bubbles in game labels

SsPpAaMm

I was going over a few of my games and I noticed that a couple of them have started to get a bubble in the label.  Odd because I normally check for stuff like this.



I noticed a couple gameboy games and a few sega genesis games doing this. 





I keep all of the games in those big rubbermade bins and keep them upstair where it stays pretty dry and room temperature.  I am sure it gets a little colder at night but since we sleep up there it isnt like the heat is totally off. 





I did buy all of these games used and most of them from gamestores in the area.  Any idea on what causes this and what I could be doing wrong?

I had a label bubble because I kept it in my glove box too long. I assume it was the back and forth from hot and cold that did it. I was able to kinda smooth it back out but there's a little crinkle where it didn't sit perfectly flat. I considered putting it back in my car to see if I could get it to bubble again... and flatten it better... but I have too many other projects at the moment to care.



If anybody has a good method for getting small creases out of labels I'm all ears.

Heat the labels to melt the adhesive back out, worst case you could heat it enough to peel it back past the bubbles then just re-lay it down
