Application Fields – What Can Dunnage Air Bags Do?
Dunnage Air Bags – Essential Cargo Protection for Global Logistics
Dunnage air bags (also known as inflatable dunnage bags, cargo air bags, or container air bags) are inflatable bags used to fill gaps between cargo, securing their positions, supporting weight due to shaking, absorbing vibrations, and protecting goods during transportation – preventing movement, mutual collision, and serving as buffer and anti-collapse measures. HAOSEN's dunnage bag production line enables you to manufacture high-quality bags for a wide range of logistics applications:
| Industry | Application | Typical Scenarios |
| Container Shipping | Filling gaps between cargo inside sea containers | International freight, FCL & LCL shipments |
| Truck & Trailer Transport | Securing palletized and full-board cargo | Long-haul trucking, less-than-truckload (LTL) |
| Rail Freight | Bracing cargo against railcar walls | Intermodal transport, cross-border rail |
| Industrial Goods | Protecting heavy machinery and equipment | Manufacturing logistics, project cargo |
| E-commerce & Consumer Goods | Filling voids in mixed cargo shipments | Distribution centers, parcel logistics |
| Electronics & High-Value Goods | Shock absorption and vibration protection | Sensitive equipment, fragile items |
Key Global Data:
·Dunnage air bags are widely used across various transportation modes including sea containers, maritime shipping, trucks, and rail freight.
·Single bag pressure resistance: 0.5–1.0 kg/cm², safe pressure rating: >1.0 kg/cm².
·Inflation thickness reaches 300–550mm, effectively filling gaps between cargo.
·Reusable and more environmentally friendly than traditional void-fill materials such as foam plastics.
From sea containers to trucks, from railcars to warehouse distribution – dunnage air bags are the backbone of modern cargo protection. HAOSEN's turnkey production line empowers you to capture this growing market with reliable, high-

Success Story – Real Project, Real Results
Case: Full Automated Dunnage Bag Production Line – 600 Bags/Hour
Customer Need: A European logistics packaging company needed a complete automated dunnage bag production line to meet growing demand from container shipping customers.
Challenge: The customer required high production speed (600+ bags/hour), zero leakage guarantee, and support for multiple bag sizes (900×1800mm, 1200×2400mm). Local technical resources were limited.
HAOSEN Solution: Provided a full turnkey automated line including: HSWLD-1300A intelligent inner bag making machine (UPT sealing technology, 0% breakage) + automatic inner-outer bag assembling machine (AI vision inspection, 6-12 bags/min) + automatic cutting machine + double-side automatic sewing machine + auxiliary equipment (air compressor, water chiller). Full workshop layout design, on-site installation, and 4-week engineer training.
Result: Line commissioned within 120 days, running at full capacity. Zero sealing breakage rate achieved. Local team fully independent after 4 weeks. Annual output exceeds 2 million dunnage bags.
Customer Says:
"HAOSEN's UPT sealing technology is a game-changer. Zero leakage means zero cargo damage claims – our customers are thrilled." —— Operations Director, European Logistics Packaging Company
