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!
