Dunnage Bags – Dual Bags

Dual bags are typically constructed from layered kraft paper or polyethylene with internal inflatable plastic chambers. X-Pak dual bags utilise Woven Polypropylene external layers paired with Co-Extruded Polyethylene internal coatings. These materials are selected for their robustness, flexibility, and puncture-resistance capabilities.

X-Pak's dual bag range features 8% recycled content. As Australia's only completely vertically integrated manufacturer, we continuously research ways to reduce virgin material usage in our dual bag production while maintaining premium quality standards.

Yes. Our dual bags support several reuse cycles when maintained in good working condition. The integrated valve mechanism allows straightforward deflation for repeated deployment. For 'closed loop' logistics operations, we strongly recommend dual bag reuse programs.

Dual bags can be deflated using two techniques:

Method 1: Inflate-X Pro 'Reverse Mode' - These systems provide the fastest deflation process for efficient dual bag emptying. Remove the air hose from its normal position and reconnect to the 'Air in' valve on the system's side.

Method 2: Metal Key System – For easy valve operation (protecting hands), insert the metal key into the dual bag valve and rotate to 'Open' position for air release (clockwise turn). Essential: Always rotate valve to 'Closed' after deflation and before re-inflation to ensure correct functionality.

Both methods enable effortless dual bag reuse while preserving valve integrity for ongoing applications.

Dunnage bag sizing depends on void spaces between your cargo and container sidewalls. Accurately measure these gaps and select bags capable of filling those spaces when correctly inflated. X-Pak offers complimentary site assessments to recommend optimal bag sizes for your specific shipping requirements.

No. Approximately 5 different valve types exist in the Australian dual bag market, each manufacturer-dependent. Some standard valves offer cross-compatibility. When in doubt, contact X-Pak to confirm compatibility between your bags or inflation equipment and existing setups.

While frequently used to fill rear-container spaces (between products and doors), this isn't recommended from a load-security perspective. The primary concern is bag ratings typically cannot withstand complete force from significant load shifts during transit. For large door spaces, we recommend container sheeting or certified tie-down systems like our Inflatable Door Tarp.

Dual bags are inflated using two main approaches. The conventional method employs compressed air systems. We provide pressure-gauged inflators that attach to air supplies and inflate dual bags to predetermined pressure levels. Alternatively, Portable Inflation or battery-powered systems (like our Inflate-X Pro) offer fast, convenient dual bag inflation.

Yes, subject to minimum order requirements and your specific needs. Situations involving uniquely shaped products or large void spaces may require specially designed dual bags. X-Pak's technical team can assist with any void-filling requirements you may have.

Yes, to a reasonable extent. We always recommend using protective sheeting such as corflute or cardboard barriers between dual bags and sharp edges wherever possible.
