Dry industrial powder packaging must accommodate lateral material pressure, pallet dimensions and restricted warehouse positions. Conventional flexible bags may bulge after filling and occupy more space than their empty dimensions indicate.
This 180 g/m² Internally Coated Baffle FIBC Bag is intended for the batch storage of graphite powder, mineral powders, carbon-based powders and other dry industrial materials.
Its primary purpose is not prolonged outdoor protection. The coated fabric and four-baffle structure are intended to support controlled indoor storage, a more consistent filled profile and planned pallet use.
2. 180 g/m² Internally Coated Body
The body, top and bottom use 180 g/m² internally coated woven PP fabric. Using the same specified weight across these areas allows buyers to verify the material configuration of the complete external structure.
The internal coating can reduce powder entering the openings of the woven fabric. Overall dust control still depends on the seams, filling closure and any additional sealing components.
The 180 g/m² value identifies fabric weight per unit area. It does not establish the safe working load, which must be supported by SWL, safety-factor, loop-strength and complete-bag test data.
3. Four Baffles for a Controlled Storage Footprint
Four 20 × 35 cm internal baffles connect the four internal corners. These panels restrict outward expansion caused by powder pressure and help the filled package maintain a more controlled external profile.
Each baffle contains one 10 × 30 cm oval opening. The openings allow powder to enter the corners and reduce the possibility of isolated voids forming behind the panels.
The baffles use 90 g/m² internally coated fabric and are installed 5 cm below the bag opening. This position covers the main storage area while preserving space for top filling and closure.
The baffle construction can help control the filled dimensions, but it does not independently establish stacking suitability. Stacking also requires load, pallet and compression-test verification.

4. Dust and Environmental Control During Storage
Internally coated fabric can improve the barrier provided by the woven material, but it should not be described as completely moisture-proof or leak-free.
Fine powder may still escape through needle holes, body seams or the filling closure. Fine graphite, carbon or mineral powders may require sift-resistant seams, filler cord or a separate PE liner.
Moisture-sensitive materials also require a defined liner thickness, closure method and acceptable warehouse humidity range. Internally coated fabric does not replace application-specific moisture testing.
The bag contains a 1% UV additive, but no exposure duration or outdoor service-life test is specified. It is more appropriate for controlled indoor storage and limited outdoor handling.
5. Specific Storage Applications
Graphite Powder Batch Storage
The bag can be used to separate graphite powder awaiting inspection, approved material and powder scheduled for the next production stage.
Fine graphite applications should evaluate dust leakage around seams and determine whether an independent liner is required.
Industrial Mineral Powder Storage
The four-baffle construction may be used for mineral powders, industrial fillers and other dry powder materials stored indoors.
Filled dimensions, pallet edges and operating clearance between adjacent bags should be checked before warehouse positions are assigned.
Small-Batch Powder Packaging
The nominal 30 × 30 × 45 cm dimensions are suitable for formulation batches, pilot production, sample packaging and intermediate stock.
The theoretical geometric volume is approximately 40.5 litres, but usable capacity depends on headspace, internal baffles and powder condition.
Palletized Warehouse Handling
The baffle structure is relevant to storage operations with defined pallet footprints and package-arrangement requirements.
The maximum length and width at the top, middle and bottom of the filled bag should be measured and compared with the pallet dimensions.
Intermediate Production-Line Storage
The top-filling structure can receive powder from a hopper, screw conveyor or filling machine for temporary storage between production processes.
The filling spout must be matched to the equipment outlet, bag clamp and required feeding rate.
6. Storage Selection and Handling Guidance
Before selection, provide the powder name, particle-size range, loose bulk density, target net weight and expected storage period. Hygroscopic, agglomerating or dusty materials may require an additional liner or sealing structure.
Filling weight should be calculated from usable volume and bulk density. The available production sheet does not provide an SWL, so the bag should not be described as a 1-ton or 1,000 kg product.
After sample filling, measure the actual profile at the top, middle and bottom. Compare the results with pallet dimensions, rack clearance and spacing between adjacent packages.
The warehouse should remain clean and dry, and filled bags should be protected from continuous direct sunlight. Place them on level pallets away from floor moisture, sharp edges and high-temperature equipment.
Stacking suitability cannot be established from the baffle structure alone. Confirm SWL, filled-bottom condition, pallet capacity and relevant stacking-test results before multi-level storage.
