This would certainly protect the stamps, but I am concerned about potential long-term damage (like the old clear mounts that shrunk and sometimes became adhered to the stamps).
Experience? Comments?
Many thanks, Dave.

The National Postal Museum uses polypropylene sheet protectors but they do not mention brands. I use the heavy duty 3.3mil thickness that are large enough to hold several sheets so pages are not snug after insertion. The Avery pages are polypropylene not vinyl. Vinyl is not good.
"Polypropylene is similar to polyester film in clarity. It is also used as sleeves for storing photographs, papers and philatelic material. The museum often uses polypropylene page protectors for album pages when rehousing a collection."

Thanks Al. I use single-sided Steiner Pages now but I think these would be useful for double-sided album pages without the stamps latching on to each other as they do in commercial albums.

Dave, been using them for over 10 years with no noted issue (so far). I keep an eye on the very first sheets I ever used, but I also think that quality has improved, and I am fairly confident today.
One always feels uncomfortable with mixing "plastics" and stamps, long term, ever since scotch tape was briefly used (not even on the stamps, but to help close open ended mounts), with disastrous results.

Thanks Ralph. I have a number of nice/HCV stamps with the brown stains from scotch tape. Damn the Scots! (Apologies Ian).
I am feeling more comfortable with the protectors now - especially for albums a bunch of people may get their greasy fingers on.

I had purchased a collection that had items in protective sleeves were in poor condition. They were shriveled and a little slimy. The brand was c-line but not sure if they were polypropylene.
I have been using Avery, Wilson Jones, and Office Depot without any issues.
If you ever want to accelerate aging put some samples in a unconditioned space like an attic. and let the heat, humidity work on them,

Dave, I use the Ultra Pro Platinum Series pages. I use mainly the 2 pocket for my collection. I also have a pack of their 1 pocket (full 8.5x11"). They are marketed as No PVC, acid Free, ultra clear with UV protection.
Of course, most of us won't be around long enough to see if the pages deteriorate over time.

I think that depends on how many binders can be packed
in my coffin.

I am considering using these for my stamp albums in general - and for my "Philatelic History of The Holocaust" (and other) display albums that will probably be carted around and handled by numerous people.
This would certainly protect the stamps, but I am concerned about potential long-term damage (like the old clear mounts that shrunk and sometimes became adhered to the stamps).
