While dunnage isn’t a typical vocabulary word of the average consumer, it’s a commonplace term for shippers. Used to describe packaging components like bubble wrap, kraft paper, crinkle paper, plastic bracing, fillers, planks, blocks, and boards, dunnage helps secure and support packages throughout the shipping and handling process. 

If you’ve ever picked and packed an order, you probably used dunnage to help protect the products in some way. The more fragile an item, the more dunnage it needs. For example, if you shipped a glass vase, you probably used bubble wrap to fill in the gaps in the box so the case wouldn’t shift around. Alternatively, if you shipped a pillow, you don’t need any dunnage given the low risk of damage while in transit.

What is dunnage?

Dunnage is the durable padding material used to protect goods during shipping. Dunnage can be anything from bubble wrap and packing peanuts, to industrial solid plastics that provide cushioning so items stay put.

Of course, dunnage will do its job best when accompanied by the appropriate box or poly bag. Shippers shouldn’t place a small item in a large box and fill it with dunnage, nor should they put a fragile item in a bubble mailer and call it a day.

Why shippers use dunnage

During transit, your packages may go through tough environmental conditions while in sorting facilities, trucks, ships and other vehicles. Dunnage is useful because it prevents items from moving and helps to absorb shock. Here are the three main benefits of using dunnage:

1. Damage protection

Dunnage protects packages when they are sliding across a truck, ship, or train. Proper dunnage can be incredibly cheap, but it protects valuable, fragile, and loose items. 

2. Moisture protection

Depending on where products are being shipped, moisture can harm the products. With the right dunnage, you can protect valuable equipment like electronics from moisture when shipping. 

3. Shock absorption

Products being shipped can slide around, drop, get squished, or be subject to collision, which can lead to shock and vibration. Dunnage is always put in place to act as a shock absorber to prevent damage. 

The 9 types of dunnage

There are many types of dunnage materials available. Depending on the type of products you sell, you can use a lightweight material like bubble wrap to protect smaller items, while using steel to protect expensive and heavy items. Here are common dunnage materials used for shipping packages:

1. Solid plastics

This kind of dunnage is used mostly in industrial, high-value shipping. Solid plastics are more expensive than other dunnage types but are worth the cost for high-value products that need protection.

2. Bubble wrap

Bubble wrap is one of the most common ways of shipping glass and other fragile products. It can be reused again and again as long as the bubbles don’t pop.

3. Wood

Wood can be used to create barriers between items, usually used for strong and heavy goods. 

4. Air pillows

Air pillows can be deployed inside packages in order to keep items from sliding. These are often used as a gap filler to fill in missing space.

5. Kraft paper

Kraft paper is recycled paper usually crinkled and stuffed in a package. It’s one of the most common dunnage types because it’s:

  • Cheap
  • Eco-friendly
  • Reusable
  • Highly effective 

6. Foam

Foam is often used to pad electronics, medical equipment, sensitive items, and fragile or sharp pieces. If you’ve purchased a TV before, you’ve probably taken it out of the box with foam dunnage on the side. 

7. Steel

Steel is one of the most expensive dunnage options which is typically used for high-value shipping. If your products are heavy, steel is a good dunnage option because it can prevent heavier products from damaging lighter products.

8. Corrugated paper

Corrugated paper is another popular dunnage choice. Its high-tech construction ensures the material can carry a wide range of weights, protects against moisture, and provides sustainable packaging options.

9. Custom dunnage solutions

Custom dunnage is needed sometimes when you have fragile materials that have very specific dimensions. You can work with dunnage providers to help you design the dunnage needed to protect your products. 


Dunnage is important not only for big freight shippers, but also for ecommerce shops wrapping their packaging in dunnage such as bubble wrap, crinkle paper, air pillows, recycled paper (aka kraft paper).

Depending on the types of products you’re shipping, the varied array of dunnage options can help you ship products so they reach customers without getting damaged. With the right dunnage, you can also prevent customers returns because no one wants a damaged product.

When looking into dunnage options, take into consideration the types of products you have, how they’re shipped, weights and packing options to find the right dunnage for you. If you’re outsourcing logistics to a 3PL, make sure to ask about their dunnage options and how they keep your products safe while in transit.
