Elimination of Aluminum Foil for 81-mm and 120-mm Mortar Ammunition Fiber Container

摘要

United Ammunition Container (UAC) in Milan, Tennessee is the current contractor that produces mortar ammunition inner packing fiber containers for the U.S. Army. UAC has not been able to secure any manufacturer that will agree to produce the needed aluminum foil. Apparently, it is not within the commercial standard manufacturing range, which is projected today due to its thickness, temper, and slit width. Not just any material can be used. The U.S. Army Armament Research, Development and Engineering Center's Packaging Division had suggested an alternative commercially available foil, but his is not possible due the nature of the winding process and the pressures involved. As a result, it was decided that water-vapor permeability study be conducted to compare the moisture protection performance of polyethylene laminated ammunition fiber containers with and without aluminum foil.
