Abstract Corrugated cardboard liner is a foam pad to gradually replace the environment-friendly packaging materials buffer structure, in line with the modern logistics and transportation applications packaging industry trends. The current performance of corrugated cardboard, at home and abroad has made great progress, and constant development. Buffer performance of corrugated cardboard are of particular interest to become the focus of the study, summed up the research at home and abroad that the performance of the corrugated cardboard buffer study, the methods are carried out through a large number of tests derived from an analysis of test data to identify corrugated cardboard with the basic characteristics of the methods of numerical analysis using a mathematical model, optimization method to use to identify the model parameters, this method is time-consuming and also a waste of resources and effort, and the whole process is extremely complicated and prone to error. Their study is the change in external conditions, such as temperature, humidity changes, such as corrugated cardboard cushion the impact of performance. In this paper, using finite element analysis software for the corrugated cardboard for the analysis of the buffer line, and the corrugated board is slotted with a three-tier structure of A-type corrugated cardboard, corrugated cardboard is the main structure in the case of static load its buffer performance analysis, b
