New Reusable Bulk Bags for Helicopter Transport of Sand and Gravel

In the past, helicopters within the Forest Service have used flexible intermediate bulk containers (FIBCs) to transport dry-flow materials, such as sand or gravel. Because these bags could be used only once, they were not cost effective and their popularity waned.

The tech tip, Reusable Flexible Intermediate Bulk Containers (0557–1304P–SDTDC), describes reusable bulk bags that are now available. The new design is constructed from a heavier polypropylene fabric with sturdier weaving that has been treated with ultraviolet light inhibitors to prevent sun damage and chemical degradation.

Reusable bags cost two to three times more than nonreusable ones. However, with proper inspection and maintenance, a reusable bulk bag can last until a project is completed.

The tech tip includes a list of bag manufacturers, ordering information, and maintenance instructions.

For more details on reusable flexible intermediate bulk containers, contact Ron Tam, project leader (phone: 909–599–1267, ext. 274; e-mail: rontam@fs.fed.us).
