QINFENG Custom FIBC manufacturer since 2001
Custom FIBC · Since 2001
FIBCs precisely shaped around filling speeds, lifting methods, discharging conditions, warehouse stacking and overseas freight.
Manufacturing Evidence
From resin drawing and circular weaving to lamination, cleanroom sewing, cyclic top lift testing and bale pressing—every stage has a verifiable checkpoint.
Packing & Logistics
Custom high-density hydraulic bales, fumigated pallets, container optimization and clear FOB, CIF or DDP delivery terms matched to your destination.
Core Product Families
Large product views and structural outlines make each construction recognizable before tailoring dimensions, loops, liners and closures.

Custom FIBC Engineering
The interface turns a complex custom industrial packaging requirement into an orderly sequence your procurement and logistics teams can review with confidence.
Powder, granule, mineral aggregate, food ingredient, fresh produce, abrasive gravel or wet sludge.
500 kg to 2,000 kg capacity with guaranteed 5:1 single-trip or 6:1 multi-trip safety factor ratings.
Tailored footprint (e.g. 90x90cm, 105x105cm) and height configured for bulk truck, railcar or sea container.
Full open top, skirt/duffle closure, or custom diameter filling spout with tie-string to prevent dusting.
Plain flat base, standard discharge spout with petal cover, or conical bottom for cohesive materials.
Cross-corner, side-seam, tunnel loops, single/double point, or stevedore straps for harbor hook lifting.
Real-World Deployment
Different materials present unique flow dynamics, moisture risks, UV exposure, lifting challenges and discharge speeds.

Heritage · Since 2001
24+ years of dedicated export experience, zero subcontracting of core weaving, and an annual output capacity of over 1.2 million high-specification FIBC bags. Extrusion drawing, circular weaving, extrusion lamination, automatic cutting, flexo printing, sewing, metal detection and hydraulic packing are unified under one ERP system.
Explore Manufacturing →Visible Quality Control
Full batch traceability from resin lot numbers to finished pallet codes. ISO 9001 quality management with on-site top lift load test frames. Every batch undergoes yarn tensile tests, UV accelerated weathering, fabric burst tests, seam pull strength and cyclic top lift rig verification.
See Quality Control →Export & Sea Freight Support
Weekly vessel departures from Qingdao Port. Comprehensive trade term flexibility including FOB, CIF, CFR and door-to-door DDP services. High-pressure bale compaction, pallet fumigation (ISPM 15), weatherproof stretch hooding and container weight/cube optimization.

Every process station emphasizes what parameters are monitored and controlled—never generic machinery for decorative effect.
Virgin polypropylene tape extrusion with exact denier control, followed by circular and flat loom weaving.
Hot wire or ultrasonic cutting to prevent fraying, with multi-color flexographic printing of logos, handling labels and UN certifications.
High-strength lockstitch or chain stitch with dust-proof felt cords, reinforced lifting loops and form-fit liner insertion.
100% optical inspection on light tables, needle metal detection, hydraulic baling and fumigated pallet bundling.
Quality Made Visible
Independent laboratory test certificates and in-house batch reports are published with their applicable bag construction and project scope.
