Manual L-sealers

Manual L-sealers are technological upgrading of chamber machines and enable higher packaging speeds. These machines enable classical film sealing and shrinking as well as only seal products without shrinking the film (e.g. for paper products).

Common characteristics

  • electronically controlled sealing time;
  • PTFE sealing support designed to last two times longer for reduced costs of maintenance;
  • easy replacement of sealing wire reduces time and costs of regular maintenance;
  • frequency controlled speed adjustment of transporting conveyor for optimal packaging of different types of products;
  • compact castors for easy positioning of the machine within production location;
  • energy efficient shrink tunnel with adjustable flaps for control of hot air currents and an accurate temperature setting provides high quality shrinking process – even for products of irregular shapes;
  • easy and quick change of film reels.


With model KKT-450/600 sealing bar has to be held down manually throughout the entire cycle of sealing (sound signal indicates end of sealing cycle), product than has to be pushed on the transport conveyor that takes it to the shrink tunnel.

With models KKP-450 and KKP-650 sealing bar only has to be pressed down. Electro-magnet holders then keep it pressed down until sealing is performed. Product is next automatically transferred forward.
