https://owlcation.com/stem/How-plas...lly-recycled The easiest way to identify between broad groups of plastic is by establishing whether they float or sink. While there are exceptions, the polyolefins generally float in water and the rest, generally sink. The polyolefins include numbers 2, 4 and 5 above - High Density Polyethylene (2), Low Density Polyethylene (4) and Polypropylene (5). So as a rule of thumb, if a piece of the plastic floats, it will be one of these and otherwise, it will something else. cut a small piece and place in water; if it floats not PVC if sinks move to burn test cut a small piece. in a fire safe location, set on fire. A yellow flame with a green tip on contact shows PVC (Polyvinyl Choride), Warning: you suspect the plastic is PVC, do not smell the smoke.

Since I know a good bit of Spanish, I know it's meant to say PVC FREE SHEETS. It's just that translate puts it as FREE SHEET PVC. Spanish says things backward.

Ah, technology is great when it works. That's a good sign about its makeup, though.

I agree, it seems to say it is free of PVC.

Question: my grandpa had some coins in a book. I'm guessing the sheets are the old kind of vinyl/plastic and have PVC just because they have to be pre-1990's.
I just put all the coins in modern flips and back in the sheets, because mom wants the collection to be kept as close as possible to the way grandpa had it. I had assumed that as long as the sheets weren't touching the coins it shouldn't be a problem. Am I wrong?

Thanks. I am thinking about taking them to my favorite dealer to see if he thinks I should give them an acetone bath just to be safe. I've heard all about the greenish tint, but I don't think my eyes are that attuned to such things, because in the videos I've watched, where they act like you ought to see the green, I just see silver. None of the coins in this book are high grade or key years (grandpa's house was robbed and the thieves got the books he kept in his desk--all we found was the mostly junk silver and this book, which he'd kept in a cranny upstairs). But they do have sentimental value so I want to take care of them.
