CUSHIONING MATERIAL FOR PACKAGING

摘要

PROBLEM TO BE SOLVED: To provide a cushioning material that protects a packaged object from shock and enables the packaged object to share part of the load of a stack. SOLUTION: The cushioning materials 9 and 10 for packaging, which are arranged between the upper part of a packaged object 1 and the corners of the outer box 7 are provided with cushioning projections 11 that are disposed so as to project from the top faces of the cushioning materials 9 and 10 in order to define empty spaces between the top faces of the cushioning materials 9 and 10 and the top face of the outer box 7 and so as to be elastically compressible according to the compression deformation of the outer box 7. The area of the projection is obtained by dividing the withstanding pressure load of the packaged object 1 by a coefficient obtained by taking the stress capable of being demonstrated by the material itself and the dispersion of the stress to the surrounding into consideration.
