Extrusion International 1-2018

34 Extrusion International 1/2018 BLOWN FILM „Among other things, the take-off unit plus lay-flat unit but also the winder have been further developed. Depending on the customer’s requirement, with the new line, contact, central or central winding with gap is possible“, says Dr. Friedrich Kastner, CEO Collin. „By means of the comprehensive optimization, nearly per- fect bobbins are realized and thus the further process- ing for our customers is easier and the resulting prod- ucts have a better quality“, explains Kastner. New Blown Film Line with Numerous Innovative Features „Furthermore, the standard speed of 30 m/min has been increased to 50 m/min. If desired, higher speed is possible – in order to approach product speed if neces- sary“, says Corné Verstraten, CSO Collin. Online, the quality of the films is permanently con- trolled via the COFIS Film Inspection System. At Fakuma 2017, Collin presented another new product – the new Collin die, integrated into the blown film line and perhaps a little bit diverted from its intended use. The Collin blown film line presented itself completely updated at the Fakuma 2017 booth.
