These film chips are made up of several flexible layers and are manufactured foil connections in which microchannels are processed. Components such as pumps and valves can be directly attached to the chip, which remains flexible. The film can be tempered very easily on the one hand and on the other hand it can be used in unusual forms.
The materials available for the film layers are:
- Chemically-inert polyimides (PI)
- COC (cyclic olefin copolymer)
- Polyethylene naphthalate (PEN)
