The purpose and method of this paper is to comparatively analyze several commonly-used cushion packaging materials, obtain their shock absorption characteristic curves, and by doing such, provide reference information for cushion packaging design and research. With the static test, dynamic compression test and vibration transfer test carried out, the cushion coefficient ~ static stress curve, maximal acceleration ~ static stress curve and vibration transfer rate ~ frequency curve are gained. A final conclusion is educed that in practical design routine, rational choice of cushion packaging materials, scientific design of packaging structure and validation of anti-vibration capability are relative to those three curves.

A new green packaging material—honeycomb board was studied. Several main technical parameters were tested and some advice was put forward on development of honeycomb board.

Corrugated board is a packaging material with many advantages and widely used. Based on the performance of corrugated board, its cushioning package application was studied, the CAD system of transport package was designed, which changes the process of traditional packaging design, cuts the cost, improves the efficiency and shows a broad application prospect.

The paper simulates the airflow in the microenvironment of negative pressure isolation cabin for the infectious disease patients. The result shows that the proper setting of such parameters as air inlet, air outlet, fan flow rate, and differential pressure control can effectively discharge the contaminated air out of the tank after the air is efficiently filtered. During the cabin ergonomic evaluation experiment based on different negative pressure values, the temperature and humidity rise slightly compared with the external environment but there is no obvious accumulation. Besides, the human life indication is consistently kept in the normal range.
