Application-Driven Engineering
When Standard Bags Fall Short.
Standard off-the-shelf bulk bags frequently lead to costly failures: dusting during filling, container space waste, forklift handling snags, or electrostatic hazards. Tailored engineering eliminates these vulnerabilities before first dispatch.
Material Chemistry & Physical State
Bulk density determines volume and elongation; ultrafine particle sizes (micron-level titanium dioxide, carbon black) require triple felt seams or form-fit liners to prevent airborne contamination.
Filling Line & Dust Control Integration
Spout diameters must seal airtight against your automated packing station. Specialized de-aeration vents, conical tops, or duffle openings ensure rapid flow without ballooning or blowouts.
Lifting & Warehouse Handling Rigs
Single-point cranes, stevedore straps for marine breakbulk, or automated forklift tines dictate loop height, reinforcement sleeves, and cross-corner positioning to eliminate rigging tilt.
Intermodal Stacking & Container Optimization
Baffle bags (Q-Bags) maintain rectangular geometry under hydrostatic pressure, preventing rounded bulging and enabling 2-high stacking inside 20ft/40ft ocean shipping containers.
Controlled Discharge & Operator Safety
Full-open release bottoms for sticky wet cake, iris-controlled spouts for metered dosing, and pyrotechnic rip-cords ensure operators never place limbs beneath suspended 1.5-ton loads.
Hazardous UN & Static Protection (B / C / D)
In explosive vapor or flammable dust zones, standard bags pose severe spark risks. We engineer conductive grounding interconnections (Type C) and dissipation fabrics (Type D) with verifiable resistance.
Engineering Capabilities Matrix
Six Customization Dimensions.
Every single component of our FIBCs can be specified to match exact mechanical, thermodynamic, and regulatory conditions. Click each dimension to inspect options and manufacturing dies.
Engineered Geometry For Maximum Stability
The main bag geometry determines structural footprint, lateral deflection, and stacking integrity. We fabricate all four primary international body styles under rigorous ISO 21898 testing.
Seamless Integration With Automatic Packing Heads
Top configurations must match your plant chute size, feeding speed, and atmospheric dust capture systems. Customizable tie cords and protective flaps prevent cross-contamination.
Zero-Spill, Safe Bottom Unloading Configurations
Whether you require metered dosing into a processing reactor or rapid dumping of construction gravel, our discharge systems are built to withstand immense bottom hydrostatic weight without rupturing.
Heavy-Duty Webbing Tested For 6:1 Multi-Trip Safety
Woven in-house using high-tensile polypropylene filament yarn. Loops are engineered with bespoke elongation curves and abrasion wear sleeves to match your specific crane hooks and tines.
Virgin PP Weaves, Extrusion Lamination & Specialized Liners
From high-permeability ventilated strips for drying crops to multi-layer barrier co-extrusions that resist hygroscopic moisture, we engineer fabric specifications from 120 GSM up to 260 GSM.
Sift-Proof Gaskets, Multi-Color Flexo & Barcode Traceability
We prevent product leakage through needle penetrations with specialized polypropylene filler cords and non-woven felt cords. Add your corporate brand identity with high-definition in-line flexographic printing.
From Drawing To Bag
Your Sketch On The Left. The Bag On The Right.
Most custom jobs start as a pencil drawing with two or three dimensions written on it. Drag any handle to slide between the sketch we received and the bag that came off the line, or focus a handle and use the arrow keys.

Quality & Reliability Protocol
From Specification to Mass Production.
We never skip engineering validation. Our 5-stage qualification process guarantees that the physical big bag arriving on your dock performs exactly as modeled.
Six-Point Requirement Clarification
We confirm your material bulk density, automated filling spout diameter, forklift loop clearance, stacking height, discharge valve, and target country compliance.
Stage 1 InputFactory Engineering Technical Review
Our engineering leads calculate precise fabric grammage (GSM), yarn denier, stitch density, and safety factors to avoid over-engineering or under-strength risk.
CAD & Spec SheetCustom Sampling & Prototyping
A physical pre-production sample is sewn in 5-8 business days using true production-grade virgin PP fabric, custom loops, and approved flexographic print proofs.
5-8 Days TurnaroundRigorous In-House Rig Testing
Samples undergo cyclic top lift test (70 cycles @ 2x SWL followed by 6x/5x SWL burst), drop tests, loop tear test, and UV acceleration before client sign-off.
ISO 21898 RigSealed Sample & Production Lock
The verified sample is assigned an immutable version number (Rev A/B/C). First-piece inspection and in-line QA check every production batch against this golden record.

What We Cannot Ethically Promise Without Technical Verification
No Blind "Safe Working Load" Guarantees
We will not quote a 2,000 kg load rating based purely on photos or generic descriptions without calculating true bulk density and top lift tension vectors.
UN Dangerous Goods Testing Rigor
UN certification requires physical package-level drop, topple, and tear testing at accredited test labs. We cannot apply UN codes based solely on ISO 9001 factory compliance.
Zero-Loss Powder Guarantees Without Felt Proofing
For sub-100 micron powders, standard woven fabric will weep under transit vibration. We require sample sift tests or form-fit liners before committing to zero dust leakage.
