Combining ease of operation and short change-over
times ensures efficient and profitable operation of the tuber. All settings
are made from outside the machine, with the machine running and with no parts
needing to be changed. The HSF can also be integrated with existing production
machines (e.g. printing presses). To this end,
the rewind unit of the machine
is moved by a few feet to position
the HSF module between it and the printing
machine.
The HSF system is typically made up of the following components:
- Unwind for the flat film web (available in various sizes
and with various automation levels)
- Optional printer (stack or C.I. with the required number
of colors)
- Embosser / vent hole perforator as an option
- HSF tube former
- Rewind (various winders of the FILMATIC
 range
are available)
The production of FFS film from a flat web provides a number
of advantages
including: Increased efficiency of the extrusion process, especially when
it comes to small sack dimensions, improved film strength through higher
blow-up ratios, no risk of damage to the folded edges, since the film is
guided on an air cushion while gusseting takes place. In this way film thickness
can be reduced by up to 20% without sacrificing any of the physical strength
of the sack. The result is a notably increased saving potential. In addition
to the standard material for heavy-duty
industrial sacks, the HSF also lends
itself to the processing of
high quality laminated materials such as for
pet food as well as animal feed packaging applications.
