Spout Top / Spout Bottom FIBC Bags
A controlled-fill and controlled-discharge bulk bag format for operations where material containment and measured emptying are process requirements.
FIBC Bulk Bags
Duffle Top / Discharge Spout Bottom FIBC Bags
Duffle top discharge spout bottom bulk bags combine the fill flexibility of a wide open top with the discharge control of a fabric bottom spout. The duffle top accommodates unrestricted filling from hoppers, conveyors, or manual loading systems. The discharge spout controls how and where the material exits. If your fill process is straightforward but your discharge process is not, this configuration handles both sides of that problem.
Quick Answer
The 30-second specification check.
- Use when operations where powder is loaded freely from above but must discharge in a controlled stream
- Safe working load 500 kg to 2,000 kg standard
- Fabric Woven polypropylene - coated or uncoated
- Sizes 35 x 35 x 40 in to 42 x 42 x 72 in common range
- Test standard ISO 21898 (COC included)
What This Configuration Is
About this bag configuration.
The duffle top / discharge spout bottom FIBC is a hybrid woven polypropylene bulk bag that pairs a broad, closeable top opening with a bottom discharge spout for controlled emptying. The duffle top allows flexible filling from wide-mouth hoppers, conveyors, or manual loading without the alignment requirements of a top spout. After filling, the duffle is tied or cinched closed. The bottom discharge spout provides a controlled, directed outlet that supports cleaner emptying into downstream equipment. This format is commonly selected when the fill process is unconstrained but the discharge process requires containment or equipment alignment. Liner options, coating choices, loop styles, and print configurations are available on request.

Industries & Applications
Where this bag fits.
- Dry blended powders - operations where powder is loaded freely from above but must discharge in a controlled stream
- Pellets and granules - plastic pellets, feed pellets, or granulated compounds where a directed outlet matters at the unloading station
- Agricultural inputs - seed, feed ingredients, or crop inputs loaded from bulk hoppers and discharged into specific equipment or containers
- Industrial additives and compounds - materials handled in processing environments where fill is batch-based but discharge is equipment-integrated
- Recycled and regrind material - where loading is uncontrolled but the receiving system at the other end requires a directed inlet

Specification FAQ
Questions that come up during specification review.
Why would an operation need both a duffle top and a discharge spout bottom?
This configuration is for operations where the fill process is flexible and does not require a guided spout - but the discharge process does. The duffle top allows wide-access filling from hoppers, conveyors, or manual loading. The discharge spout gives the unloading side the control it needs for downstream equipment alignment or material containment during emptying.
How is this different from a spout top spout bottom bag?
A spout top spout bottom bag uses a guided spout for filling as well as discharge. The duffle top discharge spout format uses a wide open top for filling - which is easier to load from but not guided - and a spout for discharge only. If your fill process does not require a guided inlet but your discharge process does, the duffle top discharge spout bottom is the more practical choice.
What materials work well in duffle top discharge spout bags?
This format works well for dry granular materials, pellets, agricultural inputs, and industrial powders where loading flexibility is valued and controlled emptying is needed. It is commonly used in agriculture, plastics processing, and industrial compounding environments where the fill station and discharge station have different equipment constraints.
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.
How do I request a quote?
Use the RFQ form to provide company details, product interest, estimated quantity, bag dimensions, fill material, delivery destination, and timeline. That structure helps qualify requests and speeds up next-step conversations.
