It also says in the article that: "Another chemically inert product is polypropylene, which is slightly less clear than polyester like Mylar, but is also considered acceptable for long-term preservation."
Binder pages and penny sleeves are made out of polypropylene. So, if you want to keep using the top loaders, you could put the cards, as many do, in the penny sleeves before you put them in the top loaders.
I also just put them in the top loaders also. I'm not going to worry about it. I like the immediacy so to speak, of just putting the card in the top loader and going through and looking at the cards that way. It's the closest to how we handled them as kids. But that said, I do also have a lot of cards in binders!
