If it smells like a new shower curtain, it's PVC and not safe for coin storage.

Buy SafeFlips, no then don't worry.
They're actually called Saflips and they are made of Mylar and are totally safe for coins.

If the plastic is hard and crinkely (sp?), it's probably OK. If it's soft and pliable, it's likely PVC.
When in doubt, get rid of it, you'll thank yourself later.
Ok, a typo...
I thought all vinyl flips contained PVC?
Mylar flips are the way to go for long-term storage, but they are not as nice to handle.

The flame test (Beilstein- thanks for the link, forgot the name) works well. The smell test is also a good indicator. I just buy Saflips for the last 10-15 years... Threw out all the old PVC ones I had. Cheers, RickO

I guess you should always assume they contain PVC.
my solution is simple: I always have a good supply of non-PVC Archival Flips and when I buy something in a flip I immediately change to one of mine. if I'm concerned enough so I believe the old flip contained PVC, then I would take the appropriate steps to safeguard the coin.
Not only do I do the same thing, I also give the coin an acetone rinse in case there is any unseen PVC plasticizer residue from previous holders.
