What This Configuration Is
About this bag configuration.
The skirt top / flat bottom configuration uses a skirted top closure above the bag body and a flat sewn base. It preserves pallet stability and straightforward handling while providing a covered top format for transport, storage, or customer presentation. This makes it useful for agriculture, recycling, landscaping, and general industrial materials where top protection is helpful but a top spout is unnecessary.

Specification FAQ
Questions that come up during specification review.
Why choose a skirt top flat bottom FIBC bag?
Skirt top flat bottom bags are used when the buyer wants a covered-top format for storage, transport, or presentation, but does not need the guided filling hardware of a spout top.
What is the difference between a skirt top and a duffle top?
Both provide top coverage, but the duffle top is typically more fill-friendly and tie-oriented, while the skirt top is often selected for simpler covered-top presentation and protection. The right choice depends on fill method and closure preference.
