As Dmitry mentioned, yes, I have seen instances where cards are misplaced inside the slabs, causing them to slide around or get pinched and damaged.

The main reason for my question is grading is still relatively new, all things considered, and I've never heard of any of the companies stating what their slabs are made of, or what technology is used to insure the ultimate protection beyond the obvious holder. I don't know exactly when the first "slab" came around, but say we're in year 20. What if by year 30, we find out the plastics are corrosive? It could be too late for some cards.
