COLINES
launches cast MOPE film
Result achieved thanks to joint efforts with DOW and
COMEXI
The
production of Mono Oriented PE film (MOPE) with cast technology is no longer a
“utopia”: the three companies have set a new benchmark for the market,
by producing a very high-level 30 micron MOPE with unique and specific
mechanical and optical features.
The film was totally made
with DOW PE-based resins and extruded on the latest generation of COLINES Polycast
line, equipped with our patented MDO system. The film was subsequently printed
with a high quality solvent-free Comexi Offset CI press, and the result is of
the highest level.
“Mono
oriented PE film is commonly produced with blown extrusion technology – says Nicola
Lombardini, COLINES’ R&D Manager –
but the extruded film has some limits. For instance, the blown MOPE film
doesn’t have good haze & gloss, which is something easily achieved with
cast extrusion technology. In addition, also the possibility to have one side
of the film with good sealability is another enormous advantage of cast
technology. Of course, this opens a huge market for cast MOPE film, since it
would be able to replace some existing products like BOPET, guaranteeing both
higher reciclability and extreme downgauging”.
“We
have achieved something extremely innovative, and we will soon make further
steps forward – says COLINES’ CEO, Anthony Michael Caprioli –
thanks to our brand new Polycast R&D-line. The line is perfectly optimized for
processing PE resins as well and equipped with our latest MDO unit. We have
scheduled further tests with DOW and COMEXI and we are also available for
running tests with our customers. Our goal is to take our customers to the
“next level” of Mono Oriented PE film production”.
“Dow
is committed to developing and providing solutions to enable and accelerate the
move to sustainable packaging designs based on mono-PE structures to advance
the plastics circular economy,” said Jaroslaw
Jelinek, Global Marketing Leader for oriented polyethylene technologies at Dow
Packaging & Specialty Plastics. “We are very pleased
with the outcome achieved together with COLINES and COMEXI on the MOPE cast
technology, and the results prove that we applied the right structure design
with our high performance resins”.
“The
Comexi Offset CI is a sustainable, solvent-free technology, which provides the
highest printing quality with fast time to market and competitive costs”,
affirms Felip Ferrer, brand manager and business development manager of the
offset printing business unit at Comexi. “This
technology uses curing ElectronBeam (EB) inks and coatings, consumes less ink
and energy, has no solvent emissions, and is capable to of printing a wide
range of substrates”. Ferrer emphasize that “EB
curing provides the best solution for recyclable packaging: the partial
crosslink process will increase the thermal resistance of the external
packaging layer when printing PE reverse; and the coating EB will provide high
surface protection when printing on the surface”.
