L-Sealer Shrink Wrapping Systems
Complete Semi-Automatic L-Sealer and Heat Tunnel Systems for Consistent, Professional Shrink Packs
These industrial systems combine motor-driven L-sealing and a matched shrink tunnel on one compact chassis. The operator positions the product in centre-folded film, the L-bar seals and cuts the pack, and the conveyor transfers it directly through the tunnel for a tight, consistent finish. Two sizes cover products from compact retail packs to larger multipacks.

Why Choose an Integrated L-Sealer and Heat Tunnel?
One Complete Shrink-Wrapping Process — Sealing and shrinking happen in a single, continuous workflow, removing the need to match separate machines or manually transfer packs between them.
Compact, Practical Layout — Mounting the L-sealer and tunnel on one mobile chassis reduces floor-space requirements and keeps operating controls, film and product flow together.
Consistent Pack Presentation — Adjustable sealing, conveyor speed and tunnel temperature help produce clean seals and a controlled shrink finish across changing products and film gauges.
Flexible for Varied Product Runs — Adjustable product support, conveyor height and operating parameters suit short and medium production runs with regular size changes.

These combination systems suit operations needing flexible semi-automatic shrink wrapping, regular product changeovers and a consistent presentation finish.
Frequently Asked Questions
For a finished shrink-wrapped pack, yes. The L-sealer encloses and seals the product in film; the heat tunnel then shrinks the film tightly around it. For most new installations we recommend a matched combination system.
Yes, but a sealing-only machine is mainly intended for operations that already have a compatible tunnel or need integration into an existing line.
The 58/44 combination handles products up to 250 × 450 × 150mm, while the 80/65 combination handles products up to 450 × 650 × 150mm.
Maximum output is typically 10–15 packs per minute. Actual throughput depends on product size, film, operator loading and tunnel settings.
No. The sealing bar is motor driven, simplifying installation where compressed air is unavailable.
Consider full automation where volumes are consistently high, products arrive on an existing conveyor or reducing operator handling is a priority.
