Industrial PP Woven Dunnage Air Bag PA‑PE Inner Film With ProAir Valve for Heavy Cargo Stabilization

Outer layer adopts wear‑resistant PP woven fabric with natural moisture‑proof property; inner is multi‑layer PA‑PE co‑extruded high‑barrier bladder for stable air‑holding. AAR certification grades range L0‑L5, corresponding to different working pressure and burst‑pressure parameters. Standard width covers 500‑1200 mm, length fully customizable. Two main‑valve selections: 10 mm traditional valve and upgraded ProAir 30 mm high‑flow valve, optional with cap, handle or cap‑handle assembly. OEM printing for logo, safety‑warning pictograms and batch traceability code is supported. Four‑step QC: raw‑material incoming inspection, full inner‑film online inspection, random sampling for finished goods, mandatory batch burst‑pressure test. Widely deployed for void‑gap filling inside sea‑containers, railway boxcars and heavy‑duty truck‑trailers for machinery, steel‑coil and palletized‑cargo securing.

PP woven dunnage air bag consists of polypropylene woven outer shell and PA‑PE composite inner bladder. PP woven material improves anti‑abrasion performance for repeated‑reuse scenarios, PA‑PE inner‑film prevents air‑leakage during long‑time transit. It obtains full‑range AAR L0‑L5 qualification to satisfy light‑load up to ultra‑heavy‑load‑bracing demand. Regular sizes are kept in stock, oversized special dimensions can be custom‑manufactured. ProAir series valve greatly accelerates inflation efficiency, while traditional 10 mm valve fits legacy inflator‑gun equipment. Surface printing includes brand graphic, caution‑mark and batch‑coding. QC procedure includes raw‑material check, in‑line inner‑film monitoring, 3‑5% finished‑goods random‑inspection and per‑lot burst‑pressure‑verification. Suitable for multi‑modal transport: ocean container, rail boxcar and long‑haul highway‑truck for pallet‑stacked‑goods stabilization.
