Dunnage Bag Articles

The 4 key dunnage bag standards: AAR load levels with working pressures, SGS/TUV material testing, MSDS chemical safety and ISO 9001 quality management.

The dunnage bag valve: old-style vs fast valve, the two-way auto-lock, valve materials and choosing a compatible inflation gun with a gauge.

What woven PP fabric is: tape extrusion, cross weaving and coating, why it resists tearing, and its use in jumbo bags and high-AAR dunnage bag shells.

Use a dunnage bag in 5 steps: assess the void, protect sharp edges, position, inflate to working pressure, and check/deflate. Plus in-box air bags.

Key dunnage bag metrics: AAR load levels, standard vs non-standard voids, max void and bridging, and static vs dynamic compression explained.

What a dunnage bag is and how it works: static vs dynamic compression, void sizing, 3-layer construction (kraft, woven PP, PA/PE) and AAR load levels.

What kraft liner is: the load-bearing facing of corrugated board, virgin vs recycled grades, grammage, and its role in ECT/BCT box strength and dunnage bags.

What the SGS standard is and why it matters in logistics: trade-passport role, dunnage-bag testing (tensile, drop, vibration, burst) and ROHS compliance.

Dunnage bag structure: the 3 layers, kraft vs woven PP outer shells, AAR levels 1-5, working pressure and max void. A full classification guide from ICD.
