I use these Pill Pouches, found at CVS or Walgreens:

They are heavy duty and have a good zip lock.Works for my FAKs and carying meds in my work/travel.

I scan and print the labels and tuck the copy in the bags so security can see easily what each bag holds.

For a heavier duty approach I've used bison tubes:
