FILM LINE FOR PRODUCT DEVELOPMENT

Dimensions
The figure to the left shows a blown film line.
Decreased height of the 3 extruders ensures optimum
cooling length. The 3-layer coextrusion die (expandable
to 5-layers) allows the production of multi-layer film
with very narrow tolerances of individual layer thickness
and the overall thickness.
A mono or dual-lip cooling ring guarantees a high
cooling performance while the frost line can be
adjusted precisely. For optimisation of the start-up
procedures, the take-off can be adjusted in height
by a motor.
The layflat width can be controlled, which allows the
production of a reliable and constantly high product
quality level with low personnel requirements.
