FIBC Bulk Bags

Skirt Top / Discharge Spout Bottom FIBC Bags

Skirt top discharge spout bottom FIBC bags are used when the bag should stay covered at the top but still empty through a controlled bottom outlet. This configuration supports programs where transport or storage benefits from a closed-top look, while the receiving end still needs a fabric discharge spout for cleaner unloading.

What This Configuration Is

About this bag configuration.

This format combines a skirted top closure with a bottom discharge spout. The covered top supports transport and storage requirements, while the spout bottom supports cleaner, directed material release into receiving bins or downstream equipment. It is a practical hybrid for agricultural inputs, dry blends, powders, and other bulk materials where top presentation and bottom process control both matter.

Specification FAQ

Questions that come up during specification review.

When should I use a skirt top discharge spout bottom bag?

Choose this format when top protection matters during storage or transport and the receiving side still needs a controlled bottom discharge into equipment or containers.

How does skirt top discharge spout bottom differ from duffle top discharge spout bottom?

Both provide controlled bottom discharge. The main difference is the top profile: the skirt top gives a more covered-top presentation, while the duffle top is usually preferred when the operation needs a wider and more fill-friendly closure style.
