Research on Equivalent Cushioning Property and Design Idea of Overlay Combination Cushion

Based on the research on application and design method of combination cushion, the equivalent cushioning coefficient formula of overlay combination cushion made by different cushioning material were derived, and the relevant cushion design method was proposed. The work provides a theory basis for the combination cushion design. The equivalent cushioning coefficient formula can be used conveniently as it is expressed by the material’s property parameters. The research can help to play the advantages of different materials, promote the integrated use of different materials, and carry out economic packaging, green packaging ultimately.
