Abstract

In this study, the effect of humidity on the ECT and Burst strengths of corrugated fiberboard was investigated using a conditioning temperature of 90F combined with relative humidity, RH, of 30%, 50%, 65%, and 80%. The primary focus of the study was on the bidirectional property of corrugated fiberboard in terms of the ratio of the ECT strength in the weak direction (perpendicular to the flute direction) to the strong direction (parallel to the flute direction).  The ratio is not constant, but increases at the rate of 0.0017 per % RH per the following equation: ECT Ratio (Weak/Strong) = 0.0017(RH) + 0.4719.
