When shipping by rail, ride quality is completely unpredictable and uncontrollable. What is controllable is the method you choose to secure your load. Dunnagedirect.com offers a complete line of durable and reliable polywoven air bags that deliver uncompromised load securement and protection. We also have experienced sales representatives available to answer any of your questions or concerns about the best polywoven air bag to fit your specific shipping needs. We offer polywoven air bags designed for medium and heavy weight railcar loads, so finding the perfect one for your shipping application is easy. Our polywoven air bags are also much easier to handle than alternative paper bags because they are 60% lighter and their single-ply construction allows for a greater pack-out. The polywoven air bags offered by Dunnagedirect.com are resistant to harsh chemical environments and are also weatherproof resistant so they are great for open railcar shipments. They also have high burst strength to withstand the harshest shipping conditions and are great for both lateral and longitudinal railcar bracing.
