Kraft Paper Dunnage Bag – Inflatable Container Void Fill Bag with PE Inner Bladder

Kraft Paper Dunnage Bags—also called paper inflatable dunnage bags or kraft void-fill air bags—are a cost-effective, recyclable cargo-securing solution for dry and light-to-medium industrial loads. Each bag pairs a multi-ply extensible kraft paper outer shell​ (typically 2, 4, 6 or 8 plies, optionally PP/PE laminated for moisture resistance) with a high-barrier PE or PA/PE inner bladder​ that holds compressed air without leakage. When inflated via a standard valve and air compressor, the bag expands to fill the void between pallets, cartons or cargo blocks and the container wall, applying even bracing pressure that stops sliding, tipping and collision during sea, road and rail transit.

Compared with wooden bracing, paper dunnage bags install in seconds, leave no debris, and are ISPM-15 exempt. The kraft surface delivers a high friction coefficient against cartons and pallets, helping “lock the load” better than slick plastic alternatives. Rated AAR Level 1 to Level 3, they cover most truck, intermodal and ocean shipments of bottled beverages, consumer goods, bagged products and standard palletized freight. After unloading, bags deflate quickly and the kraft/PE materials are 100% recyclable, aligning with EU/US green-packaging expectations. Available in standard sizes (e.g., 500×1000 mm to 1000×2000 mm) and custom dimensions, our paper dunnage bags give logistics teams a lightweight, compliant and budget-smart alternative to polywoven bags for non-humid, general cargo lanes.

• High-Friction Kraft Grip:​ Rougher paper face bites into cartons and pallets better than PP woven fabric, locking loads tighter against container sidewalls.
• Economical Void Fill:​ Lower unit cost than polywoven bags—ideal for cost-sensitive FMCG, beverage and carton export lanes.
• Recyclable & Green-Compliant:​ Kraft is renewable and the whole bag enters standard paper/PE recycling streams; satisfies EU/retailer sustainability audits.
• Fast 30-Second Install:​ Drop in void, connect inflater, hit target PSI, walk away—no carpentry, no nails, no clean-up versus timber bracing.
• AAR Level 1–3 Certified:​ Matches North American and intermodal rail/truck standards for light-to-medium palletized and cartonized cargo.
• Custom Ply & Size:​ Scale ply count and dimensions to your exact void width and lane severity—no over-spec, no waste
