Internal baffles restrict outward expansion, but they also change the flow path inside the bag. Without suitable openings, powder may remain concentrated in the centre instead of reaching the corners.
This Four-Baffle FIBC Bag contains four 35 × 44 cm internal panels. Each panel has two evenly distributed 10 × 20 cm oval openings, providing eight powder-flow openings in total.
The purpose of the dual-opening design is to provide access to the corner areas while retaining the connecting sections of each baffle.
At the beginning of filling, powder enters the central area and moves downward and outward under gravity and material pressure.
When the material reaches a baffle, some powder moves along the panel while some passes through the oval openings into the corners.
As the fill level rises, the eight openings continue to provide lateral flow paths. More even corner distribution can support more consistent contact between the bag bottom and pallet.
If the feeding rate is excessive, the central powder level may rise before material can move through the openings. Adjusting the filling rate may be necessary.
A baffle requires sufficient continuous fabric to restrict the separation of adjacent walls. It also needs openings that allow powder to reach the space behind the panel.
Openings that are too few or too small may restrict material flow. Excessive or oversized openings may reduce the continuous load-transfer area.
This design uses two 10 × 20 cm oval openings in each 35 × 44 cm baffle, creating a defined balance between internal flow and shape restraint.
Suitability still depends on particle size, bulk density, moisture condition, flowability and filling rate.
A filling trial should evaluate more than the final external shape. The four sides and corners should be observed at several stages during filling.
A persistent depression in one corner may indicate a twisted baffle, displaced opening, off-centre feeding position or powder bridging.
If all four sides bulge excessively, check baffle tension, actual filling weight and material bulk density.
After filling, measure the length and width at the top, middle and bottom, then record the maximum external dimensions.
| Observation | Possible cause | Recommended check |
|---|---|---|
| Full centre with empty corners | Feeding rate too high | Reduce the rate and observe flow through the openings |
| One corner remains depressed | Twisted baffle or displaced opening | Inspect the corresponding panel |
| Powder accumulates near openings | Agglomeration or poor flowability | Check moisture, lumps and particle size |
| One side bulges noticeably | Off-centre feeding or uneven baffle tension | Adjust feeding position and inspect the baffles |
| Uneven bottom contact | Different corner fill levels | Observe the bottom during staged filling |
| Interrupted discharge | Compaction or outlet bridging | Check powder condition and outlet behaviour |
| Filled dimensions vary between bags | Inconsistent weight or filling process | Standardize weight, rate and stopping point |

This Four-Baffle FIBC Bag is suitable for form-stable packaging, equipment filling, intermediate holding and palletized handling of graphite powder, mineral powder, industrial fillers, carbon-based powders and other dry industrial materials. Eight oval openings across the four baffles provide flow paths into the corner areas while the remaining panel sections restrain outward expansion. Powders that agglomerate, contain moisture or have limited flowability should be tested with the actual material.
Free-flowing dry powder can generally move more readily through the oval openings. Bridging or agglomerating materials require a filling trial.
Particle size alone is insufficient because moisture, surface friction, particle shape and compaction also affect flow.
High-rate filling may raise the central material level before powder reaches the corners.
Provide the equipment feed rate and test whether reducing it improves corner distribution.
The 60 × 60 × 60 cm value is a nominal dimension rather than a guarantee of identical dimensions at every filled position.
Measure the top, middle and bottom after filling with the intended powder.
The bag has a Φ30 × 30 cm bottom discharge spout. Continuous discharge depends on powder flowability, compaction and the outlet connection.
Powders prone to bridging may require vibration or other discharge assistance.
The baffle openings affect internal powder distribution rather than package leakage performance.
Fine-powder applications must also evaluate the coating, needle holes, seams, spout closures and liner requirements.
