These Graphite Powder FIBC Bags use body fabric with specified minimum strength values of ≥1650 N in both warp and weft directions. The configuration is intended for graphite powder filling, factory transfer, temporary storage and transportation with a rated load of 1000 kg.
This product page focuses on the relationship between fabric strength and the complete load-bearing structure. Fabric strength is important, but it must be evaluated together with fabric weight, lifting-loop attachment, reinforcement patches, sewing density and actual handling conditions.
The production sheet records the strength value as ≥1650 N but does not identify the testing standard or specimen width. Therefore, it should not be rewritten as N/50 mm unless the manufacturer provides the corresponding test report.
FIBC woven fabric has two primary directions:
For this bag, both directions are specified at not less than 1650 N. Providing values for both directions is more informative than using a general description such as “high-strength fabric,” because the bag body experiences multidirectional stress during filling, lifting and movement.
However, the ≥1650 N value does not independently establish the total safe performance of the finished bag. A complete evaluation must also consider:
During lifting, the weight of the graphite powder is transferred from the bag body to the four cross-corner lifting loops. Stress is concentrated around the loop attachment areas, so the construction does not rely only on the strength of the main body fabric.
Each bag uses four 7 × 140 cm lifting loops made from soft webbing with a specified weight of 45 g/m. Four 14 × 20 cm reinforcement patches are positioned at the loop attachment areas.
The loops are sewn approximately 40 cm downward along the bag body using a diamond-shaped stitching pattern. The production requirements also specify at least three backstitching passes at the loop ends.
This creates a combined load path:
Graphite powder load → bag body → reinforced sewing area → cross-corner loops → lifting equipment
For stable handling, all four loops must be engaged correctly. Using only two loops, twisting the webbing or lifting with uneven fork positions can create concentrated stress that is not represented by the fabric-strength value alone.
| Customer concern | Relevant bag configuration | What should be confirmed |
|---|---|---|
| Body deformation during filling | ≥1650 N warp and weft strength | Powder bulk density and actual filling weight |
| Stress around lifting points | Four reinforcement patches | Loop positioning and stitching condition |
| Uneven lifting | Four cross-corner loops | All four loops engaged at the same time |
| Seam opening during handling | 9–12 stitches per 10 cm | Seam continuity before filling |
| Powder contact with woven fabric | Independent inner liner | Liner material and closure requirements |
| Filling connection mismatch | Top filling spout | Equipment outlet diameter and clamp type |
| Uncontrolled discharge | Bottom discharge spout with tie | Receiving hopper and discharge procedure |
| Limited sunlight exposure | 1% UV additive | Exposure duration and storage conditions |
The ≥1650 N specification should therefore be used as one part of the purchasing decision, rather than as a standalone guarantee of handling safety.

The ≥1650 N Fabric Strength Graphite Powder FIBC Bags are suitable for handling operations in which graphite powder is filled into one-ton packaging units, moved between production areas and warehouses, temporarily stored before processing, or transported to downstream industrial users.
Typical uses include:
The bag includes an inner liner, but the material of that liner is not identified in the production document. If the graphite powder has defined moisture, purity or contamination-control requirements, the liner material and thickness should be confirmed separately.
Before filling, operators should check the complete bag rather than examining only the body fabric.
Check for cuts, punctures, oil contamination, loose threads or damage around the seams. The production requirements specify a clean surface without oil, debris or fabric offcuts.
Confirm that the webbing is not twisted, cut or pulled away from the bag body. The reinforcement patches and diamond-shaped stitching areas should remain intact.
Make sure the liner is correctly positioned inside the bag and has not been punctured during storage or installation.
The documented rated load is 1000 kg. The filling system should be set according to the confirmed net weight and the bulk density of the graphite powder.
Confirm that the filling spout can be secured to the filling equipment and that the discharge outlet matches the receiving system.
