Hi everyone I got a base set blister in mint condition and the bottom has separated from the cardboard. I don’t intend to sell any time soon but I thought about re-gluing the bottom just to prevent any more damage/separation. I’m sure it’d only take a tiny drop or two of super glue. What are the risks in doing this? Will it give it an ugly re-sealed looking appearance?
Don´t do it, it will be way harder to sell it than just leaving it.

Don’t reglue it. This is an inevitable part of collecting old blister packs. Regluing it would make it inauthentic, in a way, and lower the market value. If you store it correctly, you should be able to mostly preserve its current state.

Obviously reglue is not a great idea but curious how you preserve blisters I have a few that have very minor separation nothing major as of yet but also know if it say got bad enough that the pack could be slipped out or switched wouldn’t that be just as worthless to a potential buyer?
Seems like if the glue separation issue is common that all blister collections are just ticking time bombs to lose packs
I don’t think there is a way, it’s caused by the glue drying and losing its stickiness. Based on the limited knowledge on solvents I have, I know somethings just don’t stay stuck with certain materials, the plastic being the issue in this case. Unless there’s a product that can rejuvenate the glues bond, there’s nothing that can be done.
I do keep mine stored flat. I’m not sure if this is helping or not but in theory the bond can hold better with less gravity effecting it.
I’m not a chemist or material scientist, so don’t take my opinion as necessarily correct (and I’d love to hear from someone who knows more about this if I’m wrong), but I would imaginethat the adhesive bond is weakened by heat and/or low levels of air water-vapor content. So I think that the ideal storage of blister packs is in cooler environments with decently high levels of atmospheric water vapor (but obviously not excessively high levels; certainly not in ‘damp’ environments).
Well I was a chemist so to answer the op, no not superglue. A mild adhesive is best. Use your finger and a glue stick, Don’t touch the paper.
Of course only use this method for personal display purposes. In most cases it can be detected.
