ICCS is a very respected grading company of Canadian coinage. The coin is sealed in a non-PVC square of stiff plastic. This plastic is then placed in a nice flexable PVC laden flip. A bit of the worst of both worlds.
Overall is isn't such a bad arrangement. Easy to store and display.
First, the coin is obscured through two layers of non-optical grade plastic. And the outer flip will get progressively funkier, as PVC flips do. Not the best for seeing your coins.
So now you've got a coin encased in a sealed non PVC flip, entombed inside a PVC flip. Some say the coin is safe this way, while others wouldn't store their worst enemy's coins like this. Even assuming the inner flip remains totally intact, and a complete barrier to PVC, it seems like a risky proposition, and many of the darksiders automatically "crack" ICCS slabs on arrival.
Personally, I have had three relatively large and heavy Canadian coins (two dollars, one half) that managed to crack the inner flip, resulting in, essentially, a nice coin sealed in a PVC flip, requiring either
1) Slow boat back to Canada to reslab my now PVC contaminated(?) coin in another one of these precariously designed slabs
2) Liberation! My choice! (of course, with the loss of a respected TPG's evaluation )
PVC has no place in archival storage of coins. It's shameful and an embarrassment that they would even still consider using it
PS: The last time I opened my box of ICCG coins, it was like I just unsealed a crate of shower curtains...the stench was shocking...PVC city!

Didn't PCGS do it that way when they first started? (For an extremely short time?)
Great transactions with oih82w8, JasonGaming, Moose1913.

No, But David Hall's company did prior to the founding of PCGS:
