Industry First 11-Layer Blown Film Line
During the 8 days of the exhibition Hosokawa Alpine is producing complex barrier film structures on its 11-layer blown film line. The 11 extruders are arranged to minimize total footprint and the water cooled main drives are quiet and efficient. Alpine’s patented X-Die has been increased to 11 layers, maintaining the same film quality that customers have come to expect from the X-Die.
The line running at K 2016 has an 11-layer, fully nested spiral die. That consists of 11 cylinders inside each other, each one precisely machined with channels and spirals for a specific layer of the film, taking the melt from the extruders. The spiral die allows all the extruders to be on the same level. Hosokawa Alpine is running different variations of materials during the show, depending on the day. Every day, the line is running an EVOH barrier layer in the center, sandwiched between two layers of nylon and two tie layers. That gives the company three layers on each side to change around. The 11-layer blown film line uses resins from ExxonMobil Chemical, The DOW Chemical Company, and Total Petrochemicals & Refining SA/NV.
Alpine’s cooling systems ensure the highest possible output rates with maximum bubble stability. The total film thickness and individual barrier layers are measured and displayed by an NDC inline scanner. The line is equipped with Alpine's newest oscillating haul-off design with integrated annealing, specially designed for barrier films and manufactured att heir subsidiary Hosokawa Kolb near Cologne, Germany.
Line Control is provided by the new ExVis 4.0 with our “One-Touch” Change System. ExVis 4.0 is operator friendly and includes full energy monitoring. As with all Alpine ExVis systems remote on-line support is available for quick equipment maintenance and trouble-shooting. Alpine’s latest Winder with reverse wind capability and a smart roll handling system facilitates smooth roll and shaft changes.
