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
