WebThe McKee formula is expressed as Compression Strength = 5.874 * ECT * CAL0.508 * PER 0.492 (For more information on the McKee formula, please refer to the August 1963 issue of Paperboard Packaging, Compression Strength Formula for Corrugated Boxes by R. C. McKee, J. W. Gander, and J. R. Wachuta published by The Institute of Paper … WebThe most common formula in the packaging industry is the approach presented by McKee, Gander, and Wachuta in 1963 [3]. The authors formulated a relation- ship between the box perimeter and two corrugated board parameters, which are ECT and flexural stiffness. Two earlier approaches also took into account parameters of the paper- board [4,5]. scentsy pineapple warmer https://elyondigital.com
