1.5 Ton FIBC Bulk Bag for Petroleum Coke – China Suppliers & Factory | Duffle Skirt & Bottom Discharge Spout

Our robust 1.5 ton capacity two-loop FIBC bulk bag is specifically designed for the storage and transportation of petroleum coke granules within mineral, carbon material, and refinery supply chains. Manufactured in state-of-the-art facilities in China, this industrial jumbo bag features a full open duffle skirt top for rapid bulk filling, complemented by a compact bottom discharge spout to ensure dust-free, controlled unloading. The reinforced cross corner X-shaped base construction effectively distributes the weight of granular loads, preventing deformation, bottom tearing, and material leakage during stacking, lifting, and long-distance ocean freight, This petroleum coke bulk sack is made from high-tensile virgin PP woven fabric and can be customized with anti-static treatment, inner liners, and leak-proof stitching strips, adhering to hazardous carbon particle transport standards. As reliable suppliers, we operate dual manufacturing plants in China and South Asia, offering custom-sized FIBCs and standalone PP base fabric rolls to global refineries, carbon processing factories, and mineral bulk packaging distributors

    Detailed Description

    Designed to address the transportation challenges of sharp, abrasive petroleum coke granules, our 1500kg rated two lifting loop bulk bag delivers robust structural performance for carbon raw material logistics, refinery bulk storage, and mineral cargo export. Distinct from regular general-purpose jumbo sacks, this petroleum coke FIBC integrates three core functional structures tailored to granular carbon media: wide top duffle skirt filling opening, narrow bottom discharge spout, and full cross X corner reinforced bottom.

    High-Efficiency Duffle Fill Skirt

    The oversized duffle fill skirt eliminates filling bottlenecks for high-volume petroleum coke feeding. Operators can directly connect large industrial hoppers to wrap the skirt around filling outlets, drastically cutting loading time while containing flying coke dust during bulk feeding procedures.

    Precision Discharge Spout

    The integrated small bottom discharge spout enables regulated, slow-speed particle release without fully hoisting or tilting the entire bag, ideal for automated production line feeding, secondary packaging, and quantitative material allocation at carbon processing plants.

    Cross X-Corner Reinforced Base

    Its signature cross X-shaped cross corner base is the key upgrade for abrasive petroleum coke. Conventional flat bottom FIBCs suffer concentrated stress points under heavy granular loads, leading to fabric wear, seam split, and coke particle spillage during stacking and cross-continental shipping. The X cross bottom distributes 1.5-ton weight evenly across four bottom corners, boosting tensile resistance against sharp coke grain friction and extending the service life of each industrial sack. Dual integrated lifting loops are sewn with multi-layer reinforced stitching to sustain full 1500kg load under repeated crane and forklift lifting cycles.

    Manufactured from high-density virgin polypropylene woven base fabric, this carbon material bulk bag avoids brittle recycled raw materials that risk breakage under heavy abrasive granules. Customizable functional upgrades include conductive anti-static fabric for combustible carbon dust environments, polyethylene inner liners to block moisture absorption, leak-proof cotton strips sewn along all stitching seams, and UV stabilizer treatment for outdoor stockpile storage. Beyond finished custom FIBC solutions, our vertical circular loom workshop supplies separate PP woven base fabric rolls to independent packaging manufacturers worldwide.
    With integrated production facilities based in China and South Asia, we fulfill small trial orders and mass bulk procurement for global refineries, graphite factories, carbon powder processors, mineral bulk cargo forwarders, and industrial packaging wholesalers. All structural dimensions, fabric weight, loop quantity, spout diameter, and safety load rating can be modified to match client-specific filling machinery, container loading standards, and international ocean transit regulations.

    Frequently Asked Questions

    What makes this bulk bag suitable for sharp petroleum coke granules?

    The bag is woven from 100% high-density virgin polypropylene fabric and integrates a cross X-corner bottom structure. This design prevents localized friction wear and fabric breakage caused by the abrasive edges of granular carbon materials during transit.

    How does the duffle skirt opening help with dust control?

    The wide duffle skirt can be directly wrapped around industrial feeding hoppers. This snug connection significantly accelerates high-volume loading while containing airborne carbon dust within the filling stream.

    Can the bag be customized for explosive carbon dust or humid environments?

    Yes. We provide conductive anti-static fabric configurations for combustible dust environments, polyethylene (PE) liners for moisture resistance, leak-proof cotton seam cords, and UV stabilization for open-air stockpiles.

    What is the safe working load (SWL) rating and loop construction?

    This model is rated for a 1500kg working capacity. It features two continuous lifting loops reinforced with multi-layer heavy-duty stitching to withstand repeated forklift and crane handling cycles.

    Do you provide custom dimensions and test reports?

    Yes. Dimensions, fabric weight, loop styles, and spout sizes can be customized to match your automated filling and discharging systems. Free fabric samples and full load test reports are available upon request.
