Import Dunnage Air Bag For Container — Buy in wholesale FOB from Supplier in China

The DUNNAGE AIR BAG FOR CONTAINER from Tianjin Zerpo Supply Co., Ltd. is a multi-layered inflation system designed to immobilize cargo within shipping containers. The outer layer is constructed from polypropylene (PP) fabric, providing high resistance to compression and abrasion, while the inner layer consists of nine co-extruded polyamide (PA) films to ensure air-tightness and elasticity. The integrated one-way valve prevents air leakage after inflation, maintaining pressure throughout transit. This product is engineered specifically for containerized freight where vibration, shifting, and impact are common risks.

These air bags are rated to withstand over 9.5 tons of compressive force, as verified by the China Packaging Research & Test Center. The material composition meets RoHS requirements, confirmed by SGS testing, and production undergoes 12 dedicated quality inspections. Unlike generic alternatives, this product is manufactured with consistent film thickness across layers, reducing the risk of puncture or slow deflation. Typical industry standards for such bags include a burst pressure of 120 kPa and a service temperature range of -20°C to 70°C, which this product reliably meets.

Buyers commonly use these bags to secure electronics, glass ceramics, machinery, furniture, and chemical drums during ocean freight. They are preferred by logistics providers seeking to reduce damage claims and loading time, as inflation requires no tools and can be completed in under 30 seconds per bag. Packaging is customizable per order, with options for bulk rolls or pre-cut sizes. Trade terms are typically FOB Tianjin, with lead times of 10 to 15 days after deposit confirmation, though exact terms require direct supplier verification.
