The current Reel 3D catalog says the sheets are "vinyl".  Vinyl is NOT
archival.  The Light Impressions catalog says that PVC (polyvinyl chloride),
a major component of vinyl plastics, can decompose to hydrochloric acid (HCl).

Any kind of acid exposure has a deleterious effect on paper mounts and film
emulsion.  I would not store my precious slides in vinyl sheets!
