Dunnage Defined: Unlocking the Importance, Various Types, and Uses

In a world where the safe transport of goods is critical to business success, the term ‘dunnage‘ might not ring a bell for many, yet it plays an indispensable role in the journey of products from manufacturer to consumer.

Dunnage is the category of materials that go inside packaging to protect goods during shipment. It serves as a crucial element in ensuring product integrity, minimizing financial losses due to damaged items and optimizing transport efficiency.

This blog post will demystify the concept of dunnage, exploring its importance, the variety of materials available, and their specific applications across different industries.

Understanding the Concept of Dunnage

Dunnage, in the realm of shipping and packaging, refers to the materials used to protect goods during transport. 

It acts as a buffer, safeguarding products from damage by absorbing shock, bracing items within containers, and preventing movement that could lead to wear or breakage. The purpose of dunnage is to ensure that items arrive at their destination in the same condition they were in when they left the manufacturing facility or warehouse.

The selection of appropriate dunnage is crucial for the safety of cargo during transit. Different types of goods require specific dunnage solutions tailored to their size, weight, and fragility. 

The correct dunnage secures the cargo effectively and minimizes the risk of damage from vibrations, impacts, and other stresses experienced during shipment. This careful selection process is essential for maintaining product integrity from point A to point B, making dunnage an indispensable element in the logistics and transportation sectors.

Dunnage materials come in a variety of forms, each suited to different packaging needs and applications. 


Airbags, for instance, serve as inflatable dunnage, ideal for filling voids within shipping containers to prevent the movement of goods, thereby cushioning products against impacts. They are quick to deploy and highly adaptable to the shape and size of the cargo.


Foam dunnage provides a soft, protective layer around delicate items, offering superior protection against shocks and vibrations. This type of material is particularly beneficial for safeguarding electronics, glassware, and other fragile products during transport.


Wood, the most traditional form of dunnage, offers sturdy support for heavy-duty items and is frequently used in larger cargo shipments to separate and stabilize goods. It is also used for creating custom crates and pallets, providing a stable base for goods during transit. 


Plastic dunnage presents a versatile and reusable option, often used in the form of interlocking pieces or as a part of a modular system, fitting a wide array of products securely for transit. Plastic dunnage is also resistant to moisture, making it ideal for goods that require protection from humidity or water damage.


Paper dunnage, including crumpled paper, corrugated inserts, or paperboard, acts as an eco-friendly choice that provides lightweight cushioning and is easily recyclable. It can also be used as a filler material to absorb shock and prevent shifting of goods during transport.


Metal dunnage, though less common, is used for its durability and strength in securing heavy or high-value items, ensuring they remain immobile and protected during shipment. Metal dunnage is also resistant to fire and water damage, making it a preferred choice for high-value goods like machinery and equipment.

The graphic visually emphasizes the decision-making process involved in selecting appropriate dunnage materials to ensure protection and efficiency in packaging.

Selecting the most suitable dunnage for your shipping needs is crucial for ensuring the protection and integrity of your products. It begins with a thorough assessment of the item’s weight and the specific nature of the products being transported. Fragile items may require soft, cushioning materials like foam, while heavier goods might need the robust support of wooden or metal dunnage.

Environmental conditions during transit also play a significant role in determining the right dunnage. Factors such as humidity, temperature fluctuations, and the risk of water damage should be taken into account to prevent product degradation. Cost-effectiveness and reusability of dunnage materials are important considerations for businesses looking to optimize their packaging processes while minimizing waste.

Dunnage in Action: Real-World Applications

Dunnage plays an indispensable role across various industries by ensuring the safe transport of products.

Automotive Industry

In the automotive sector, specialized dunnage is used to protect parts and components from damage during shipping. This includes custom-fitted inserts for delicate items and sturdy supports for heavier parts, safeguarding against scratches, dents, and the rigors of transit.

Electronics Industry

The electronics industry relies on dunnage to prevent damage from physical shocks, vibrations, and electrostatic discharge. Foam padding and anti-static materials are commonly utilized to provide the necessary cushioning and protection for sensitive devices.

Food & Beverage Industry

Similarly, in the food and beverage domain, insulated dunnage is crucial for maintaining the integrity of temperature-sensitive goods, preventing spoilage over long distances. Insulated foam containers, liners, and ice packs are commonly used for perishable goods like produce, meat, and dairy products.

Pharmaceutical Industry

In the pharmaceutical industry, the use of hygienic and contamination-free dunnage is paramount to ensure products arrive in pristine condition, adhering to strict health and safety standards. These materials must be anti-static, hygienic, and chemically inert to avoid contamination and maintain the quality of medicines.

Retail Industry

In the retail sector, dunnage plays a vital role in protecting items during distribution and storage. For instance, clothing brands often use plastic or paper dunnage to bundle and secure merchandise together, preventing damage from shifting during transport. Similarly, food and beverage retailers utilize dunnage to secure and cushion fragile items like glass bottles and jars, guaranteeing they remain intact on store shelves.

Appliance Industry

In the appliance industry, dunnage is used to protect large, bulky items, such as refrigerators and washing machines, during shipment. These items require sturdy, shock-absorbing materials, such as foam or wood, to prevent damage during handling and transport.

The Environmental Impact of Dunnage

The shift towards sustainable, recyclable, and returnable dunnage materials has become a pivotal aspect of the packaging industry. Companies are increasingly recognizing the importance of minimizing environmental footprints and are thus opting for eco-friendly options. Biodegradable, compostable, and easily recyclable materials are now at the forefront of dunnage choices, reflecting a collective commitment to sustainability.

The role of biodegradable and compostable dunnage is growing, as these materials break down naturally, reducing landfill waste. Materials like biodegradable foam are a game-changer for businesses looking to reduce their environmental impact without compromising on product protection or shipping efficiency. Recyclable materials, such as corrugated cardboard and plastic, can serve multiple purposes during shipment – providing dunnage while also acting as packaging material.

Returnable dunnage, such as plastic or foam inserts, can be reused multiple times, reducing the need for new materials and minimizing waste. This approach is particularly beneficial for businesses with a high volume of shipments, as it not only reduces costs but also shows a commitment to environmental responsibility.
