Do any of these allow for making your own size, like a laminating machine does, or do you need the bags to be pre-sealed on 3 sides? Specifically, I'm thinking of IFAKs which would be pocket size, or 3"x5".
That's what I'm looking for too. Would like to see more details on that capability. I don't have a whole lot of use for only being able to package things in an 8"x10" form factor.
