blown film line

One 27 layers Blown Film Line,
with unlimited film structure
possibilities inspired to the mi-
crolayer technology where it
possible to overlap or alter-
nate different layers to im-
prove the mechanical
characteristics of extruded
films and reduce their final
thickness.
GAP has an advance and futurist R&D center in Trecate
where are installed
Made in Italy innovation

GAP has also a 9 layers multi-bubble extrusion line for barrier
shrink and heat set material.
In our R&D you can see your future film structure
and your idea become reality

HOW IS MADE THE NEW BLOWN FILM LINE?
The blown film line is composed up to
9 extruders and up to 27 micro-layers
die available from 200 to 700 mm, any
solution from monolayer to 27 layers
are available.
Thanks to the special feed block
system is possible to generate
unlimited film formulation alternating
up to 9 different type of raw materials
in sequential mode or alternating way.
This line is complete with automatic
air-cooling ring, most of the new line
control software comes from the
experiences gained on our complex
double bubble line to have higher
performance in the web control.

HOW IS MADE THE NEW BLOWN FILM LINE?
Moving forward GAP’s strategy:
start to reduce film thickness
GAP has already tested several structures on the
new 27-layer microlayer line, both with blocks
and alternating layers. We have achieved very
comforting results in terms of mechanical perfor-
mance of the film that leads to a significant re-
duction in thickness. In fact this line has been
studied to reduce film thickness by increasing
the number of layers. Thanks to the laminar flow
structure GAP has been able to generate better
mechanical performances and lower thickness-
es of material. Mechanical tests have shown a
reduction of around 20 to 25% of the original
thickness.
