Industrial powder often moves from an upstream hopper or filling machine to storage, mixing equipment or another production stage. The bag therefore functions as both a container and an intermediate process interface.
This Top-Fill Bottom-Discharge Baffle FIBC Bag allows material to enter through the top and leave through a dedicated bottom outlet.
It is intended for projects requiring equipment filling, closure, in-plant transfer and controlled discharge. Performance depends on compatibility with the actual equipment and powder.
The nominal filling spout measures Φ30 × 30 cm. It uses black 90 g/m² internally coated fabric and includes a 15 cm tie.
Before filling, the spout should be connected to a hopper outlet, screw conveyor or dosing nozzle. The connection must prevent powder from falling onto the outer top panel.
The diameter affects equipment compatibility, while the 30 cm length provides space for clamping and closure.
Graphite and other dusty powders may require extraction around the filling point. The tie closes the spout but does not replace leakage testing.
After loading, stop the material flow and allow suspended dust to settle before disconnecting the filling equipment. Fold and secure the filling spout according to the operating procedure.
The bag includes two Φ4 × 150 cm PP closure ropes and two Φ20 cm protective covers for the inlet and outlet areas.
A 25 × 30 cm self-sealing document pocket can hold the material name, batch number, net weight, filling date and transfer documents.
The document pocket is positioned near the top. Its orientation should remain visible when bags are placed on pallets.
The bottom outlet also has a nominal Φ30 × 30 cm configuration. It uses internally coated 90 g/m² fabric and includes a 15 cm tie.
Before opening, position the bag on a discharge frame with sufficient clearance and connect the spout to the downstream hopper or equipment.
Operators should not stand directly beneath a suspended bag while releasing the outlet. Opening sequence and operator position should be included in the site procedure.
Discharge performance also depends on flowability and compaction. Powders prone to bridging may require vibration or other assistance.

The top and bottom spouts both measure Φ30 × 30 cm, but this does not mean the filling and discharge conditions are identical.
The filling side involves feed rate, dust escape and bag clamping. The discharge side involves natural flow, bridging and downstream receiving capacity.
During high-rate filling, the inlet should remain fully open and displaced air must be managed to prevent sudden bag expansion.
If the downstream equipment receives material more slowly than the bag discharges it, the outlet opening may need to be controlled to prevent overflow or dust release.
This Top-Fill Bottom-Discharge Baffle FIBC Bag is suitable for collecting, temporarily holding, palletizing and discharging graphite powder, mineral powder, carbon-based powder, industrial fillers and other dry industrial materials. The Φ30 × 30 cm top inlet connects to filling equipment, while the bottom outlet transfers material to a mixer, hopper or subsequent process. Four internal baffles help control the filled profile, and four 5 × 100 cm loops support forklift-assisted handling. Sample validation should cover bulk density, flowability, equipment interfaces and discharge method.
The matching Φ30 × 30 cm dimensions provide defined filling and discharge structures, but the connected equipment can differ.
Upstream and downstream interfaces must still be checked separately.
Not by itself. Flow also depends on bulk density, flowability, compaction and how far the outlet is opened.
An actual powder discharge test is required.
No. It is a seam configuration intended to address potential powder paths around the seams.
Leakage performance also depends on needle holes, closures, particle size and testing.
It can hold batch labels, inspection status, filling dates and material-transfer information.
It supports traceability but does not change the bag’s physical performance.
The available specification does not establish this. No UN certification or electrostatic classification is provided.
Combustible dust and hazardous materials require separate standards and bag configurations.
Treat the filling and discharge spouts as two separate equipment interfaces. Verify their dimensions, operating clearance and dust-control requirements independently.
The bag should be approved only after a complete trial covering filling, closure, transfer, positioning and discharge.
