The aim of this work was to study and explore the free drop buffering technology, to enrich air-drop support measures and improve air-drop support ability. Using liquid edible materials as the study object, based on thoughts of buffering packing, aided by numerical simulation and high-altitude air-dropping test, successful high-altitude free drop of materials from 200 m was realized by choosing suitable buffering packing materials and scienti fic design of the packing style. The chosen packing materials, the adopted packing structure and style, and the multi-level buffering pattern of different materials all contributed to the satisfied needs of free drop of liquid edible materials, and secured the intactness and usability of the materials after landing. Free drop is a kind of practical, convenient and economic air-dropping support style, especially for large amount materials of low value, free dropping is both feasible and of great significance.
