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.
Quick Answer
The 30-second specification check.
- Use when Dry powders loaded from open hoppers and discharged into receiving hoppers
- 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.
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.

Specification 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.
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.
Do you supply customers across Canada?
XTRX is positioned as a Canada-wide supply partner for qualified buyers. Coverage messaging is national, with support for quote discussions involving Ontario, Quebec, Alberta, British Columbia, and other provinces.
