When it comes to high-stakes shipping, "good enough" is not an option. The Rockcub Jumbo Dunnage Air Bag is engineered to bridge the critical gap between cargo safety and efficiency. Featuring a reinforced Woven Polypropylene (WPP) exterior and a high-performance 2.9 PSI pressure rating, these bags provide a rock-solid brace for your heaviest loads in 53ft trailers, railcars, and ocean containers.
Why 2.9 PSI and 30" Expansion Matter:
In the demanding world of logistics, a loose load is a damaged load. Our bags provide a more rigid and stable cushion by allowing higher internal pressure (2.9 PSI / 20 kPa). The unique 30-inch expansion capability means you can secure wide voids between pallets, machinery, or crates that would otherwise require multiple smaller bags or expensive timber bracing.
Engineered for Diverse Shipping Scenarios:
Standard & Oversized Pallets: Effectively bridges the gaps between pallet rows to prevent lateral leaning and longitudinal movement.
Industrial Crates & Machinery: Provides a heavy-duty bulkhead to secure large wooden crates and heavy equipment against container walls.
Barrels & Drums: The massive expansion is perfect for the large, irregular voids created by cylindrical loads, ensuring they remain upright and locked.
Weatherproof & Rugged: Unlike traditional paper bags, our waterproof WPP material remains 100% effective in humid, rainy, or cold-chain environments.
