Reifenhuser cast pet film linesspot landing through high degree of vertical innovationinitially at k 2010 in dsseldorf, reifenhuser presented a cast film line producing 3layer unstretched cast pet film that caused a great stir and attracted internationalinterest. By now, four lines using this technology are in operation worldwide. Furtherlines are scheduled to be shipped shortly.key component of this line is the reitruder twinscrew extruder that allows processing ofpet without the need for precrystallization and predrying, similar to the production ofsheets.
This technology offers the customer many technical advantages in addition to aparticularly costeffective pet film production.once again, reifenhuser cast sheet coating is setting the benchmarks in the area of highqualitycast film lines with superior efficiency.the winders optimized for a demanding range of products are based on a wellprovenconcept.
Thanks to a specially designed rotary arm winder, it is possible to wind bothsensitive 12m thin pet film, classical cpp film, and stiff pet film of 150m thickness in away that eliminates the need for slitting and rewinding for many applications. This allows toimprove the production result and save costs.blister films are one of the many possible applications. The special cast film technologyenables to reduce the thickness of these films to 120m which is considerably below the150m common in polishing stack operations.
That means that cost advantages can beobtained also in this area.pet with pepfrom a technical point of view there is a clear trend towards coextrusion. While in the pastbopet films were often laminated with barrier films it is now possible to coextrude thesestructures in a single operation. This process is already being used successfully on the linesof reifenhuser cast sheet coating who can draw on decades of experience in sheetextrusion.smaller line sizes, compared to those for bopet, combined with lower performance give theproducer much more flexibility.
Small orders for special film thicknesses can be realized aswell as recipe modifications for special applications.michael beckhoff, sales manager of reifenhuser csc says the many possibilities andvariants to produce, for example also cpp film of the same quality and with the sameefficiency as obtained on conventional cpp lines, open up completely new perspectives inthe optimal utilization of a line.
To put it casually pet with new pepthe manufacturer of cast film lines, sheet lines and coating lines who was renamedreifenhuser cast sheet coating on 01.07.2012, strengthens its position in the cast filmarea with this innovative process, and continues working on the consistent furtherdevelopment of these outstanding technologies also in view of k 2013 in dsseldorf
