Specification 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.

How do I request a quote?
