The purpose of this study was to evaluate the effect of horizontal offset on the compression strength of stacked box configurations. Four different boxes of varying sizes and similar board combinations, made from similar flute but different manufacturers were studied. The single box compression strength for each type of box was determined to represent as the control for this study. The compression strength of control boxes were compared to overall strength of a three-high stack and in three different offset configurations. In addition a set of perfectly aligned boxes were compared to overall strength of a three-high stack and in three different offset configurations. In addition, a set of perfectly aligned boxes stacked three high we compression tested for comparison with control and mis-aligned stacked boxes. The stack configurations were offset either in the length, width or diagonally (both length and width) with an offset distance of 12.7 mm, 25.4 mm or 38.1 mm (0.5, 1, and 1.5 inches).
