1700 N/50 Mm Fabric Strength Lithium Carbonate FIBC Bag With Coated Body

Product Introduction

This 1,700 N/50 mm Fabric Strength Lithium Carbonate FIBC Bag uses coated body fabric with a defined tensile-strength requirement for packing, storing and transporting 1,000 kg loads of lithium carbonate powder.

The main body uses 190 g/m² fabric with a specified tensile strength of ≥1,700 N/50 mm and a weaving density of 54 × 54 yarns per 10 cm. In addition to fabric weight, these values provide buyers with measurable references for evaluating the body material.

The bag has nominal dimensions of 108 × 108 × 125 cm and a rated load of 1,000 kg. Its internally coated body helps cover openings in the woven structure and reduce the risk of fine powder passing through the fabric.

1,700 N/50 mm Fabric Strength

The ≥1,700 N/50 mm value means that a 50 mm-wide fabric specimen must meet the specified tensile requirement. It is used to evaluate the material’s performance under tensile loading.

After lithium carbonate is filled into the bag, the body walls are subjected to material weight and lateral pressure. During lifting, the load is also transferred from the loop attachment areas into the body fabric. Fabric strength is therefore one of the parameters used in the bag’s structural design.

The documented body-fabric controls include:

• Body fabric weight: 190 g/m²
• Fabric tensile strength: ≥1,700 N/50 mm
• Warp density: 54 yarns/10 cm
• Weft density: 54 yarns/10 cm
• Fabric treatment: internally coated
• Stitch density: 10 stitches/10 cm
• Rated load: 1,000 kg

Fabric tensile strength is not the same as the rated load or complete-bag breaking load. Complete-bag performance is also influenced by stitching, loop attachment, bag dimensions and the actual lifting method.

Coated Body

The body uses internally coated fabric. The coating covers part of the woven openings and improves the fabric’s suitability for powder packaging.

The top and bottom panels use 185 g/m² internally coated fabric, while the four internal baffles use 130 g/m² internally coated fabric. The filling and discharge spouts use flexible 90 g/m² internally coated PE material.

The documented seam construction includes:

• Double-fold, single-stitch connection between the top panel and body
• Double-fold, double-stitch connection between the body and bottom panel
• Double-sided cotton tape at the top and bottom connections
• Single-sided cotton tape around the baffle connections
• Folded seam treatment around the filling and discharge spouts

These features help control powder around the fabric and seam areas. They should not be described as completely leak-proof or airtight without corresponding test data.

Application

This Lithium Carbonate FIBC Bag can be used for 1-ton packaging after lithium carbonate drying, screening or other powder-processing stages: during filling, the Φ45 × 60 cm top spout can be connected to weighing and filling equipment while the target load is controlled within 1,000 kg; after closing, the bag can be moved by its four cross-corner loops to pallets or finished-goods storage and then transported within the plant, by truck or in a shipping container; at a lithium battery cathode-material facility, the bag can be positioned above a discharge station and emptied through the Φ40 × 55 cm bottom outlet into a storage hopper, mixing unit or downstream processing system. For battery-grade lithium carbonate, liner construction, packing environment, metallic-contamination control and moisture requirements should be specified separately.

Specifications

Use and Confirmation Points

• Do not exceed the confirmed rated load of 1,000 kg.
• Fabric tensile strength does not replace the complete-bag safety factor or lifting test.
• Confirm that the bag volume matches the actual bulk density of the lithium carbonate.
• Where strict powder control is required, verify the seam construction through an actual filling test.
• Where moisture control is required, specify and verify a separate liner.
• Inspect the fabric for cuts, damage, open seams or coating defects before filling.
• Do not fill or lift a bag with visible structural damage.
