FIBC Bulk Bags
Open Top / Discharge Spout Bottom FIBC Bags
Open top discharge spout bottom FIBC bags are used when the bag needs to fill freely from above but still discharge through a controlled outlet at the destination. This format is common where the filling operation is simple, but the receiving hopper, process line, or customer discharge setup needs a bottom spout rather than a cut-open bag.
Product Overview
About this bag configuration.
This configuration combines a full open top with a bottom discharge spout. The open top makes loading easy from hoppers, conveyors, or manual fill stations. The discharge spout gives the unloading side a cleaner, directed outlet for transfer into downstream equipment or receiving bins. It is a practical hybrid for minerals, construction materials, powders, and dry bulk materials where fill access is unrestricted but discharge needs control.
Typical Applications
Common uses for this bag format.
- Dry powders loaded from open hoppers and discharged into receiving hoppers
- Construction materials that fill easily but need controlled bottom unloading
- Mineral fillers and aggregates transferred into downstream process equipment
- Dry industrial blends that need a simple top fill point and clean bottom outlet
- Bulk materials distributed to customers who unload into process equipment
