This nickel sulfate FIBC bag is specified with a minimum base-fabric strength of 1760 N in both the warp and weft directions. The balanced directional requirement provides a measurable basis for evaluating the woven body during filling, storage, and chemical material transfer, rather than relying on fabric weight alone.
The product uses a circular woven PP body made from 180 g/m² externally coated material. The top and bottom panels use 190 g/m² externally coated material. A PE inner liner, top filling spout, and bottom discharge spout are included for bulk packaging of nickel sulfate and similar chemical raw materials.
The production specification states:
Warp and weft are the two primary directions of the PP woven fabric. Applying the same minimum requirement to both directions helps control the basic mechanical properties of the bag body.
The 1760 N value represents a base-fabric strength requirement. It should not be treated as a complete indication of the load performance of the finished FIBC. Finished-bag performance also depends on fabric weight, lifting-belt design, seam construction, sewing density, spout structure, and the applicable test conditions.
The specification does not state the specimen width or test standard. Therefore, 1760 N should not be automatically converted to N/50 mm or directly compared with results obtained under different test methods.
The body uses 180 g/m² white PP woven fabric with an external coating. The woven base fabric provides the main structural layer, while the coating helps cover the openings between woven tapes when packaging smaller chemical particles.
Coating does not replace fabric-strength verification. Fabric weight, base-fabric strength, coating position, and coating condition should be checked separately.
The top and bottom panels use 190 g/m² externally coated material. The bottom panel connects with the discharge structure and cross-bottom lifting belts, making panel dimensions, opening position, and seam construction relevant selection factors.
The production instructions include double-fold and double-line seam structures. Sewing density is specified at 9–12 stitches per 10 cm.
After the base fabric meets its strength requirement, the different fabric sections must still be connected through controlled seam construction. Inconsistent seams, folding widths, or stitch density can create localized connection issues that cannot be evaluated from the base-fabric value alone.

This 1760 N fabric-strength nickel sulfate FIBC bag can be used for:
Before using the bag for another chemical material, confirm particle size, bulk density, flowability, chemical compatibility, and the required liner and coating configuration.
| Related Parameter | Why It Should Be Checked with 1760 N |
|---|---|
| Warp and weft results | Both directions should be reviewed rather than relying on a single-direction value |
| Test method and specimen width | Results from different standards or specimen dimensions may not be directly comparable |
| Fabric weight | Fabric weight indicates material mass per unit area but does not replace strength data |
| Coating position | Internal or external coating should be confirmed according to the required material-containment structure |
| Seam construction | Seam type, folding method, and 9–12 stitches per 10 cm affect the connection between fabric sections |
| Lifting-belt design | Belt width, quantity, position, and sewn length must work with the woven bag body |
| Top and bottom panels | These sections connect with the spouts and lifting structure and should be assessed separately |
| PE inner liner | Liner dimensions and thickness should match particle size, moisture sensitivity, and cleanliness requirements |
| Spout dimensions | Filling and discharge openings should match the equipment and material flow characteristics |
| Finished-bag testing | Base-fabric data cannot replace lifting, drop, or other finished-bag performance tests |
For this configuration, the 1760 N fabric requirement should be evaluated together with the 180 g/m² body fabric, 190 g/m² top and bottom panels, four cross-bottom lifting belts, and specified seam construction.
Not necessarily. The production sheet states a minimum fabric strength of 1760 N but does not specify the specimen width or test standard. A complete test report is required before expressing the value as N/50 mm.
No. Fabric weight represents the mass of material per unit area. Actual strength also depends on the PP resin, tape dimensions, weaving density, warp and weft structure, and manufacturing process.
The coating mainly covers the woven surface and supports material containment. It should not be treated as a replacement for base-fabric strength data. Mechanical performance should be evaluated using fabric results, seam construction, and finished-bag testing.
No. Material bulk density, particle size, flowability, chemical compatibility, liner thickness, spout structure, and actual filling conditions must also be considered.
