This has cardboard sides and a very thin plastic film.  And also, are these kind of flips safe? These are thicker plastic. They have a pocket in both sides. No name brand. Bought 50 for $6.99

The 2x2 should be okay EXCEPT get the size that fits the coin. The coin slides around and that results in wear.
On the other hand the flip appears to be the "soft" type which generally means PVC.

The 2x2 cardboard holder is fine, that's the most commonly used type of coin holder by numismatists. However, using the right size holder for the coin is important. Coins look better in their right size holder, and it prevents them from silding around and getting worn/hairlines.

I work with PVC daily in a lab.
Lots of safe soft clear materials out there that aren't PVC.
To test for PVC, do this.
Cut a piece and put it in water. Make sure there aren't any air bubbles making it float. If it floats, it is not PVC for certain. All PVC sinks in water.
If it sinks, it may or may not be PVC.
Burn the plastic (do this outside and not near Smokey The Bear). Should have a green tint to the flame indicating the chlorine. If it does it is PVC.

BuckeyeCoinGu, that is some great info! Thank you so much, I'm trying this. Good to get rid of that little nagging thought about "what if they really are PVC"?

I like using slightly oversized cardboard 2x2 because I can see the edge detail on certain coins. If you staple them good and tight, there is no sliding around, although there is perhaps more potential for getting dings in your coins if you aren't careful. Although I usually wouldn't go quite as oversized as the above.

Oversized holders (sometimes even correctly sized holders) may cause the coin to move and can even cut the foil allowing the coin to fall out of the holder. The plastic flips unless sealed somehow can easily allow the coin to fall out. And I really dislike staples in any type of holder as they can easily contribute to scratches.
If the coin has any real value, I suggest using what are referred to as air-tight holders. Since PVC is used a a platicizer, and the air-tights are hard plastic, there would be no reason to use PVC in the manufacture of these.
Hope this helps.

Generally speaking all 2x2 fold over cardboard fills are using mylar film and it does NOT contain PVC. So yes they are safe for coins, the real problem with them is they wear out over time if a lot of flips are tightly compressed in a box, they can tear, they use staples (which can rust) or scratch other flips in storage. Other than that the 2x2 cardboard holders are what I use the most.

I use those for special coins I like to examine closely from time to time...and I can slip written or typed notes in the second pocket....I don't have to deal with staples. And they fit nicely in 2x2 albums too.

One size for Nickels and Quarters. One size for Half Dollars and Dollars. For dealers much easier and less inventory. People always say not a good idea due to allowing coins to move. I never could figure out why anyone would shake or do anything to make the coin move anyway. Once in a holder for the flip, in a box, etc., who is shaking them anyway.

I have zero movement when using one size up, no matter how much I shake it.  The coin is still tight, just some extra room between the edge of the coin and the edge of the hole. I think it looks nicer.

So jbuck, you must be stapling them pretty tight. Do you get lots of torn or busted cardboard because of that?

I staple them half-way between the edge of the hole and the edge of the holder. I also use four staples, not three.
The only problem I ever have is when my stapler malfunctions and one or both sides of the staple do not penetrate.
