Material for a translucent clear plastic multi layer panel

[TobyR]

Hi there!

I´m trying to render a multi layer clear plastic panel at the moment, but it is really hard to getting it realitistic.
I have tried it with a normal glas material with some modifications, but the reflections inside are getting black cause of the many crossed thin layers.
Have somebody some tips for me?

How about using a thin material with some roughness and clearcoat?
