Customer Pain Points & Challenges – We Understand Your Struggles
Are you facing these challenges?
High Sealing Breakage Rate: Poor sealing technology leads to air leakage, cargo damage, and customer claims.
Excessive Material Waste: Traditional machines waste film material during production, increasing costs.
High Energy Consumption: Conventional heat-sealing machines consume massive electricity, cutting into profit margins.
Coordinating Multiple Suppliers: Inner bag making, outer bag cutting, hole punching, assembly, sewing – 4-5 different suppliers to manage.
No Experience in Line Planning: Workshop layout, electrical design, raw material selection – no clue where to start.
Untrained Local Workers: Production stops once Chinese engineers leave. Long training time, high worker turnover.
Inconsistent Bag Quality: Weak seals, misaligned valves, poor assembly – leading to cargo damage and lost customers.
HAOSEN solves all of these with one integrated dunnage bag production line. See how below.

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-
