What is an L-Sealer?
An L-sealer is a piece of packaging equipment designed to enclose a product with shrink film. Commonly, an L-sealer consists of an adjustable product tray where the product is placed and the top layer of centre folded film covers the product. Next, the product is moved to the sealing area with a seal head and takeaway conveyor. The seal head is shaped like the letter “L” and uses heat to seal the film together, creating a loose bag around the product being sealed.
Manual and automatic L-sealers are used to wrap products and can be paired with a shrink tunnel to shrink the film around the product. Often, the L-sealer is a separate piece of equipment from the tunnel; however, combo unit L-sealers combine an L-sealer with a shrink tunnel on a common frame for a convenient all-in-one sealing solution
The L-sealing machine is a particular kind of bag sealer which uses a thermoplastic film folded lengthways. The product is placed between the two halves of the film before the L-shaped sealing bar encloses the pack, which is sealed on three sides. An L-sealing machine is often used along with a shrink tunnel.
