Machine overview
Application and operating principle
The LU-FSL12 is designed around throughput: twelve narrow sachets are formed and filled in parallel from a wide reel. It is particularly relevant to free-flowing, small-granule products packed in compact single portions.
Well suited to
- Sugar and sweetener sticks or sachets
- Salt and seasoning portions
- Free-flowing food granules
- High-volume hospitality and foodservice packs

Common options and engineering decisions
- Alternative lane arrangements and pack widths
- Volumetric cup or compatible granule dosing configuration
- Counting and bulk collection after cutting
- Date coding and registration control for printed film
Performance validation
Confirm with product and film trials
Target output and dose repeatability are affected by product flow, environmental conditions, sachet length, film sealing window, changeover and quality-control settings. Supply representative product and production film for a meaningful test.
Any stated speed, range or accuracy is an indicative reference rather than a universal guarantee. Contract acceptance criteria should be documented for the final configuration.

LU-FSL12 questions
Does every product suit twelve lanes?
No. Multi-lane systems work best when the product flows consistently and the sachet is narrow enough to fit the web layout. Product and film trials are essential.
How is the 600 mm reel divided?
The reference arrangement uses twelve lanes at approximately 50 mm per lane. Sealing margins and final sachet width must be confirmed during tooling design.
Can the machine make stick packs?
The narrow back-seal format is related to stick-pack production. Exact dimensions, seam position, cut pattern and product dose must be engineered for the application.
Your next step. Send a representative product sample, target dose, sachet drawing, film specification and required output. Lancing Ltd will confirm the practical machine configuration, trial plan and acceptance criteria for your application. See related machine information.

Production specification for LU-FSL12
Match the twelve-lane web to the granule, lane pitch and pack test
The LU-FSL12 is presented for compact, free-flowing granule sachets. Particle dimensions, lane pitch, film registration and product fall must remain compatible across twelve channels, and every lane should be included in dose and seal checks.
Project questions to answer before final specification
- What are the minimum and maximum particle dimensions, normal fines, fragility and tendency to bridge or segregate?
- Does the product and dose fit the proposed lane pitch, forming path and reference 40–80 mm pack length?
- What total web drawing defines the back seals, print repeat, cross cut, tear notch and any perforated strip arrangement?
- How will product be divided evenly across twelve lanes during normal refill and after a stop?
- What dose, seal and accepted-output sampling plan will identify individual lanes rather than only mixed finished packs?
Particle flow and the cross-seal timing are linked
Small free-flowing granules can continue to fall after the dosing command if the feed path is not controlled. Cross jaws must close only after the product has cleared the seal area, while excessive delay reduces output. The trial should therefore observe both dose consistency and trapped particles at the intended cycle.
The published web reference indicates a compact lane arrangement. Product size and the usable opening in each forming path must be checked so granules do not bridge, bounce out or damage the film and seals.
| Product distribution | Run the intended hopper and lane-feed arrangement through start-up, stable production and refill while sampling every lane. |
|---|---|
| Lane dose check | Label sachets by lane and compare the agreed weight or count criteria across the full web. |
| Seal contamination | Inspect cross seals for trapped granules and apply the agreed integrity test to samples from each lane. |
| Film registration | Check the 600 mm-class web drawing, lane pitch, back seals, print, cut and tear features using production-representative film. |
| Accepted output | Count conforming sachets and record lane rejects, product feed interruptions, normal quality checks and downstream collection. |
When a weighing or wider single-lane route may be better
Larger, irregular, fragile or mixed pieces may not suit narrow twelve-lane forming paths. A compact weighing machine can trade headline output for a wider product path, easier access and a dosing principle aligned to larger target weights.
Record the configuration that produced the result
A useful trial record identifies the product and film batches, dose setting, sachet dimensions, forming and sealing parts, coding setup, operating speed, stops, rejected packs and quality checks. Retained samples should be labelled so results can be traced to the lane, recipe or test condition where relevant.
The final quotation and acceptance schedule should distinguish indicative catalogue references from the values that will be demonstrated with the agreed product, pack and utilities.
Additional buyer questions
LU-FSL12 project questions
Can the LU-FSL12 run irregular pieces?
Suitability depends on particle dimensions, shape, fragility, lane opening and dosing method. Representative product should be tested because narrow channels can bridge or damage larger pieces.
How is product shared across twelve lanes?
The final feed and distribution arrangement must be specified for the product. The acceptance test should reproduce normal refill and verify every lane.
What does the reference length tolerance mean?
It is a configuration reference, not a universal acceptance guarantee. Final print-to-cut and pack-length criteria should be agreed with the actual film and operating conditions.
Can the machine produce connected strips?
A perforated or strip arrangement may be possible depending on cutting and sealing tooling. The required presentation must be shown on the web and finished-pack drawing before manufacture.
Define the project around your product and pack
Send the application data needed to assess the LU-FSL12
Provide representative product, every required dose and sachet size, film details, accepted output, utilities, cleaning and inspection requirements. Lancing Ltd can then confirm whether the LU-FSL12 is the correct starting point and define the trial scope.
Model-specific lane assurance
Link LU-FSL12 granule flow, lane pitch and cross-seal timing
Small granules can remain free-flowing while still bouncing, bridging, segregating or entering the transverse seal. Use lane-identified samples and the production feed arrangement.
Product feed
Record particle range, density, fines, fragility and the hopper/refill method. Observe distribution across all lanes before and after replenishment.
Lane and web
Issue the numbered web drawing and verify lane pitch, back seals, artwork, code, cut and tear features with production-intent film.
Accepted pack
Measure the agreed mass or count by lane, inspect granules in the seal, apply the integrity test and record accepted output after rejects.
