FIBC Manufacturing · Industrial Packaging
LUOYANG DUANHONG is a professional FIBC jumbo bag manufacturer delivering engineered bulk packaging, stable high-volume production and export-ready quality control.
About Duanhong
From woven polypropylene to container loading, the critical stages stay within one coordinated production system.
LUOYANG DUANHONG focuses on FIBC jumbo bags for mining, chemicals, construction materials and industrial powders. We translate material density, filling equipment, discharge method and export route into a confirmed bag specification, then control production and inspection against it.
Complete Manufacturing Process
A clear process connects raw material, fabric formation, bag assembly, inspection and export loading — reducing handoff risk and keeping every order aligned with the confirmed specification.
Resin and additives prepared to the confirmed fabric requirement.
Extruded tape is stretched and wound for stable tensile performance.
Circular and flat fabric is woven to the required width and weight.
Coating, liner and panels are prepared for the final bag configuration.
Loops, seams, top and bottom structures are assembled by trained operators.
Fabric, dimensions, sewing and finished-bag details are checked.
Approved bags are bundled, marked and loaded for export delivery.
FIBC Product Solutions
Select the filling and discharge configuration that matches your line. Each classic structure is a production starting point; size, fabric, loops, liner and printing remain fully configurable.
Open top · Flat bottom
A full-width open top on an economical flat base — the straightforward workhorse of bulk export.
View DetailsIndustry Applications
Our five application groups connect industry requirements directly to the correct FIBC structure, containment level and handling method.
High-density mineral concentrate that demands robust, dust-controlled FIBC packaging for export logistics.
A fine, dusty chemical powder that benefits from dust-tight FIBC configurations and clean discharge.
A high-density abrasive ore requiring heavy-duty FIBC bags with reinforced lifting for safe transport.
A fine, moisture-sensitive construction powder that benefits from dust-tight FIBC bags and liner protection.
Fine and active powders that require controlled filling, secure containment and clean discharge.
Why Choose Us
Bags engineered around your material, filling method and transport mode — not off-the-shelf compromises. Fabric weight, liner, top and bottom openings, and lifting loops are each specified for your product and locked before production.
Responsive production lines that scale to your order volume and deliver on your lead time. From a first trial batch to full container loads, the same line handles the range and holds your schedule as the reference.
Documented testing and inspection at every stage, from raw material to finished bag. Fabric weight is checked on arrival, sewing is reviewed during assembly, and each finished bag is inspected before packing.
Export-ready packaging and documentation for buyers across continents. Every shipment is arranged with the packing, marking and paperwork your destination requires, so customs and receiving go smoothly.

Quality Control
Every order is produced against a confirmed specification. Incoming material, fabric, sewing and finished-bag details are reviewed at defined control points before the shipment is released.
How We Work With You
Technical questions are resolved before production begins, and every milestone stays visible through sampling, manufacturing, inspection and shipping.
We start by learning what you pack — the material, its bulk density and particle size, and how it is loaded and discharged. These properties shape the first draft: fabric strength, liner requirement, and bag construction all follow from the product you move.
Together we set the working load, bag dimensions, fabric weight, and construction details such as top and bottom openings, lifting loops, and any liner. Every point is recorded so the bag is engineered for your exact handling line, not a generic stock size.
Before production begins, the specification is agreed and locked in writing — dimension drawing, fabric type, SWL, and all options. This becomes the single reference for the order, so both sides work from the same page.
Production follows the confirmed specification, with quality checks at key stages: incoming fabric weight, sewing during assembly, and final inspection before packing. Every bag must meet the agreed standard before it leaves the line.
We prepare the export documentation and arrange delivery from our factory to your port, with packing and marking matched to your transport plan. One handoff from order to arrival, so you can plan the receiving side with confidence.
