I've had portra 400/800 with me on several flights through handluggage and a few x-ray machines. It's rather heavy so i guess there's metal under the plastic surface. It also just appears as a solid block on the x-ray machines but none of the security staff asked me to open and check inside.
No issues whatsoever.
I put rolls in a clear ziplock bags, then in the hand-check tray. It looks like rolls of film. They sometimes open a random box just to check it is what I say it is.
I got one of those things for flying:
