Abstract: Hold down elements for interior walls in a cotton compacting chamber of a cotton packager, which facilitate holding or retaining compacted cotton in a compacted state in the chamber, without significantly interfering with or restricting unloading of a cotton module from the chamber, or reducing structural integrity of the module. One or more of the hold down elements can be utilized on an interior wall, and the hold down elements are oriented so as to extend longitudinally in an unloading direction, such that a cotton module will slide therealong without being held in the chamber by the hold down element.
