Every day, Unit Load Devices (ULDs) are hard at work, enabling the global supply chain to operate smoothly. From the smartphones in our hands to life-saving medical supplies, ULDs ensure that goods are transported efficiently, reliably, and safely across the world.
Although air freight accounts for only about 1% of global trade volume, it represents an estimated 35% of its value. Air freight is extremely important for transporting high-value and time-sensitive goods, and ULDs – like lower deck containers, main deck containers, pallets & extenders, and fire-resistant containers – are at the heart of these operations.
Meeting Modern Challenges with Innovation
Still, the air cargo industry faces growing challenges, from fluctuating cargo volumes to increasing pressure toward greater sustainability. Seasonal imbalances in passenger and cargo traffic often leave airlines with an oversupply of empty containers at some locations, wasting valuable cargo space and adding unnecessary costs.
Collapsible containers offer a practical solution to these inefficiencies. AviusULD’s S-series collapsible AKEs, introduced in 2024, allow multiple empty containers to be stacked for transport on return flights, freeing up space for revenue-generating cargo. These lightweight and user-friendly containers reduce CO2 emissions, require less ground equipment for handling, and simplify the storage process. By addressing both operational inefficiencies and environmental concerns, collapsible containers represent a major step forward for airlines striving to reduce waste and meet sustainability goals.
These types of sustainability solutions remain central to the air cargo industry’s future. Modern ULDs, designed for durability and reduced weight, help lower fuel consumption and emissions during transport. Circular production processes, such as recycling aluminum for new containers, further minimize waste while maximizing efficiency. Together, these innovations demonstrate how ULDs are evolving to meet the dual demands of efficiency and environmental responsibility.
Enhancing Safety in the Sky
Safety remains a top priority for the air cargo industry, particularly as the prevalence of lithium-ion batteries in consumer electronics continues to grow. In the United States, for example, FAA data shows that lithium battery fires on flights have risen 388% since 2015, now occurring nearly twice a week.
To mitigate these risks, fire-resistant containers (FRCs) are becoming essential. These specialized ULDs provide critical protection by containing fires long enough for crews to respond safely. As safety concerns evolve, FRCs are poised to play an increasingly vital role in ensuring the secure transport of goods.
Pushing the Industry Forward
As global trade evolves, so too do the demands on air cargo. Smart ULD technology is transforming how airlines manage their assets by enabling real-time tracking, environmental monitoring, and better decision-making. These advancements, combined with ongoing innovations in container design and materials, are positioning ULDs to meet the challenges of tomorrow.
From transporting fresh produce to delivering critical medical supplies, ULDs remain indispensable to global supply chain operations. As the aviation industry continues to innovate, these essential tools will ensure that goods are moved sustainably, safely, and efficiently – keeping the world connected every step of the way.
