They are supplied in a variety of sizes which are economical and environmentally beneficial. Paper Airbags are quick and easy to load and unload, as well as to dispose of. Similar to poly woven airbags, they can swiftly fill a hole of unusual shape.

Woven Dunnage Bag

For shipments across rough or mountainous routes, woven dunnage bags are preferred. These bags can expand or contract following the altitude and conform to the contour of the bracing products. Being waterproof, they are frequently used for transporting perishable goods.

Is it possible for Dunnage Bags to Break?

Dunnage airbags are not flawless, despite their apparent close to perfection. They can become cold-burned, and the users need to be careful not to overfill the airbags during inflation since they might rupture. To establish the ideal pressure for your bag, look at the label next to the air valve on the bag. To protect the dunnage airbag from the sharp edges and corners found on pallets, wood boxes, and other packaging materials, it is best practice to place corrugated or another smooth surface on either side of the airbag in transit.


Dunnage Bags protect goods during shipment, making them an excellent load securement solution. Additionally, Dunnage Bags come in various types and can be customised to meet different product requirements.
