The research status of package dropping impact was introduced. The development status of package dropping was discussed in detail from four aspects, including dropping impact mechanism, impact dynamics, test and simulation, and the problems in every aspect were pointed out. The influences of factors such as time, damping and friction were neglected in many empirical formula about dropping impact mechanism; Physical test has a long test period and high test cost, and it is difficult to observe the internal change characteristics of packaging products after impact. Theoretical analysis is only suitable for studying simple single degree of freedom packaging system. The simulation technology solves the disadvantages of physical experiments and theoretical analysis. The simulation technology is very immature at the moment, and many databases have to be established in future.
