Heat shrink tunnel
The DM Pack hot-air shrink tunnels are ideal for shrinking plastic film around the product, adapting to both its shape and size, thanks to the complete hot air-recirculating shrinking chamber. Our focus on the search for advanced technical solutions allows us to guarantee reduced energy consumption and the production of ever tighter, form-fitting packaging.
General characteristics
Our shrink tunnels are equipped with adjustable airflow and digital temperature control, with an automatic shut-off function whenever the temperature drops below 80 degrees. The transport is performed by rotating or fixed silicone-covered rollers, depending on the film and product being processed. Our shrink tunnels can be used with all commercially available shrink films, including PE with a Teflon-coated mat. For high speeds or extra-long products, versions with an additional chamber are available.
Specific characteristics
The shrink tunnels have been designed to solve shrinking problems for various-sized products: up to 3000 mm in length and 600 mm in height. They can be installed alongside all packaging machines, flowpacks and shrink-wrappers, which retain their shape, or mounted to the packaging machines themselves, as a COMBO version, to ensure an elegant, neat and compact line.

Details shrink tunnel
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.
