Documents should be stored in a primary archival enclosure such as a folder or envelope. The primary enclosure should then be stored in an archival box.
 
The primary enclosure can be any of the following depending on individual preferences.
A: Paper Enclosures
    1. File Folders
    2. Envelopes
    3. Manuscript Folders
B: Polyester Enclosures
1.        Envelopes
2.        L-Seal Sleeves
3.        Binder Pages
4.        Folders
C. Polypropylene Enclosures
1.        Envelopes
2.        Sleeves
3.        Binder Pages
 
When more than one document page is stored in the same primary enclosure, it is helpful to place interleaving archival sheets between the document pages. For example, a frequent practice is to store a number of document pages in an archival file folder with archival bond paper placed between the document pages.
 
It is very helpful to spray poor quality paper documents with a deacidification solution before storage. Newspapers will benefit greatly from this treatment.
 
After documents are placed in primary enclosures, they should be placed in an archival storage box that is a suitable size to house the primary enclosures. Documents stored in polyester or polypropylene binder pages can be housed in an archival binder album.
