The purpose of this paper was to summarize the current researches on development of the plant fiber porous cushioning packaging materials. The research status was analyzed by combing foreign and domestic literatures about plant fiber porous cushioning packaging materials and classifying the existing researches by raw materials and components, foaming methods and molding processes. In conclusion, the application of plant fiber porous cushioning packaging materials plays a very important role in improving the utilization of natural resources and easing the pressure on the environment caused by usage of foamed plastic. And this summary provides reference for the further research on plant fiber cushioning packaging materials though suggestions on solving the problems such as foaming mechanism.
