L Sealer Machines for shrink wrapping lines
Automatic L-sealers and shrink tunnels specified for your pack size, film and output.
Built for shrink wrapping projects
L-sealer machinery for cartons, grouped packs and presentation shrink wrapping
L Sealer Machines UK is a focused Lancing UK microsite for buyers comparing semi-automatic, automatic and integrated L-sealer routes. It explains how an L-sealer fits with a heat tunnel, what information is needed for a quotation, and how to shortlist machinery around real product dimensions rather than a generic brochure description.
The featured LU-SPL6 route combines automatic sealing with a shrink tunnel for POF and PE film applications. It is aimed at production teams that need cleaner pack presentation, more stable throughput and practical support with line layout.
Machine route
What the L-sealer system includes
The route is specified around the product, film, seal quality and heat-shrink finish required from your line.
L-shaped sealing
The seal stage creates the loose shrink-film bag around the product, with the seal quality dependent on film type, temperature and product handling.
Heat shrink tunnel
The tunnel applies controlled heat to tighten the film and create the finished pack presentation before outfeed or end-of-line packing.
Featured model
LU-SPL6 automatic L-sealer and heat tunnel configuration
This configuration supports automatic shrink wrapping with side sealing and heat shrinking in one line. It is suited to boxes, books, cartons, electronics, retail packs and similar products where the seal and shrink finish need to be controlled.
- Packaging speed listed at 15–30 bag/min depending on product and pack format.
- Applicable shrink film: POF / PE.
- Maximum package size listed as W+H ≤ 700mm, L+H ≤ 800mm, H ≤ 150mm.
- UK advice on specification, installation planning, spares and aftercare.
Applications
Where L-sealer machines are commonly used
L-sealers are typically considered where a product or grouped pack needs a tidy, enclosed shrink wrap rather than only a transit sleeve. They can support food, print, cosmetics, household goods, industrial products and contract packing projects.

Quick answers
L-sealer machinery FAQs
What is an L sealer machine?
An L sealer machine wraps a product in shrink film and seals the film on two sides in an L-shaped seal before the pack moves to the shrink stage.
What pack formats are suitable for L-sealer machinery?
L-sealers are commonly used for cartons, trays, boxes, printed packs, retail packs and grouped products where a neat shrink finish is required.
Can Lancing UK help choose the correct shrink wrapping route?
Yes. The team can review pack dimensions, film type, output target, utilities and line layout before recommending a suitable L-sealer, heat tunnel or wider shrink wrapping system.
