LU-SPL6 verification notes
How to read the LU-SPL6 data before a project quotation
The LU-SPL6 information on this site gives a useful starting point for an automatic L-sealer and heat tunnel route. The listed packaging speed of 15–30 bag/min, POF / PE film compatibility and maximum pack-size notes should be checked against the actual product, film and operator or conveyor conditions before purchase.
A sample review should confirm whether the product stays square through the infeed, whether the sealing position leaves an acceptable film allowance, whether the tunnel removes wrinkles without overheating the pack, and whether the pack is cool enough at discharge for handling or case packing.
| Selection point | What to confirm | Why it matters |
|---|---|---|
| Listed speed | 15–30 bag/min is shown for the route. | Treat this as product and film dependent; verify with pack dimensions, infeed and tunnel settings. |
| Film compatibility | POF / PE film is listed. | Film thickness, centre-fold width and perforation still need confirming for each product. |
| Maximum package size | W+H ≤ 700mm, L+H ≤ 800mm, H ≤ 150mm is listed. | Use the largest real pack tolerance when checking suitability. |
| Finished-pack quality | Check seals, wrinkles, dog-ears, film clouding and barcode visibility. | Commercial acceptability depends on the finished pack, not only machine fit. |
Information to prepare before a quotation
- Product width, length and height, measured at the largest tolerance rather than only nominal size.
- Film type, film thickness, centre-fold width and whether packs need perforation for trapped air release.
- Target output in packs per minute and whether the operator will feed by hand or from an upstream conveyor.
- Required finish: loose transit wrap, tight retail presentation, label visibility, barcode visibility or tamper evidence.
- Available utilities, floor space, conveyor height and downstream packing or inspection requirements.

Buyer FAQs
Is LU-SPL6 suitable for every carton?
No. Suitability depends on carton size, stability, film type, tunnel finish and the required output.
What conditions affect the 15–30 bag/min speed?
Pack dimensions, feed consistency, film thickness, sealing dwell, tunnel dwell and cooling all affect real output.
Can the machine use both POF and PE film?
POF / PE film compatibility is listed, but each film should be checked for thickness, centre-fold width and shrink behaviour.
Why is cooling important after the tunnel?
Warm film can mark, loosen or distort if handled immediately, so discharge and downstream handling should be considered.
What should be sent for a sample review?
Product samples, dimensions, film details, photos, pack finish requirements and target output are the best starting evidence.

LU-SPL6 validation
How to confirm whether the LU-SPL6 route suits the application
The LU-SPL6 is the model-level route, so application limits should be checked against the actual pack and film rather than assumed from a headline figure. The listed operating range should be reviewed against the product and film being tested. A short, stable carton may run differently from a taller, lightweight or irregular product, even when both are technically inside the same broad shrink wrapping category.
| LU-SPL6 check | What to verify | Acceptance evidence |
|---|---|---|
| Product envelope | Compare the product width, length and height with the listed package-size conditions already shown on this page. | Largest pack clears the sealing area and tunnel without forcing or bridging. |
| Film behaviour | Test the proposed POF or PE film at realistic temperature, dwell and conveyor settings. | Seal is closed, film is not scorched and the corners shrink acceptably. |
| Output target | Confirm the required pack rate with operator feed, infeed spacing and tunnel speed included. | Saleable packs are produced at the required speed, not only mechanically cycled. |
| Finished presentation | Check label visibility, barcode visibility, air release and whether the wrap is protective or display-quality. | Finished samples match the buyer’s retail or transit requirement. |
Using the machine video responsibly
The video supplied with the site can help a buyer understand the process route, but it should not be treated as proof that every product will run at the same output or finish. Suitability still needs sample packs, film details and layout information.

LU-SPL6 application evidence
How LU-SPL6 suitability should be checked before order
The LU-SPL6 information is strongest when it is tied to the product and film conditions. Output, pack quality and heat tunnel finish depend on product envelope, operator or conveyor feed, film specification and settings. The stated range should therefore be treated as application-dependent rather than universal.
Before ordering, Lancing should review sample dimensions, photos, film type, required finish, site utilities and acceptance criteria. Where possible, a sample pack or video review helps identify seal position, trapped air, distortion and cooling issues before the machine is installed.
| Point to confirm | What Lancing checks | Why it matters |
|---|---|---|
| Model fit | Pack width, length, height and stability against the stated machine envelope. | Prevents specifying a system around a product that is close to a limit. |
| Film fit | POF or PE film route, film thickness, centre-fold width and perforation need. | Affects sealing dwell, tunnel recovery and pack presentation. |
| Utility fit | Available power, compressed air where required, access and machine footprint. | Confirms practical installation before shipment or commissioning. |
| Acceptance fit | Good-pack standard, sample photos and reject examples. | Creates a practical benchmark for FAT, SAT and operator sign-off. |

Final specification FAQs
Is the quoted speed guaranteed for every pack?
No. Output depends on product size, film behaviour, operator or conveyor feed and the finished-pack quality required.
Can LU-SPL6 run POF and PE film?
The route is presented for POF and PE film applications, but suitability should be confirmed against the exact film and product.
What should be checked at acceptance?
Pack quality, seal position, tunnel finish, cooling, repeatability, safety guarding, operator access and basic maintenance points should be checked.
Useful next step: Send product dimensions, photos, film details and target output through the existing enquiry form so Lancing can check the L-sealer route before quotation.
LU-SPL6 evidence
Questions to answer before treating LU-SPL6 data as a project specification
The LU-SPL6 figures on this page are useful screening information. A project decision still needs product-specific evidence showing that the pack can be detected, sealed, transferred, shrunk and cooled under the intended production conditions.
What should a LU-SPL6 sample trial prove beyond cycle speed?
Direct answer: A LU-SPL6 trial should prove repeatable product detection, film tracking, seal continuity, tunnel finish, discharge stability and acceptable product condition.
The trial should include the difficult products, not only the easiest carton. It should also record the film used, spacing method, relevant settings and good-pack criteria so the result can be understood and repeated.
How should the listed maximum pack envelope be interpreted?
Direct answer: The listed envelope is a screening limit, not a guarantee that every shape within it will run or produce the required finish.
Real clearance is affected by pack orientation, height, protrusions, film movement and the route through the sealing and tunnel sections. The largest product should be shown on a drawing and checked with the intended film before approval.
Which site utilities should be confirmed before approving a LU-SPL6 project?
Direct answer: The project should confirm the electrical supply, compressed-air requirement where applicable, access, floor space, conveyor interface and safe working area stated in the final quotation and machine documentation.
Utility assumptions should not be taken from a generic product page alone. Site conditions, isolators, cable routes, ventilation, floor loading and upstream or downstream equipment may change the installation plan.
What product variations should be included in LU-SPL6 testing?
Direct answer: Testing should include the largest, smallest, lightest, heaviest and least stable packs that the machine is expected to run.
Where products vary in surface coating, temperature, sharpness, barcode position or internal movement, those differences should also be represented. A narrow sample set can approve a setting that does not reflect the real production range.

LU-SPL6 confirmation
Evidence needed before treating LU-SPL6 as the correct route
Direct answer: The LU-SPL6 route should be confirmed against the real product, film and site conditions before purchase. The listed 15–30 bag/min range and POF/PE film compatibility are useful shortlist data, but final suitability depends on pack size, film thickness, sealing response, tunnel recovery, cooling and line handling.
| LU-SPL6 item | Confirmation required | Reason |
|---|---|---|
| Pack size | Largest and least stable products, including presentation face and tolerance. | Protects against specifying around only the easiest sample. |
| Film | POF or PE grade, centre-fold width, thickness, perforation and roll handling. | Controls seal location, tunnel recovery and finished appearance. |
| Output | Target packs per minute and whether the feed is manual, conveyor or upstream equipment. | Practical output depends on stable presentation and spacing. |
| Site | Utilities, floor space, access, heat management and discharge handling. | Determines whether the machine can be operated, maintained and cooled correctly. |

LU-SPL6 checks
Extra checks before shortlisting the LU-SPL6 route
Direct answer: The LU-SPL6 route should be reviewed against real product size, film type, air evacuation, seal method, tunnel recovery and site access. The listed speed and film compatibility are useful starting points, but final suitability depends on samples, layout and the finished-pack standard.
- Confirm whether trapped air needs film perforation or a different pack orientation.
- Check whether the seal edge must be retail-clean, transit-robust or hidden from the main display face.
- Plan safe access for film loading, fault recovery, cleaning and maintenance.
- Record how warm packs will be cooled before handling, labelling, coding or case packing.
