How well does that stuff work for longer term storage? As in you seal some pills with it, toss the package into your FAK, and carry it around for a few days. Does the seal hold, or does movement/vibration/whatever losen it up???

My wonder as well, although since I usually leave my bag packed for a long time (couple months at a time between rotations and repacks), loss of sticky is as big a concern to me as residue is.

The Press N' Seal is very tear-resistant and seems great for long-term storage. I have some old pills that I needed and teared the package open and trust me, it's great! The product doesn't leave any sticky residue either, the coating of the pills seem unaffected.

Try it! ;-)
