Where to buy milky diffusion film?

[brush1]

I need to do manu for for new owner of very old restaurant.
It is empty light box now. I will print on backlit material and I need milky diffiusion film for the back and clear film for the front (backlit will be sandwiched between). I don't have any clue how it call.
Slide space is 0.25". It need to be fexible (no side opennig possible) so acrylic/plexiglass is not going to work.
Please help.
Thank you

White styrene perhaps? Can get as thin as 0.010".

Nope.
It is not that translucent.
I need clear front cover material to. It is I think some sort of polycarbonate plastic.
Thak you for trying.
