The correct choice of the cushion material of economical practical foaming plastic or the cushion material of new environmental protection must be made according to the reality. Therefore the test, comparison and analysis research need to be carried on the different cushion material especially their resistant to compression performance. Then the choice and application of the cushion material made by considering their efficiency, the environmental protection, sustainable. The objects of the topic in this research mainly are EPE, EPS, and the corrugated liner and so on, which are the common cushion material and some new environmental protection cushion material like materials of honeycomb cardboard, the paper pulp molding, the inflated pearlier cushion liner, the air cushion. The paper discussed on the base of the main existing problems of cushion packing material and the progress of research on the cushion material of environmental protection, studying the function of different cushion material through experiments and analyses. The empirical formulas or the fitted curve can be obtained by testing and analyzing the function of static, the dynamic of the cushion materials, the cushion material, resilience, and including the factors of the cost, recycling, whether could be degraded, the above mentioned provide the best theory and empirical datum for the choice of design of cushion packing materials. Key words: The characteristic of compression, the cushion material, resilience, degradable
