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 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
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.

Why This Format
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.

These formats are worth reviewing if your application has requirements this configuration does not fully address.
A straightforward 1-ton bulk bag for dry flowable materials that need efficient filling and stable pallet handling.
A hybrid bulk bag combining wide-access top filling with a controlled bottom discharge spout - for operations where fill flexibility and discharge precision are both required.
Maximum top fill access with built-in liner compatibility - for materials that need a barrier layer and a wide-mouth loading format.
Product FAQ
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.
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.
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.
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.
Liner options can be discussed during the RFQ process when the application, material characteristics, and handling requirements call for additional containment or barrier support.
