A key component of this line is the "Reitruder" twin-screw extruder that allows processing of PET without the need for pre-crystallization and pre-drying, similar to the production of sheets. This technology offers the customer many technical advantages in addition to a cost-effective PET film production.
winders optimized for a demanding range of products are based on a well-proven concept.
Thanks to a specially designed rotary arm winder, it is possible to wind both sensitive
12μm thin PET film, classical CPP film, and stiff PET film of 150μm thickness
in a way that eliminates the need for slitting and rewinding for many
films are one of the many possible applications. This special cast-film
technology enables reduction in the thickness of these films from the usual 150μm
to 120μm in polishing stack operations. That means that cost advantages can be obtained
also in this area.
a technical point of view there is a clear trend towards coextrusion. While in
films were often laminated with barrier films, it is now possible to coextrude
these structures in a single operation.
line sizes, compared to those for BOPET, combined with lower performance give
the producer much more flexibility. Small orders for special film thicknesses
can be realized as well as recipe modifications for special applications.
Beckhoff, sales manager of Reifenhäuser CSC says, "The many possibilities
and variants to produce, for example also CPP film of the same quality and with
the same efficiency as obtained on conventional CPP lines, open up completely
new perspectives in the optimal utilization of a line. To put it casually: PET
with new pep!"
