One-Loop / Two-Loop FIBC

A bag lifted from one or two central loops instead of four corner loops. It suits light to medium loads handled by a single hook or crane where loop alignment is the operator's main constraint.

Direct factory B2B volume pricing
Size 75 x 75 x 100 cm to 95 x 95 x 120 cm (typical)
SWL / Safety Factor SWL 250-1,000 kg
Lifting loop Single central loop or two parallel loops
Top Open top, duffle, filling spout
Bottom Flat bottom or discharge spout
Fabric & coating 140-180 g/m2 woven PP, coated or uncoated
What it settles: Explains how a central lift changes the load path and why the working rating is usually lower than an equivalent four-loop bag.
Best for: Light to medium loads moved by crane, jib or single hook, where the handling team is small and the lifting space is tight.
Not the answer when: The site lifts with a four-loop frame or forklift forks, the bag is dragged or side-loaded, or the load is heavy enough that a four-corner lift…
Confirm before quoting: SWL, hook or jib geometry, loop height, whether any side pull or drag happens, and the material's bulk density.
/ Overview & Principle

HOW THIS BAG IS BUILT

Instead of four corner loops, the bag carries one or two lifting loops sewn across the top seam, usually with a reinforcement patch where the loop meets the body. The load path runs from the loop down through the body rather than from four separate corners, so the top seam and the loop anchorage take the whole working load.

Because the lift is central, the bag hangs symmetrically and can be handled by a single hook, a crane, or a forklift jib. That removes the need to line up four loops on a frame, which is the reason buyers choose it for tight spaces and small handling teams.

Operational summary:

A bag lifted from one or two central loops instead of four corner loops. It suits light to medium loads handled by a single hook or crane where loop alignment is the operator's main constraint.

/ Features

KEY DESIGN ADVANTAGES.

One hook, no loop alignment

A single pick point removes the four-loop alignment step, which shortens the handling cycle where lifting space is tight.

Hangs symmetrically under load

A central lift keeps the bag vertical, so the load does not swing or tilt the way an uneven four-loop pick can.

Less loop hardware to inspect

One or two anchorages means fewer loop seams to check and record in the pre-use inspection.

Fits small handling teams

It can be moved by one operator with a crane or jib instead of two people guiding a four-loop frame.

Fits confined lifting spaces

A central pick needs less clearance around the bag than a four-loop frame, which suits tight sheds, wash bays and container loading.

Two loops to share the pick

Where one anchorage concentrates the load too far, two parallel loops spread it between two points on the top seam.

CUSTOM CONFIGURATIONS & SIZING.

Size
75 x 75 x 100 cm to 95 x 95 x 120 cm (typical) Size is set from the fill weight and the material's bulk density.
SWL / Safety Factor
SWL 250-1,000 kg The central loop concentrates the load, so the rating is lower than an equivalent four-loop bag.
Lifting loop
Single central loop or two parallel loops Loop height and width follow the hook or jib you use.
Top
Open top, duffle, filling spout A duffle top is common where the load is filled by hand.
Bottom
Flat bottom or discharge spout A spout needs clearance under the bag while it hangs.
Fabric & coating
140-180 g/m2 woven PP, coated or uncoated Coating is chosen for moisture or dust control, not for strength.
Liner
No liner, loose PE liner A glued-in liner is not usually offered on this construction because of the loop anchorage.
Printing & packing
1-2 colours; baled or boxed Print area is limited by the loop reinforcement patch.

PERFORMANCE, TESTING & LIMITS.

1. Performance & working envelope

Rated rangeTypical working range is 250-1,000 kg SWL in a single-loop build, with the loop anchorage and top seam sized for the confirmed load. The rating assumes a single central pick with no side pull: any drag, side loading or off-centre lift changes the load path and must be confirmed per project.

2. How it is validated

TestingIn-house checks cover loop anchorage stitch count and pattern, seam pull on the top seam, fabric weight and filled dimensions. Third-party testing is arranged on request and quoted separately.

3. Limits

Where it is not the answerNot suitable where the bag will be lifted on a four-loop frame, dragged, or side-loaded, and not the right choice for heavy loads where a four-corner lift spreads the load better. It is also a poor fit for automated handling lines that expect four pick points.

Selection & Purchasing Guidance

Best For:
Light to medium loads moved by crane, jib or single hook, where the handling team is small and the lifting space is tight.
Consider Alternatives When:
The site lifts with a four-loop frame or forklift forks, the bag is dragged or side-loaded, or the load is heavy enough that a four-corner lift is safer.
Must Confirm Before Quoting:
SWL, hook or jib geometry, loop height, whether any side pull or drag happens, and the material's bulk density.
