This study examines a new corrugated flute profile known as "K" flute. The purpose of the study was to show that K flute can maintain the same structural integrity and use significantly less paper. The main tests performed were tests for compression strength. Studying the results of compression testing, allows the designer to engineer the corrugated container to meet the performance level required. The study consists of two parts. The first part of the study examines the effect of an increase in caliper has on Edgwise Compression Testing (ECT). It was found that K flute tested 5% stronger than A flute, 22% stronger than C flute, 40% stronger than B flute. The next part of the study compared K flute as a substitute for commonly used grades of singlewall and doublewall, the results of the comparison are as follows: 275lb C vs 200lb K, the K flute tested 18% less in compression strength, used 61% less paper in the liner and 7.6% more in the medium. In the next comparison, 200lb BC vs 2001b K, the K flute tested 42% less in compression strength, used 18% less paper in the liner and 80% less paper in the medium. 200lb A vs 2001b K, the K flute tested 7% stronger in compression strength, it used 0% less paper in the liner and 2% less paper in the medium. 275lb BC vs 44ECT K, the K flute tested 23% less in compression strength, K flute used 3.6% more paper in the liner and 80% less in the medium.
