Sorry. I don't have any experience with the plastic cans. If you're really concerned, perhaps you could stow the film in some kind of metal box? A coffee can would be quite a bit heavier metal than that used for 35mm canisters. I guess it depends on how much film you're planning to carry though.

Alternatively, you could send all your film ahead of you via Fed-Ex. They will not x-ray that which is declared as film (or, so they say). There are a bunch of us living here in the SF Bay area. I am sure any of us would be happy to receive you film. I don't get into the city very often but, am happy to help in this fashion if you wish....send me a PM if that is what you want to do.
