One- and Two-Loop Bulk Bags for Hook-Lift Filling Lines
If your filler uses a hook and needs a wide mouth, compare the full-width single-loop sample with a two-loop design and duffle skirt. Send the hook profile, available height and minimum mouth width. Check these on an empty sample first and use the approved drawing for any loaded trial.
Before requesting a sample
- The starting specificationA single gathering point and two separate loops can meet different pickup geometries. The actual hook, lifting head and filling opening decide which candidate enters the shortlist.
- Inputs for your first reviewProvide equipment drawings and any obstruction at the hook.
One- and two-loop candidates
Qingdao Novapack Packaging Co., Ltd. manufactures woven polypropylene FIBCs in Qingdao, China. Tell us how you will fill and handle this bag so we can review the drawing, components and the checks you need on the selected build.
Our catalog includes a single-loop bag with a full-width opening and a two-loop bag with a duffle skirt. Ask for a drawing of each shortlisted configuration.
The actual hook, lifting head and filling opening decide which candidate enters the shortlist.
Use the result to rule out unmatched models before requesting a production quote.
Supply a hook profile, throat and clearances with the required width of the opening. An empty fit check lets you verify interfaces before your site authorizes handling a loaded sample.

Loop Placement and Top Conversion
The cut top panels or skirt set the usable mouth; the webbing layout sets how the bag presents to the hook. Compare where each loop is attached, the space above the filling head and whether the skirt can move clear of it. Confirm the base construction for the receiving station before you approve the sample.
Technical background PP tape for woven packaging and FIBC fabric
Single-Loop White Bulk Bag with Full-Width Filling Opening
Custom FIBC Bulk Bags Made to Your DrawingLoop location and the top cut determine where the bag hangs and how much material is available to the filler. Top skirt and pickup details should be dimensioned separately.
Keep the drawing of the mouth and pickup geometry together for the sewing review.
A single gathered lifting point
Ask for the loop geometry and the opening width that remains available at the filling station. Have your handling team review the hook arrangement for the proposed layout.
- Measure the single pickup at restCompare the bunched lifting point and hook access on the approved empty sample. Check how it approaches the filling head as the site team sets it up.
- Acceptance recordRecord hook size, clearance and the model approved by the responsible site team.
A wide filling mouth on the sample
Record the bag opening without load and where it sits relative to your filling head or mouth frame. Check which edges the operator needs to access.
| Technical check | The measured flat fabric size is different from the usable opening around a suspended or supported fill station. Mark where equipment or a closure covers part of the mouth. |
|---|---|
| For approval | State the clear opening and fitting method after an empty station check. |
The two-loop layout and top skirt
On a two-loop design, compare loop position and the movement of the top skirt when your equipment changes from bag placement to filling.
Two lift points can influence space for the skirt and filling head. Identify where each loop should sit and whether the skirt can remain clear of the intended clamp.
Request a drawing that identifies both loops and the free skirt material.
An empty-bag interface check
Start with an empty sample and record the fit at the hook, opening and filling head. Use the result to plan any approved loaded trial with the site team.
- Sign off empty fit before loaded useCompare insertion and release clearances, operator access and movement around the station. Keep an empty fit pass distinct from a rated use decision.
- Acceptance recordRecord pickup hardware, station conditions and sample ID at the signed checkpoint.
The exact rating for each candidate
Keep the loop geometry, label and approved drawing together. Request records that apply to the construction and proposed handling conditions.
| Technical check | Ask for the designation, load and applicable construction record for each loop arrangement and base. Have the equipment owner review the exact setup. |
|---|---|
| For approval | File a separate receiving reference for each approved model. |
A base that fits the next step
Select the base along with the top. A flat-base design and an outlet design give the receiving team different options in its process.
- Carry the base through to the next operationA top that fits the line can leave a base that is inappropriate for the pallet or discharge method. Measure the settled footprint and intended lower interface.
- Acceptance recordTie filling, handling and discharge to the same drawing revision.
A trial request for your filling line
Send the hook profile, minimum required top opening, clearance and target fill. Include the emptying method and the test checks for both configurations.
Include photos, hook or head geometry, mouth size, contents and proposed load and quantity.
Request comparable sample drawings with unresolved interface items marked.
