As the title says, is a polypropylene sheet a safe way to store autographs? Thanks :)

I don't know. But seeing how no one else has answered your question... Just look for "acid free" and "archival safe" on the package. If those statements are not there, then I would not take a chance with it.

What are you looking to store in them?

Autographs. Thanks man. It does not say acid-free, but it says something similar to "archival safe"

Well, I knew you were going to store autographs, but what I meant was: What kind of item? Magazines? Photos?

From what I've seen, virtually all sheet protectors are made from polypropylene, so it should be safe. Either that, or we're all screwed.

Stay away from anything that says Polyvinyl chloride (PVC). Polypropylene is fine. Almost all archival safe, acid-free sheet protectors are made from polypropylene. A way to know if you're using PVC sheet protectors is to smell them. If they have a strong plastic smell, they are my likely PVC. Polyvinyl chloride doesn't have any odor. I dont think PVC sheet protectors are made anymore, so I wouldn't worry about them. I remember back in the 80's, early 90's almost all sheet protectors were made from PVC. After a while PVC fades and sticks/melts onto anything that touches it. Just be on the look out. {up}
