Heat shrink tunnel

Heat shrink and hot air tunnel. Attractive line, compact and accessible, functional and energy saving. The shrinkage furnaces retract the plastic film around the product, adapting the film to the shapes and dimensions of the product. New technical solutions reduce consumption to the minimum, thanks to excellent use of the ventilation and hot air recirculation system and production, in our range of packaging and flowpack machines, with increasingly tight packaging, sticking to the product.

Based on the mounted optionals, they can heat shrink various types of film, not only polyolefin, including PE also with elevated thickness and heat shrinking barrier film.
Electric box on view for immediate error or fault diagnostics, without having to dismantle parts.
As for all the packaging machines, the heat shrinkage furnaces are available in a stainless steel or stainless steel-aluminium version.
The shrinkage tunnel can be equipped with various types of conveyor belts based on the type of film and product: with rollers, Teflon-coated mesh, metal mesh, plastic mesh, etc…
Other than the Single or Double Chamber Tunnel, versions are available with additional chambers (e.g. triple chambers) for high speed, very long products or very thick film, which require longer heat shrinking time.
In the "Combo" version with the tunnel built-into the packaging machines with STAR EVO side sealing, the temperature and air are adjustable using a touch screen.
Heating shrinking tunnel
General featuresComplete recycling of hot air shrinkage chamber. Adjustable air flow and speed. Digital temperature control. Automatic switch off when the temperature goes below 80 degrees. Transport on rotating or fixed silicone-covered rollers based on the film and the product you are working on. Thermal protector against sudden changes in current. Can be used with all heat shrinking films, PE with the addition of Teflon-covered belt. For high speeds or very long products, versions are available with an additional chamber.
Specific featuresThe heat shrink tunnels were designed to solve shrinkage problems of various sized products, up to 3000 mm long and 600 mm high and can be used with all the heat shrinking films available on the market. They can be placed alongside all packaging, flowpack and sleeve wrapper bundler machines, of which they maintain the same shape, or fastened to the packaging machines in the COMBO versions, thereby guaranteeing an elegant, orderly and compact line.

In the COMBO versions of our FLO L sealer, the heat shrinkage chamber of the tunnels can move horizontally thanks to the front handles to align the products arriving from the packaging machine and always obtain the best heat shrinkage, without any need to move the entire tunnel. Optional no longer necessary in the "EVO" version where the product always travels in the centre.
Comfortable command panel with simple temperature speed adjustments and air flow or available in versions with touch screen adjustments.
Air flow adjustment with inverter, independent (one per chamber).
Teflon-covered rollers that also rotate on themselves, avoiding leaving marks on the bottom of the pack
Flaps that open and adjust for improved ventilation and, as a result, better heat shrinkage, adjustable from outside.
Easy replacement of the resistors, excellent accessibility to the chamber.
Optionals available: Straightener for multipack alignment.
Standard heat shrinkage system with resistors or special with Leister. Perfect for printed film since deformation is avoided of the film print.
Conveyor belt with Teflon metal mesh or rollers, according to the size of the tunnel and the type of film.
