Photo Archival Sleeves

[Edward H. Lybarger]

As long as the word "vinyl" doesn't appear anywhere, they're probably OK.  I
use primarily polypropylene, though polyethylene works but is softer.
Plastic is fine for safety film stored  in air-conditioned environments
(excessive heat can cause the negatives to ferrotype to the sleeve).  If you
have any nitrate negatives (nitrate-based film not sold after about
1950-51), they should be kept in buffered paper so they can breathe.

I like plastic because I can see the negative easily.

Greetings!

	Plastic sleeves specifically for storing photographs in various sizes
are on the Market.
	I notice that Avery, an extremely well know paper products company,
sells *Heavyweight Sheet Protectors* and the box says that they are
*Archival safe; Won't lift print; Acid free.*
	The box says nothing about photo usage - just paper.  Would it be safe
to store photographs in these sleeves?  They seem considerably less
expensive than a comparable product sold in photo shops and are
available at places like Staples and Office Depot.
