ackaging
After an adequate
ageing
period spent in an ageing room, the jumbo rolls are sent to the
slitting area
where
they are slit into multiple finished reels that comply with the
specifications of the client’s order.
When in need
of additional processing, these reels are sent to the secondary slitters, before being moved to the packaging
area and taken to the
finished products warehouse.
M
etallization
It is an
additional process
that may be
required by the
customer.
It takes place on a
high-vacuum system
that
deposits a thin layer of
aluminium
on one of the two surfaces
of the film,
improving its barrier properties.
A re-slitter provides
one or more finished product reels that are then stored in the
finished products warehouse. The
lateral scraps
produced by
the slitters during the metallised reel slitting
are stored
in unit
loads and
destined to external sale.
R
egranulation
Regranulation is a
scraps reprocessing procedure
from which it is possible to obtain the
granule
, which is then
stocked in special silos and will be
reused during the extrusion
process in variable percentages, depending on
the type of product.
The scraps deriving from film break-offs (during the stretching
process or during the start up of the extrusion lines), slitter
scraps, grinding of jumbo rolls or finished product reels that do
not match the standards are
all appropriately grinded
through
mills and/or grinding machines. The material derived from
this process is then
sent to an extrusion system
through which,
by material melting, it is possible to
obtain the granule
thanks
to a specific
regranulation machine.
The granule is then
cooled
in a water tank, dried, weighed and sent
for stocking by a
pneumatic system to the extrusion lines
silos.
