Sharon, it's not just a matter of which box vendor to choose:  it's also a matter of the box design.

For example, we store vendor payment vouchers which are loaded "wall-to-wall" in standard 1.2 CF boxes (no folders), and the weight is much greater than the usual office files. So we've purchased triple-wall boxes solely for use with these records.

Also, if these records are intended to be stored for a VERY long time (i.e., more than 50 years) and are intrinsically valuable, you might consider two other factors:  the storage environment -- which, in most ordinary facilities is not climate-controlled in any way -- and the use of boxes made of materials considered "archival".

With respect to the storage environment, a good reference is NISO TR01-1995 "Environmental Guidelines for the Storage of Paper Records" National Information Standards Organization (NISO) http://www.niso.org/publications/tr/tr01.pdf.

With respect to the box materials, you might check out "Specifications for Housing Enclosures for Archival Records" (2015), U.S. National Archives, https://www.archives.gov/preservation/storage/specs-housing-exhibition-2015-current.html. It covers boxes and other, related, storage materials.
