Fractal widely exists in the properties of packaging materials. There is no systematic description at present. It is necessary to summarize the research progress of fractal theory applied to packaging material properties, so as to provide reference for the research of improving packaging properties by fractal application. The fractal analysis methods applied to inorganic materials such as metal alloys and ceramics, high-molecular polymers and composite materials were reviewed from the aspects of fractal feature extraction and fractal dimension calculation methods. Through the fractal dimension model of packaging materials, the relationship between the fractal characteristic parameters and the properties of packaging materials was analyzed. The fractal analysis method can qualitatively and quantitatively characterize the fractal characteristics, microstructure and mechanical properties of a large number of different types of packaging materials. The method of using fractal theory to study the properties of packaging materials is universal. The relationship between the properties of packaging materials and fractal dimension will be one of the important trends of fractal theory in the research of properties of packaging materials.
