I still use and travel a lot with film, including ISO800 and ISO3200 film the latter of which is totally destroyed if it goes through the scanner, even in an film protection bag.
Megapixels are unimportant, there is a look to film you can’t reproduce no matter how many VSCO plugins you use :)
To be clear, film protection bags don't work for scanners at all. And if the operator sees a blob he can't image, he is likely to back up the belt and increase the power until he can.
Film protection bags are to protect against fogging from radiation at higher altitudes, not the scanners.
