Two model sizes, the LT 470 and LT 670, combine a heavy duty L-bar sealer and shrink tunnel for packing, sealing and shrinking products.

They can be used with a variety of films due to their precise temperature and speed controls, according to the manufacturer.

The devices minimise maintenance and eliminate the need for a hot-knife seal bar by incorporating a seal wire temperature control system, providing strong seals and increased life of the wire.

Another key feature, according to the manufacturer, is a convenient scrap drop-and-collection area for trimmed film, which cuts clean-up times, while a single adjustable height control for the product take-away and tunnel conveyors smoothes product transfer.

According to UK agent Friedheim International: “The robust design and use of integrated controls provide improved cost efficiencies due to greater productivity and reduced downtimes as a result of the minimal maintenance needed.”
