These are made of mylar, correct? Are they pvc, oil & acid Free? I want to use them for coins.

Item description does not verify your questions. I would contact the mfg. Sorry I could not be if more help. They are food safe LPDE

If I use a single hole puncher to put the stuff in a binder, think the hole will rip the bag open?

Since the bags are 4 mil thick, depending where on the bag you're punching the hole, make sure it's not too close to the edge of the bag then, I think you'll be fine! 4 mil thick is the thinnest I purchase these bags in, I like to use them for storing jewelry in. But, if you go up to 6 mil or even 8 mil thick, you'll love those! Hope this helps!

the picture shows 50 pcs and the description shows 20 pack...how many 16x20 bags are being purchased?

about 20 I didn't count but it wasn't 50
