Uline.com does custom printing on boxes and mailing bags.

CentralPack.com also does custom printing on different types of mailers:

sure, they will work on bags too. The labels are made of vinyl, and stick to pretty much anything. Depending on what you want it to say, and how many you want, you can get them for as little as $0.17 each.

That actually sounds like it might work for some purposes. So vinyl labels would stick and be flexible on bags (not come off during the shipping process)?

These are done on white vinyl, very flexible, and are as hard to get off, as it is to open one of them plastic shipping bags without perforations!

Thanks for the info and the pictures. That really helps!
