Open Top / Flat Bottom FIBC Bags
A straightforward 1-ton bulk bag for dry flowable materials that need efficient filling and stable pallet handling.
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

Why This Format
Why choose this bag style.
Choose open top / discharge spout bottom when the fill side does not justify a top spout, but the unload side absolutely benefits from controlled discharge. It keeps the specification simple at fill and more process-friendly at emptying, which makes it useful in quarry, mineral, dry blend, and construction-material programs.

Product FAQ
Questions that come up during specification review.
When is an open top discharge spout bottom bag the right choice?
This format makes sense when the bag should fill freely from above but still discharge through a controlled outlet into receiving equipment. It is common in minerals, dry blends, and construction-material programs.
How is open top discharge spout bottom different from open top flat bottom?
Both use unrestricted top filling. The difference is on the unloading side: open top flat bottom bags are usually tipped or cut open, while open top discharge spout bottom bags empty through a sewn outlet for cleaner, more directed discharge.
Do you offer liner options?
Liner options can be discussed during the RFQ process when the application, material characteristics, and handling requirements call for additional containment or barrier support.
Can XTRX support custom bag sizing and specifications?
Yes. XTRX is positioned to support project-specific requests for dimensions, loop styles, coating, liner needs, print requirements, and target load parameters. Final specifications should be confirmed through the quote process.
