POLYTEX – cost effective multi-purpose tuber
including winder
for the production of one- or two-ply flat and
side gusseted tubes from plastic films, woven fabric and composite
materials with
a speed range up to 150 m/min. Due to its modular
design, the POLYTEX can be tailored to meet most different market and user
requirements.
The POLYTEX is the ideal machine for the production of high
quality tubing
for the entire range of premade and FFS specialty bags. To name but a few
examples: sacks made from stretched films, composite materials, non-wovens,
film and woven fabric laminated to paper and aluminum, or two-ply sacks.
Forming the tube from the flat web allows for special sack constructions
providing seam venting possibility for extremely
dusty products. Add to this,
excellent quality printing is possible
on flat webs only.
As an added benefit, the tube forming process offers a cost reduction potential:
Multi-up production of flat films on wide
blown film lines helps the film
producer exploit economies
of scale. Higher blow-up ratios can be used and
folded edge
damage is avoided permitting film thickness to be reduced
without
compromising film strength. Downstream converting machine efficiency is enhanced
by the narrow tube width tolerances
achieved through the tubing process.
The performance of the
AD CONVERTEX in particular is given a boost since
blocking of tubing caused by strike-through will not occur any longer.
