PET STRAPPING TAPE
“The ideal system for
all requirements”
Reimotec Maschinen- und Anlagenbau GmbH is expanding its
range of PET strapping tape lines by including the VACUREMA
system from recycling specialist EREMA in its supply range.
Reimotec is the Reifenhäuser Group’s specialist in strapping
tape production lines and one of the most experienced
suppliers in this market segment, with more than 100 lines
delivered for this application since 1977.
In addition to providing its own,
market-tested technology for pro-
ducing highquality strapping tapes,
Reimotec also supplies the extrusion
lines for producing the polymer melt.
Today’s major challenge for this ap-
plication is the ever-increasing share
of recycling material in the resin, usu-
ally consisting of PET bottle flakes, in
parallel to similarly increasing quality
demands that are placed on the end
product – namely the strapping tape.
Previously, lines for PET strapping
tape were equipped exclusively with
single-screw extrusion systems until
Reifenhäuser introduced its twin-
screw technology (Reitruder) in 2001
and initiated an important step in the
market towards the improved pro-
cessing of PET bottle flakes.
Since 2001, approximately three
quarters of the strapping tape lines
supplied worldwide by Reimotec
have been equipped with this twin-
screw technology: a transformation
that is primarily due to the ease of
applying this technology to the pro-
cessing of PET bottle flakes.
A major advantage of the twin-
screw, compared to the single-screw
technology, is its better suitability for
technically demanding recyclates.
However, if the iV value of these raw
materials is too low, the twin-screw
extrusion reaches its limits. In order
to meet the demands for processing
raw materials even with critical iV
values, Reimotec has now linked up
PET bottle flakes
