The work aims to lower the transport hazard of the PAB factory package by packaging improvement. According to the results of the UN6c test of PAB, and combined with the analysis of LS-DYNA dynamic finite element software, the packaging in the forms of mesh-like cages and strip-like cages was successively used to control the metallic projections. The metallic projections with kinetic energy exceeding 8 J and 20 J were successfully restricted by the packaging with strip-like cages, so that the PAB factory package successfully passed the UN6c test. The improved packaging meets the relevant requirements of dangerous goods' packaging in recommendations on the transport of dangerous goods (TDG). The PAB factory package originally classified into Class 1 (explosives) is reduced to Class 9 (miscellaneous dangerous goods), and can be transported in more forms.
