Reply to "Tips on Achieving a Wet/Glossy Liquid Look (Which Doesn't Remain Tacky)?"

It sounds like you've tried all the obvious ways except for corn syrup or glucose, which will also remain tacky in humid conditions. Why not package the cookies another way - i.e., put them in small boxes and then bag them? The box would prevent the bag from sticking to the cookie, but then the cookie would still be well-sealed if you feel you need to seal it that well.
