Abstract
A method for automatically designing a buffer packing size and a computer accessible storage media to store program thereof are provided. First, a buffer thickness of a buffer material is calculated, and a buffer area for a surface of the object receiving an impact is calculated according to a weight of an object and a static stress of the buffer material. Next, a suitable buffer packing size is automatically calculated according to the buffer thickness and the buffer area.
