FIBC Bulk Bags
Spout Top / Flat Bottom FIBC Bags
Spout top flat bottom FIBC bags give buyers a guided fill point at the top while keeping the simplest possible pallet base at the bottom. This format is used when the loading side needs better containment or better alignment with filling equipment, but the bag will still be discharged by tipping, cutting, or one-time release rather than through a sewn bottom spout.
Product Overview
About this bag configuration.
The spout top / flat bottom configuration combines a top fill spout with a flat sewn base. The top spout supports cleaner, more controlled filling into the bag body, while the flat bottom keeps the bag stable on a pallet and easy to handle in storage and transport. This format is a practical choice for powders, ingredients, resins, and industrial materials that benefit from guided filling but do not require a controlled discharge outlet.
Typical Applications
Common uses for this bag format.
- Food ingredients loaded through guided filling equipment but discharged by cut-open emptying
- Plastic pellets and specialty resin where top containment matters more than bottom metered flow
- Fine powders that benefit from controlled filling into the bag body
- Industrial additives and dry compounds with a cleaner top-loading requirement
- Chemical powders where loading containment matters but a bottom spout is not required
