A diaper is packed by being vacuum-sealed within a vacuum chamber. The method includes: (a) disposing a compressible absorbent diaper within an interior space defined by a flexible substantially air impermeable encasement within a chamber, the chamber for creating a vacuum state and sealing the encasement disposed within the chamber; (b) creating a vacuum state within the chamber and the interior space defined by the encasement; (c) sealing the encasement within the chamber such that the interior space of the substantially air impermeable encasement is completely sealed, and such that the compressible absorbent diaper is completely enclosed within the sealed interior space; and (d) pressing at least a portion of the compressible absorbent diaper with a smooth surface to flatten a face of the diaper.
