Two mineral materials weighing 1200 kg may require different bag volumes and construction details. Ore granules, mineral powder and sharp rock pieces differ in bulk density, flow behavior, moisture sensitivity and puncture risk.
This Mineral FIBC Bulk Bag has nominal dimensions of 90 × 90 × 90 cm. It uses 180 g/m² white uncoated fabric and is fitted with four lifting loops.
Its specified load capacity is 1200 kg. Before the bag is selected, the buyer should confirm the material’s bulk density, particle size, moisture content, filling process and transport environment.
A common purchasing method is to match the target filling weight directly to the bag’s stated load capacity. If the material weighs 1200 kg, the buyer selects a bag specified for 1200 kg.
This approach does not consider the relationship between material weight and volume. Two minerals with the same weight can occupy significantly different volumes when their bulk densities differ.
A high-density mineral may reach 1200 kg before the bag is completely filled. A lower-density mineral may fill the available volume without reaching the target weight.
Particle form creates additional differences. Fine mineral powder requires leakage and moisture control, while sharp ore pieces require an assessment of puncture and abrasion risks.
The 1200 kg figure is therefore only one selection condition. It cannot replace an analysis of the actual material.
The preliminary volume requirement can be calculated using:
Required volume (m³) = target filling weight (kg) ÷ bulk density (kg/m³)
The nominal dimensions of this FIBC are 90 × 90 × 90 cm, giving a theoretical geometric volume of approximately 0.729 m³.
The following examples show how bulk density changes the volume required for 1200 kg:
| Material bulk density | Theoretical volume required | Initial comparison with 0.729 m³ |
|---|---|---|
| 2000 kg/m³ | 0.600 m³ | Volume may be sufficient; weight control is important |
| 1800 kg/m³ | 0.667 m³ | Suitable for a representative filling trial |
| 1650 kg/m³ | 0.727 m³ | Close to the theoretical bag volume |
| 1500 kg/m³ | 0.800 m³ | Current dimensions may be insufficient |
| 1400 kg/m³ | 0.857 m³ | Bag height or dimensions should be adjusted |
These calculations are intended for preliminary selection. An FIBC is a flexible package, and usable volume is also affected by body expansion, top construction, filling equipment and material flow behavior.
For example, a material with a bulk density of 1500 kg/m³ requires approximately 0.800 m³ for a 1200 kg load. Compressing the material or overfilling the bag is not an appropriate solution; the bag dimensions should be reviewed.
The body uses 180 g/m² white uncoated fabric. This structure can be evaluated for dry granular materials that do not require a verified moisture or fine-powder barrier.
Uncoated does not mean waterproof or moisture-proof. A PE liner, coated body or external weather protection should be considered for outdoor storage, wet transport conditions or moisture-sensitive minerals.
Fabric weight alone is also insufficient for fine powder. Small particles may pass through woven gaps or sewing needle holes, requiring a liner, coated fabric or sift-resistant seams.
Sharp-edged ore requires a representative filling test. No puncture-resistance or abrasion-resistance data is provided, so the 180 g/m² fabric should not be described as suitable for every form of rock or ore.

These figures describe the available production specification. They do not independently establish a safety factor, cyclic lifting performance or dangerous-goods approval.
For dry materials with relatively consistent particle sizes, the main selection factors are bulk density, filling volume and the filled shape.
If the calculated volume is close to 0.729 m³, a representative trial should verify filling height, body expansion and the space required for closing the top.
High-density material may reach 1200 kg before the body is filled to its maximum volume. Filling should therefore be controlled by weight rather than by visual fill level.
Available bag volume must never be treated as permission to exceed the specified load.
Fine powder requires additional attention to dust leakage and moisture absorption. The buyer should provide a particle-size range and the acceptable leakage level.
Coated fabric, a PE liner or sift-resistant sewing may be required instead of the standard uncoated configuration.
Sharp material can apply concentrated pressure to small areas of the body. Drop height during filling and impact from large particles may increase the risk of fabric damage.
A representative trial should evaluate puncture, abrasion and handling performance using the actual material.
The lifting loops should be supported by the filling equipment so that the body is fully opened before material enters the bag.
Filling should be controlled by a weighing system. The target load should not be determined only by the visual shape of the filled bag.
All four loops should be engaged when the filled bag is lifted. Forklift tines must be smooth and free from burrs or sharp edges.
The bag should not be dragged by one loop. Loops should not be twisted, and sudden lifting, stopping and lateral swinging should be minimized.
The filled width may exceed the nominal 90 cm dimension. Warehouse and vehicle layouts should therefore use measurements taken from a representative filled bag.
Uncoated bags should be stored in a dry area and protected from rain, standing water, sharp rack edges and rough floors.
The supplier should receive the mineral name, bulk density, particle-size range, moisture content and information about sharp edges.
If bulk density is unknown, it should be measured from a representative material sample rather than estimated only from the mineral name.
Calculate the theoretical volume for the 1200 kg target and compare it with approximately 0.729 m³.
If the result is close to or above the theoretical bag volume, increase the bag height, change the base dimensions or reduce the filling weight.
Confirm whether the material absorbs moisture, generates fine dust or may be exposed to rain.
Use this information to select uncoated fabric, coated fabric, a PE liner or an additional sift-resistant construction.
Provide the filling-outlet dimensions, discharge method, forklift tine dimensions and warehouse-layout requirements.
These details help define the top, bottom, effective loop length and filled dimensions.
State whether the bag is intended for single-trip use, repeat use or dangerous-goods transport.
The available information does not provide evidence of a 5:1 or 6:1 safety factor or UN approval. Such requirements must be separately specified and verified.
Different minerals have different bulk densities. At the same weight, a lower-density material occupies a larger volume.
Required volume should be calculated by dividing weight by bulk density rather than selecting a bag only by its stated capacity.
Its theoretical geometric volume is approximately 0.729 m³.
Actual usable volume is affected by body expansion, top construction, filling height and material flow behavior. A representative filling trial is recommended.
No. The 180 g/m² figure defines fabric weight, while the uncoated construction has no verified waterproof or moisture-barrier performance.
Wet transport conditions require weather protection, a PE liner or a verified coated construction.
The available specification does not include puncture or abrasion test results.
The maximum particle size and shape should be provided, followed by filling, lifting and transport simulation using the actual material.
The bag is designed with four lifting loops, and all designated loops should participate in lifting a filled bag.
The ≥18000 N loop-strength value is not evidence that one loop can independently support the complete bag.
The available production specification is not sufficient to confirm dangerous-goods suitability.
Dangerous-goods transport requires the applicable UN packaging code, complete-bag test report and compliant markings.
