Reactivating Label Adhesive?

03/15/2008 3:10 AM

All,

I have some old labels that have lost their "stickiness" so to speak. I need a way to "reactivate" the adhesive currently on there without adding anything new to make it stick to what is basically thick tinfoil. Something that would quickly heat the adhesive behind the label maybe? One stipulation is that it can't be another adhesive or a form of liquid; it would have to be something that reactivated it externally in a sense. I'm not sure of the composition of the adhesive so I don't know if maybe there was a chemical change over time that caused the lost adhesiveness. Anyone ever hear of using something like a blue UV light to do this? Any other ideas? Thanks for your time!

a lot of labels can be made a little stickier with a sprayed touch of the right solvent to the back just prior to use, one at a time. There is no way to do this to whole rolls.

find out from label makers how to extend the life. often a sealed moisture proff bag in a freezer will help the life

You need to know which solvent which when applied to your label will make it sticky.

Then set a container up with two sections open at the top of the separator, put labels in one side and solvent in the other,labels obviously not sitting on each other put the lid on and leave as long as required for the adhesive base to re-absorb the evaporative part of the solvent.

Toluene is a good starting solvent.

I use acetone a lot to reuse adhesive backed products. It all depends on the solvent used in the first place.

I have had much success with average adhesive backed products, as long as there is enough residue left.

You probably don't need heat at all, and the solvent will clean and dissolve enough adhesive to use.

Depending upon what you want to stick them to, just put some new glue on them. Super glue works for most surfaces I have found.....and its cheap...
