Wilhelm rates the Epson Premium Glossy papers as having a long life.  
While the surfaces are acidic, tear one open and test the paper 
inside.  I think you'll find it is buffered, unlike most of the older 
glossy inkjet papers.  Whether this is enough for long term storage is 
may be another question.

I wonder also if the plastic in all these papers may be more of a long 
term problem than the acidity.
