Specification FAQ
Questions that come up during specification review.
What is a spout top spout bottom FIBC bag?
A spout top spout bottom FIBC has a fabric tube at the top for guided, controlled filling and a fabric tube at the bottom for controlled discharge. Both spouts are tied closed when not in use. This configuration is used when both the fill and discharge processes require containment - common in chemical, food ingredient, and resin applications.
How does the bottom discharge spout work?
The bottom discharge spout is a fabric tube sewn into the base of the bag. It is tied closed during filling, transport, and storage. When the bag is ready to be emptied, the tie is released and the material flows out through the spout. Spout diameter and length are confirmed at specification review based on downstream equipment requirements.
When is a spout top spout bottom bag the better choice over an open top?
The spout top spout bottom format makes sense when controlled discharge is a process requirement - not just a preference. If your material is fine, sensitive to contamination, or part of a production workflow where discharge rate or containment matters, the spout-based configuration removes variables that an open-base approach would leave unresolved.
What is anti-sift construction and when is it needed?
Anti-sift construction refers to seam and stitch configurations that reduce or prevent fine material from escaping through the fabric weave or seam intersections. It is typically specified for very fine powders, chemical compounds, or materials with small particle sizes where leakage through standard construction is a concern. Available on request - confirmed at specification review.
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?
Use the RFQ form to provide company details, product interest, estimated quantity, bag dimensions, fill material, delivery destination, and timeline. That structure helps qualify requests and speeds up next-step conversations.
