Labels often leave a sticky residue on new items. It takes a lot of scrubbing or special chemicals to get those off. To eliminate this problem the adhesive should evaporate on its own. The label would have a sealing back layer that prevents evaporation, except very slowly at the edges. When the label
is removed the adhesive layer that is exposed to air is huge and it evaporates in a few hours or days.

You would be scared about all the stuff they glue these days, but it often works better than rivets or bolts. [kbecker, Oct 04 2004, last modified Oct 05 2004]

So what is this adhesive made out of? Until you can
describe it, MFD, magic. |
|
| |
A friend just damaged a nice wood carving with solvent because it discolored the wood. The same happened to me at various occasions, and you never know in advance what solvent is safe for a plastic (unless you are the manufacturer). Anyway, why use extra chemicals if you can avoid it? |
|

They can make Cyanacrylate adhesive that is activated by moisture, they can make a DVD that wipes itself (link) so it becomes garbage. It should not be too hard to make something sticky to hold on a label that decomposes to something volatile. We are not talking about a heavy duty adhesive that holds together an airplane. |
|
| |
Airplanes are held together with glue??! |
|
| |
[DN] Yes they are, in particular the rudder flaps. See link for a start on more scary stories. |

[oxen crossing], this is a valid invention idea and so what if [kbecker] doesn't know the exact chemical makeup of the adhesive. Chemicals that lose their adhesive properties as they oxidize seem well within the realm of the possible to me. |
|
| |
Pending further discussion, MFD removed, for now. If
[kbecker] had mentioned //losing adhesive properties as it
oxidizes// I would not have mfd'd in the first place. I think
evaporation of the adhesive, leaving a perfectly clean
original surface is a bit WIBNI, and needs further
description to support it. If the idea described [bristolz]s
oxidizing adhesive, and a method for removing it (seems
unlikely that it would just fall off), then it would seem
more reasonable to me. |

It's an interesting idea. Since
plastics can be made from
cornstarch, and thus be
biodegradeable, perhaps it would
be possible to make glues from
cornstarch. |
|
| |
Suppose that the glue was soluble
in water but the label was made of
biodegradeable plastic to protect
the glue from premature release.
Once you strip the label the glue
dissolves. |

I find that some labels just peel off really easily, others leave a horrible papery mess that needs a lot of work to get off and yet others won't budge unless you pour a gallon of solvent on them. So, why don't "they" make all the labels out of the stuff that peels off easilly. |

3M was doing super-strong
adhesive development when they
invented the adhesive that powers
Post-It notes. The particular
qualities are there: easy to remove
and leaves no residue. Maybe they
could market the adhesive without
the paper... |
