Packaging hard-to-handle materials in valve bags
If your material is very fine, lightweight, nonfree-flowing, or otherwise hard to handle, you should know there are ways to economically package the material in valve bags. After discussing requirements for economical bagging and listing some hard-to-handle materials, this article covers various methods for producing stackable valve bags of accurate weight and explains how to choose a valve sealer. Related information provides more detail about recycling valve bags and types of valve sealers.
Bagging operations are faced with achieving higher production rates, ensuring high bag-weight accuracy, maintaining a clean bag appearance, and keeping a clean environment for workers. Environmental concerns also demand that bag materials be recycled to reduce solid wastes. [Editor's note: For more information, see the sidebar, "Helping to meet environmental demands: Recycling valve bags."] To achieve these goals economically can be a challenge.
