Düsseldorf, Germany — The new seven-layer blown film line displayed at K 2019 by extrusion machinery manufacturer Bandera has been designed to offer customers the highest possible degree of flexibility, said Andrea Rigliano, general sales and marketing director at the company.
Called the Barrier Flex Seven, it can run both barrier and high-barrier blown film, as well as polyolefin film. The flexibility of the new line does not affect either hourly output performance, in the case of polyolefin film production, or end-product quality level with unrivaled tolerance ranges when producing barrier film.
The company introduced the line for the first time at K in Dusseldorf.
"Compared to the previous version, we've made a number of modifications, including adding a brand-new Human Machinery Interface," Rigliano said. The new line control system maximizes the communication with industrial equipment and systems for data collection and monitoring, simplifying processes, reducing mistakes and optimizing time.
"That is one of the top characteristics of this innovative line," he added. Remote control technology makes it possible to connect using a tablet or smartphone for simplified diagnostics, for driver and motor predictive maintenance and increased process-control parameter accessibility.
"What's also is we designed a die that, even though it is a seven-layer one, can run three, five or seven layer polyolefin-dedicated formulations. Moreover, it can be adapted to barrier film with EVOH and polyamide," Rigliano said.
Other modifications included the addition of low-energy drivers and ABB SynRM2 reluctance motor systems for synchronized operation. This results in lower noise emissions and considerably simplified maintenance requirements. As the operational temperatures are lower, cooling servo fans become unnecessary, which increases reliability and continuity of operation.
The line also features Bandera's new winder. The ESR winder series is now available with a torque motor, which allows it to run at a higher speed for more efficient production.
