Checking dimensions, colour and stitching does not prove that a graphite powder bag will work on the buyer’s filling line. Performance depends on the interaction between the bag, powder, filling equipment, pallet and handling method.
The same Baffle FIBC Bag can produce different filled heights, corner distribution and external dimensions when used with graphite powders of different particle sizes, bulk densities and flow characteristics.
This four-baffle construction should therefore be evaluated through an empty-bag inspection, filling trial, dimensional measurement and lifting test before production approval.
The bag contains four 20 × 35 cm internal baffles. Each baffle has one 10 × 30 cm oval opening and is installed 5 cm below the bag opening.
During incoming inspection, check whether all four panels are positioned consistently and whether any baffle is missing, twisted, misaligned or noticeably looser than the others.
The oval openings should also be inspected for position and edge condition. A displaced opening may contribute to uneven corner filling.
Baffles should not be excessively loose or tight. Uneven tension can affect both bag expansion and powder movement.
The production specification includes a top filling structure with a 10 cm tie. The finished spout diameter, length and equipment connection must still be confirmed.
An oversized filling spout may not be held securely by the bag clamp, allowing dust to escape around the connection.
An undersized spout may restrict the feeding rate or cause powder to accumulate around the inlet.
The tie closes the filling spout after loading, but it does not replace a defined sealing or dust-leakage test.
The trial should use the intended graphite powder rather than a substitute with substantially different flow characteristics.
Record particle size, loose bulk density, moisture condition and target net weight before filling.
Observe whether powder passes through all four oval openings and reaches the corners. If the central level rises while the corners remain empty, the filling rate or material-flow conditions may require adjustment.
The trial may be paused at 25%, 50%, 75% and 100% of the target fill quantity to identify when uneven distribution begins.
The nominal bag dimensions are 30 × 30 × 45 cm, but production acceptance should not rely exclusively on empty-bag measurements.
After filling, measure the length and width at the top, middle and bottom. Record the position and size of the maximum bulge.
For palletized handling, compare the maximum filled footprint with the pallet edges.
Testing several sample bags also helps determine whether variations come from filling weight, feeding rate, baffle position or stitching consistency.
The bag has four 5 × 55 cm lifting loops made from 45 g/m webbing. Each loop is attached to the body with two parallel stitching lines.
During trial lifting, confirm that all four loops can be engaged and loaded together. Check for bag inclination or one loop carrying the load before the others.
The bag profile may change when suspended. Inspect bottom balance, baffle tension and deformation around the loop attachment areas.
No SWL or safety factor is provided in the available specification. The permitted filling weight must therefore be verified through separate test documentation.
| Inspection item | Specification | Recommended check |

| Baffle opening | 10 × 30 cm oval | Inspect position and edge condition |
| Baffle position | 5 cm below the opening | Check installation height |
| Body fabric | 180 g/m², internally coated | Verify material configuration |
| Top and bottom fabric | 180 g/m², internally coated | Inspect fabric and seam construction |
| Baffle fabric | 90 g/m², internally coated | Inspect internal panel material |
| Lifting loops | 4 | Check position and symmetry |
| Loop dimensions | 5 × 55 cm | Match with forklift conditions |
| Loop specification | 45 g/m | Do not treat as tensile strength |
| Filling structure | Top filling with 10 cm tie | Match with the filling nozzle |
| Seam construction | Double-stitched folded body and bottom seams | Check skipped and incomplete stitches |
| UV configuration | 1% additive | Does not define outdoor service life |
| Application | Verification focus | Use condition |
|---|---|---|
| Small-batch graphite packing | Weight and fill height | Bulk density is confirmed |
| Graphite production-line collection | Filling-spout interface | Equipment dimensions match |
| Intermediate storage | Shape and closure | Storage environment is controlled |
| Palletized transfer | Maximum filled footprint | No unacceptable pallet overhang |
| Forklift handling | Loop engagement and load balance | All four loops can be engaged |
| Fine graphite packaging | Seam leakage and liner requirement | Actual powder testing is completed |
Specify particle size, loose bulk density, moisture condition, flow behaviour and agglomeration tendency.
These values are required to evaluate material movement through the baffle openings.
State the target net weight, permitted tolerance, expected filling height and required headspace.
The SWL must be confirmed separately because it is not included in the current specification.
Confirm filling-nozzle diameter, effective length, clamping method and feeding rate.
Automatic and semi-automatic lines may also require a defined bag-opening position.
Provide pallet dimensions, permitted overhang, rack clearance and the intended number of bags per pallet.
Acceptance should be based on filled dimensions rather than empty-bag measurements.
State whether a small amount of dust is acceptable and whether a separate PE liner or enhanced closure is required.
Internally coated fabric does not replace application-specific leakage or moisture testing.
Particle size, bulk density and agglomeration affect corner filling and final dimensions.
A substitute powder may not reproduce the actual filling behaviour.
Inspect installation height, opening direction and tension while the bag is empty.
After filling, compare the four sidewalls and investigate any pronounced one-sided bulging.
These are nominal dimensions. Woven PP is flexible, and powder applies lateral pressure during filling.
Baffles control expansion but do not make the filled dimensions identical to the empty dimensions.
Not necessarily. Fine powder may still escape through needle holes, seams and closures.
Sift-resistant seams or a separate liner may be required.
Compare the effective loop height with the forklift tine width, spacing and operating clearance.
All four loops should engage and carry the load as evenly as practicable during the trial.
No. A percentage alone does not establish an outdoor exposure period.
The UV test method, exposure data and operating environment must be reviewed separately.
The purchasing decision should be based on how the bag performs with the specified graphite powder—not simply on whether it contains four baffles.
Recording fill weight, filling time, corner distribution, maximum filled dimensions and lifting behaviour provides a practical approval standard for the production order.
