• 【Professional Grade Securement & 2.9 PSI High Pressure】Engineered for superior load stabilization, our dunnage bags support a maximum operating pressure of 2.9 PSI (20 kPa). This high-pressure capacity provides a firmer, more rigid cushion than standard bags, effectively locking cargo in place and preventing any shifting during heavy-duty truck or intermodal transit.
• 【Jumbo 30-Inch Expansion for Wide Voids】Master the widest gaps in your container. With an extraordinary 30-inch (76cm) inflation depth, these extra-large 48" x 84" bags are specifically designed to fill massive "dead zones" between oversized pallets, machinery, and container walls that standard bags simply cannot reach.
• 【Premium Woven Polypropylene (WPP) Construction】Crafted from high-tensile Woven Polypropylene, our bags offer exceptional puncture and tear resistance. The multi-layer design with a co-extruded PE inner film ensures maximum air retention and durability, outperforming traditional paper bags in rugged industrial environments.
• 【Versatile Protection: Pallets, Crates & Barrels】The ultimate solution for diverse cargo shapes. Our WPP bags provide a uniform brace for corrugated boxes, wooden crates, and even rounded steel barrels. By filling the awkward gaps between pallets, they eliminate the "domino effect," ensuring fragile goods arrive without crushed edges.
• 【Rapid Spring-Loaded Valve & Sustainability】Fitted with a professional spring-loaded rapid-fill valve, our bags allow for fast inflation and controlled deflation. Made from 100% recyclable materials and moisture-proof fabric, these bags are designed for multiple reuses, offering a cost-effective and eco-friendly alternative for your logistics.
