Understanding Void Fillers and Dunnage Air Bags
Shipping experts rely on strategic packaging techniques to maximize cargo protection throughout the supply chain. Proper packaging systems not only safeguard products but also optimize transportation efficiency and reduce costs.
What are void fillers?
Void fillers serve as protective materials placed inside shipping containers to fill empty spaces between products and packaging walls. Unlike protective packaging that wraps directly around items, void fill specifically addresses the gaps that allow products to shift during transport. These materials—typically made from paper, foam, plastic, or molded fiber—prevent movement rather than primarily cushioning impacts.
The principle behind void fill is straightforward: when products remain stationary during transit, they're less likely to collide with each other or container walls. Moreover, void fill enhances the unboxing experience for customers by ensuring products arrive intact and professionally presented.
How dunnage air bags work in shipping
Dunnage air bags represent one of the most effective void fill solutions available. These inflatable pouches, constructed from multiple layers of paper or poly materials with internal polyethylene bladders, fill spaces between cargo items to prevent shifting. When properly positioned and inflated, these bags exert pressure against cargo loads, effectively locking pallets in place against trailer walls.
The versatility of dunnage air bags makes them especially valuable—they limit movement both horizontally and vertically while simultaneously absorbing vibrations during transport. Furthermore, their implementation can dramatically improve shipping outcomes: installing dunnage air bags reduces average unloading time by up to 66% and helps decrease damage claims by approximately 80%.

Why inflators matter for air dunnage bags
Inflators play a crucial role in maximizing the effectiveness of dunnage air bags. These specialized devices pump air into the bags, allowing precise pressure control through adjustable settings that accommodate different bag sizes and materials. The inflator connects directly to the dunnage bag valve, expanding it to fill gaps between cargo items.
Quality inflators significantly enhance operational efficiency. Notably, modern inflators perform up to 66% faster than traditional systems, consequently reducing labor costs and shipping delays. A proper inflator setup requires three key components: compressed air from a compressor, an inflator tool, and an air gauge to monitor pressure levels.
For high-volume shipping operations, manual inflation methods prove impractical. Investing in professional-grade inflators represents a preventive measure that ultimately saves money through reduced damage claims while ensuring dunnage bags meet necessary safety standards.

Types of Void Fill Solutions for Cargo Safety
The shipping industry offers several specialized void fill solutions, each designed to address specific cargo securement challenges. Let's explore the most effective options available for freight protection. You can read our recent article about Void Fillers: The Ultimate Guide to Protective Packaging
Drop-down void fillers
These diamond-shaped corrugated fillers provide lateral protection for both center and sidewall voids. Their innovative design allows them to be shipped flat and expanded when needed, fitting 20-50 times more fillers per truckload compared to traditional panels. Drop-down void fillers are remarkably efficient at providing unit stability during transit. Their accordion-style design makes them not only easy to store but also simple to install—significantly faster than traditional airbags.
Dual drop-down filters
Particularly valuable for proper weight distribution, dual drop void fillers are specifically engineered to brace center-loaded units for correct axle weights. The side filler extends downward on one side of the unit, restricting side-to-side movement. These corrugated solutions secure single pallet units while helping maintain proper axle weight distribution. Straightaway noticeable is their customizability—tailored to specific drop length and void width requirements, they ship folded flat for convenient storage.
Inflatable dunnage bags
Perhaps the most versatile void fill option, inflatable dunnage bags offer superior load stabilization across multiple transportation methods. Constructed from either paper layers (2-8 plies) with polyethylene bladders or woven polypropylene with plastic liners, these bags expand to fill spaces between cargo. Premium options like D-Connect Dunnage Bags inflate in merely 17.5 seconds—20% faster than competing products. Given that they're 100% recyclable, these bags effectively fill voids while absorbing vibrations that could otherwise damage products.
