One-Loop / Two-Loop FIBC
A bulk bag lifted from one or two central loops instead of four corners — quick single-hook handling for light to medium loads, with a lower working rating to match.
A one-loop or two-loop FIBC is lifted from the middle of the bag rather than from four corners. The whole working load passes through one or two anchorages instead of four, and the bag hangs vertically.
That is useful in a small plant: a single hook on a crane or jib replaces a four-loop frame, and there is no loop alignment step before the lift. It is also useful where the bag has to come out of a tight space, because a centrally hung bag does not swing the way a poorly balanced four-loop pick does.
The trade-off is the load path. Concentrating the load in one or two anchorages lowers the working rating compared with the same body built with four corner loops, and it rules the bag out where it will be dragged or side-loaded. Tell us how you lift and whether anything drags the bag, and we will set the loop anchorage accordingly.
Product 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.
Core Construction
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.
Key Benefits
| Benefit | Why It Matters |
|---|---|
| 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. |
Configuration Options
| Option Group | Available Range | Notes |
|---|---|---|
| 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 & Range
Typical 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.
Validation & Testing
In-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.
Limitations
Not 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 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.

Lifting equipment used at your site Required
Single hook, crane, jib or forklift forks — the loop geometry follows this.
Required SWL and safety factor Required
The central lift concentrates load, so we may quote a lower rating than a four-loop bag.
Material and bulk density Required
Bulk density in kg/m3 sets the bag volume for the weight you need.
Filling and discharge method Required
Open top, duffle or spout on the way in; flat or spout on the way out.
Any dragging or side pull during handling
Say so plainly — it changes the loop anchorage we specify.
