3.9.2 Film punch
The film punch (see fig. 3.17) separates the film in the across machine direction. It is used for
packages with straight cuts, round corners, round holes and “Euro holes”.
The punch is suitable for any kind of film or combination (such as rigid films, multilayer
aluminum films and flexible films).
The basic top part is intended for use with vario cutting tools, this means that the same top part
can be used for different package widths.
Vario cutting tools can be changed quickly.
After each cutting tool change there is no need to readjust the punch every time.

Method of operation
The cutting table with pressure bar which runs up and down in the punch bottom is pushed up
against the interchangeable blade holder in the punch top. A rugged lever system, which locks
automatically when the cutting table reaches its highest point, guarantees high and uniform
cutting pressure.
The top part is attached to the supports with their fine pitched thread; this makes it possible to
adjust the cutting tools precisely. The result is optimum cutting quality and tool life.
The film waste is collected in the film waste container on the punch top.
