Laser systems for Easy Ventilation
applications
Depending on the production volume
and the task at hand, ROFIN offers systems with
beam splitters and up to four focusing heads for
perforation in web direction, or polygon mirror
optics that provide up to 16 perforation lines
and can deal with very high web speeds. Optimal
climate management can be achieved through holes
varying from 60 to 300 µm in diameter, arranged
in regular patterns or in clusters and even sychronized
to the print on the packaging. Distances between
holes can be adjusted from 4 to 500 mm even within
the same line. Perforation is also suitable for
pressure exchange function, like in packages for
microwave meals. With strong packaging materials
such as PE/PE combinations, Laser Perforation can
even create perforation lines with 5 to 50 holes/cm
for easytear- off applications. |

StarScribe Easy P
A 100 W compact turnkey CO2 laser system
that can easily be integrated into existing production lines
and winding systems. The flexible, articulated arm allows
fast beam positioning with minimal additional effort. With
one, two or four processing heads, StarScribe Easy lasers
are a costeffective solution that yields excellent results.
Used for perforating
a lower density of holes at low to medium winding speeds.
Holes can
be synchronized to the print or continuous. |

StarScribe Easy Remote
If higher laser power is required (e.g. for higher production
speed) ROFIN offers the StarScribe Easy Remote S/P with 100,
200 or 300 W. |

Perfolas Film
Used for perforating packaging films, mostly applied for
Easy Ventilation, but also for Easy Tear-off. High quality
even at web speeds of up to 600 m/min is guaranteed by
very short but high energy pulses. With a maximum web width
of 1100 mm
and up to 16 parallel perforation lines in web direction, the
system is particularly
suitable for high-volume production lines. |
