Any materials considered safe for use in exhibit cases is also appropriate for
storage environments. Start with the National Park Serivce (USA) web site:
The Exhibit Conservation cd-rom
http://www.nps.gov/hfc/products/cons/ex-con-guidelines.htm
In the US, many wooden storage structures are made of clear poplar sealed
with a waterborn sealer. Poplar is a stable wood and not acidic. Exhibit cases
are often sealed with a product called Marvl Seal or are faced with Formica
(tm), also a stable product.
Best of luck
