BLOWN FILM LINE

MORE LAYERS

LESS THICKNESS

BETTER PERFORMANCE

2

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.
