Low Migration
Migration is the movement of substances from the packaging into the filling material. Migration can be significantly reduced with nitrogen inertisation and a coordinated printing process.
The proportion of photo initiators can be significantly reduced. At the same time, a higher double bond turnover is achieved with a lower UV dose.
With curing under nitrogen, the typical UV odour disappears almost completely.
Printing speeds of up to 450 m/min with a residual oxygen content of 50 ppm are possible.
For special applications such as silicones, the residual oxygen content can even be reduced below 50 ppm.
Examples of use:
- Foils (PP/PET/PE/PVC)
- Paper
- Cardboard
- Aluminium
- PVC flooring
- Cigarette packaging
