Precise L-bar sealers for cartons, trays and retail packs with clean, consistent seals every cycle.
About the L-Sealing Machines
Model: PK-LSM-450
With a 550 × 450 mm maximum seal size, 20–30 packs per minute and low film wastage on POF, PE or PVC film, an L-sealer is the right first step into shrink packaging for growing MSMEs — and pairs with a Packten shrink tunnel as a semi-automatic shrink wrapping line.
Machines are delivered, installed and supported across India with operator training and a 12-month warranty, direct from our factory.

How the L-Sealing Machines works
Position the pack
Place the product on the sealing bed and lower the L-shaped sealing arm.
Seal & cut
The heated L-bar seals two sides and trims excess film in a single stroke.
Shrink (optional)
Sealed packs pass to a shrink tunnel for a final tight wrap.
Collect
Finished packs are discharged, ready for cartoning or dispatch.
Key benefits of the L-Sealing Machines
Clean, strong seals
Precise L-bar seals with no burn-through, cycle after cycle.
Fast changeovers
Adjustable film width and seal timing handle mixed pack sizes.
Compact footprint
Fits tight production lines without heavy civil work.
What is an L-sealing machine?
An L-sealing machine (L bar sealer) is the simplest reliable way to shrink wrap a product. The operator places the product between two layers of centre-fold film; the L-shaped bar comes down once, sealing and cutting two sides in a single stroke (the fold forms the third). The loosely wrapped pack then passes through a shrink tunnel, where the film tightens into a clean, retail-ready wrap.
What can you pack with an L bar sealer?
- Mono-cartons and boxes — cosmetics, pharma, electronics, stationery
- Trays and multipacks — food trays, bottle and can collations
- Retail packs — books, games, frames, household goods
- Bundles — anything within the 550 × 450 mm maximum seal area
Packten L-sealers run POF, PE and PVC films — the film guide explains which to choose per product.
When is an L-sealer the right machine — and when isn't it?
At up to 20–30 packs per minute, operator-paced, an L-sealer is the right economics for MSMEs and mid-volume lines: low film wastage, compact footprint, single-phase 220 V power, and a price far below full automation. When volumes outgrow the operator, the step up is an automatic web sealer — the comparison in L-sealer vs auto web sealer shows exactly where the crossover sits.
What does an L-sealing machine cost in India?
The quote moves with seal area, build (mild steel powder-coat vs stainless options), film handling features and whether a shrink tunnel is bundled. As a guide to how quotes are built, read what decides shrink wrapping machine price in India — then ask us for an exact price for your pack sizes; L-sealers are typically our fastest machines to deliver (3–5 weeks).
Getting started with shrink packaging
Most customers start with an L-sealer plus shrink tunnel as a semi-automatic line, then automate later as volumes grow — the same film and tunnel carry over. Packten manufactures both machines in Surat, Gujarat, delivers and installs across India, trains your operators and backs the machine with a 12-month warranty and factory spares. Request a quote or see the pair working as part of a turnkey packaging system.
Common questions
Standard L-sealers handle packs up to roughly 550 × 450 mm. For larger products we recommend a custom sealing frame or an auto web sealer — share your dimensions and we will advise.
The L-sealer can be supplied standalone or paired with a matching shrink tunnel as a complete seal-and-shrink line. We size both units together to your throughput.

Yes — it is usually the right first machine. An L-sealer is operator-paced, runs on single-phase 220 V power, has a compact footprint and wastes very little film, so it fits both the budget and the floor of a growing unit.
Packten L-sealers run POF, PE and PVC centre-fold shrink films. POF suits most retail products; PE suits heavier bundles. We help you pick the film during trials.
