PP Woven Dunnage Bag for Container Void Fill – Polywoven Inflatable Dunnage Bag

PP Woven Dunnage Bags, also known as polywoven dunnage bags, are a cost-effective and reliable cargo protection solution for global intermodal transportation. Constructed with a durable woven polypropylene outer layer and a sealed PE inner air bladder, these bags are engineered to fill void spaces between pallets, cartons, drums and containers, effectively locking cargo in place to prevent sliding, tipping and impact damage during transit.

Compared with traditional wooden bracing, PP dunnage bags are lightweight, fast to install, recyclable and exempt from ISPM-15 regulations, eliminating fumigation costs and customs delays. Available in Level 1 to Level 5 strength grades, they are suitable for light cartons, heavy palletized goods, drums and fragile industrial cargo. Quick inflation and deflation enable repeated use, helping logistics operators reduce packaging waste and overall shipping costs. Trusted by freight forwarders, manufacturers and 3PL providers worldwide, our PP dunnage bags comply with AAR, CTU Code and international transport safety standards, making them the ideal void fill solution for sea freight, trucking and rail shipments.
