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
Duffle Top / Flat Bottom FIBC Bags
Duffle top flat bottom bulk bags add a sewn fabric closure at the top of the standard open configuration - useful when covered transport, dust containment, or a cleaner fill environment is an operational requirement. The flat bottom provides the same stable pallet footprint as the open top format while the duffle gives you a tie-close option after filling.
Product Overview
About this bag configuration.
The duffle top / flat bottom FIBC is a woven polypropylene bulk bag that combines wide-access filling with a fabric skirt at the top that can be tied, folded, or cinched after filling. There is no spout - the fill area remains fully open and unrestricted, making it compatible with the same hopper, conveyor, or chute filling systems used for open top bags. The flat sewn bottom provides a stable, pallet-ready base. This format is commonly selected when buyers need some degree of post-fill closure without committing to a spout-top configuration. Liner options, print configurations, and loop style choices are available depending on project requirements.
Typical Applications
Common uses for this bag format.
- Food ingredients and dry blends - where covered transport or post-fill closure is an operational or customer requirement
- Plastic pellets and resin - pellet handling lines where the bag needs to be tied after filling to prevent spillage in transit
- Agricultural seed and feed inputs - programs requiring a simple covered format without the added cost of a spout configuration
- Industrial powders - where dust generation during transport is a concern and a loose-tie closure is sufficient
- Dry compounds and additives - operations where material integrity during transport benefits from a fabric barrier at the top

Why This Format
Why choose this bag style.
The duffle top is the practical next step from the open top format when the operation has a reason to close the bag after filling. It preserves the ease of fill access - no spout alignment required, no guided inlet to connect - while adding a closure option that works across a range of materials. If your filling system works best with an unobstructed top but your material, transport conditions, or customer requires some form of post-fill closure, the duffle top flat bottom resolves that without adding spout-based complexity to the specification. It is also a common choice in food ingredient and agricultural programs where a covered bag is expected but a full spout configuration is not required.

Product FAQ
Questions that come up during specification review.
What is a duffle top on an FIBC bag?
A duffle top is a fabric sleeve or skirt sewn around the top opening of the bulk bag body. After filling, the duffle can be tied, cinched, or folded closed to contain the material during transport or storage. It provides a closure option without restricting fill access the way a spout top does.
How does a duffle top bag differ from an open top bag?
Both formats allow unrestricted top filling. The duffle top adds a fabric closure that can be tied after filling. If your operation does not require any post-fill closure, the open top is simpler. If your material, transport conditions, or customer requirements call for a covered bag, the duffle top handles that without adding a spout.
What materials are suitable for duffle top flat bottom bags?
Common applications include food ingredients, plastic pellets, seeds, dry blended powders, and agricultural inputs where some degree of post-fill containment is useful. The duffle top is also used where dust generation during transport is a concern and a loose-tie closure is sufficient.
Can duffle top flat bottom bags be used for food ingredient applications?
Food-grade requirements are confirmed at project review. Liner options, body fabric, and closure method are all part of that discussion. XTRX does not make blanket food-grade claims - suitability depends on the specific material, handling environment, and buyer requirements.
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.
