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.

Open top discharge spout bottom FIBC bag for unrestricted filling and controlled emptying.

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
