QINFENG Custom FIBC manufacturer since 2001

QINFENG Baffle and U-Panel FIBC that hold a square profile
A Bag That Keeps Its Shape Under Load.

Baffle & U-Panel FIBC

Both keep four flat sides after filling, which is what makes a pallet stack and a container plan work: baffles sewn inside a tubular body, or a U-shaped panel that holds the corners without internal baffles.

QINFENG Tubular and Circular FIBC with a seamless body
One Body Seam Instead of Four.

Tubular & Circular FIBC

A body woven as a continuous tube: fewer seam paths for a fine powder to escape through, a smooth interior that empties cleanly, and the lowest cost per tonne of the standard constructions.

QINFENG dumpster, concrete washout and garden waste bags
Filled Where the Material Already Is.

Dumpster, Washout & Garden Waste Bags

Open-top heavy bags for material that is loaded on site rather than at a plant: construction rubble, concrete washout and green waste, each built around how it is filled, lifted and tipped.

QINFENG PP pallet covers, sling bags and rubble chutes
The Woven Parts That Travel With the Load.

Pallet Covers, Slings & Chutes

A cover that keeps rain and dust off a palletised load, a sling for awkward parts that have no lifting point of their own, and a chute that takes the dust and the breakage out of a long drop.

Showing 13 engineered FIBC solutions

Standard FIBC

The four constructions that cover most dry bulk filling. Everything below is built to the same drawing-and-sample process.

4 bags
Tubular FIBC Standard FIBC 600 × 400 px

Tubular FIBC

A seamless circular woven bag for free-flowing powders and granules; the lowest-cost standard construction where stackability is not the deciding factor.

Size 75 x 75 x 110 cm to 100 x 100 x 130 cm (typical)
SWL / Safety Factor 500 kg to 1,500 kg SWL
Top Open top, duffle top, filling spout, with or without skirt
U-Panel FIBC Standard FIBC 600 × 400 px

U-Panel FIBC

A flat-bottom FIBC whose body is one U-shaped panel joined to two side panels, giving a squarer filled footprint than a tubular bag. It is the usual answer when a filled bag has to sit level in a stack at a workable sewing cost.

Size 75 x 75 x 110 cm up to 100 x 100 x 150 cm (typical)
SWL / Safety Factor 500 kg to 1,200 kg at 5:1; 6:1 on request
Top Open top, filling spout, duffel top, or skirt with tie cord
Baffle FIBC (Q Bag) Standard FIBC 600 × 400 px

Baffle FIBC (Q Bag)

A four-panel FIBC with internal baffles or corner ties that hold a near-cube shape whether the bag is empty or part-filled. Built for loads that have to stack square in a container or on a pallet without the bag slumping.

Size Square base 85 x 85 x 85 cm to 105 x 105 x 120 cm
SWL / Safety Factor 500-1,250 kg at 5:1; 1,000-2,000 kg at 6:1
Top Duffle, filling spout, or open top with separate cover
Circular FIBC Standard FIBC 600 × 400 px

Circular FIBC

A seamless circular-woven bag closed with a round base, so free-flowing product empties completely and the body stays circular under load.

Size 70 cm diameter x 100 cm to 110 cm diameter x 130 cm (typical)
SWL / Safety Factor 500 kg to 1,500 kg SWL
Top Open top, duffle top, filling spout, with or without skirt

Specialty bags

Bags built around one job: waste handling, water and concrete, flood defence, or a PP accessory that travels with the load.

9 bags
Dumpster Bag Specialty bags 600 × 400 px

Dumpster Bag

A heavy-duty open-top bag for construction, yard and mixed waste, lifted on four corner loops or a stevedore strap. It is built for abrasion and puncture, not for dust control.

Size 3 yd³ (8 × 4 × 2.5 ft) in the USA · 3 m³ (200 × 150 × 100 cm H) in Australia
SWL / Safety Factor 1,000-1,500 kg · 5:1 safety factor
Lifting Lifting loops · stevedore strap
Ventilated FIBC Specialty bags 600 × 400 px

Ventilated FIBC

A woven bag with mesh panels or a perforated body so air moves through the load. It is specified for produce, wood and other materials that must not sweat in storage.

Size 1 m³: 100 × 100 × 100 cm · 1.5 m³: 100 × 100 × 150 cm
Ventilation options 4-side mesh · 2-side mesh + 2-side ventilated fabric · 4-side ventilated woven fabric
Mesh aperture Standard woven mesh apertures
Dewatering FIBC Specialty bags 600 × 400 px

Dewatering FIBC

A woven bag made with geotextile fabric so water drains out while the solids stay in. It is sized from the sludge, the flow and the containment requirement rather than from a working load alone.

Bag size Circumference 2-9 m, height 1-2 m (typical)
Fabric Woven geotextile, selected by opening size and permeability
Filling Top fill port or open top
Concrete Washout Bag Specialty bags 600 × 400 px

Concrete Washout Bag

A fabric bag placed where concrete wagons are washed out, so solids settle and the water can be handled separately. It keeps washout out of drains and site ground; the water rules remain the site's.

Size 80 x 80 x 80 cm to 100 x 100 x 100 cm (typical)
Fabric Woven PP body with a porous base panel
Top Open top, reinforced, with a splash skirt
Flood Control FIBC Specialty bags 600 × 400 px

Flood Control FIBC

A heavy woven open-top bag filled on site with local sand or aggregate and lifted into a temporary barrier.

Dimensions & Fill Weight 36”x36”x40” · 5 × 36”x36”x40”
Fabric & Coating 170 GSM + Lamination UV-stabilised PP
Top & Closure Open Top with stiffened hem, or Open Top with Flap Top
Garden Waste Bag Specialty bags 600 × 400 px

Garden Waste Bag

A breathable, wide-mouth woven bag for green waste, built open enough that fresh cuttings do not sweat in transit.

Size 90 x 90 x 90 cm to 110 x 110 x 110 cm (typical)
Fabric Woven PP, or PP mesh panels on two or four sides
Handling Four corner loops, or two side handles plus a lifting point
PP Pallet Cover Specialty bags 600 × 400 px

PP Pallet Cover

A woven cover that drops over a palletised load to keep dust, light and rain off without sealing the load.

Fabric Weight & Material PP fabric with customizable fabric weight to suit different load sizes and storage conditions.
Coating & UV Protection For outdoor applications, fabric can be specified with UV stabilisation to help resist degradation caused by prolonged sunlight exposure.
Size & Dimensions Made to fit your loaded pallet dimensions. Such as 1000mmx1200mmx1050mm
PP Sling Bag Specialty bags 600 × 400 px

PP Sling Bag

A woven sling with one or two central loops for lifting awkward loads that do not fit an FIBC.

Size Made to the length and girth of the load
SWL 250 kg to 2,000 kg SWL, set by the load
Lifting loops One central loop, or two loops at a stated spacing
PP Rubble Chute Specialty bags 600 × 400 px

PP Rubble Chute

A disposable woven chute that carries product from an FIBC outlet down to a truck or hopper without dust or breakage.

Diameter and length 60 cm to 90 cm diameter, cut to the drop height
Fabric 220 GSM woven PP, laminated
Attachment Tie collar, elastic collar, or clip ring
Application-Driven Selection

Not Sure Which Construction Fits Your Flow?

Bulk density, hygroscopic sensitivity, electrostatic risk, and warehouse stacking stability dictate the ideal bag structure.

Recommended: Tubular / U-Panel + Triple Sift-Proofing

Eliminates dust leakage and pressurized seam separation during high-speed filling.

  • Seam Defense: Non-woven polypropylene felt + twisted cord triple labyrinth stitching.
  • Body Fabric: Heavy circular woven fabric (180–220 gsm) coated with 30 gsm lamination.
  • Discharge Security: Petal-closure / swan-neck spout with protective dust flap.
