Abstract: This study aimed at the application of Wolf formula for structural design of corrugated box for dairy products. Five kinds of corrugated boxes for 350 mL of Momchilovtsi, a Bright Dairy yoghurt brand, were designed according to the capacity and arrangement of the inner packaging, and their theoretical compression strength was calculated using Wolf formula as well as their minimum compression strength when 10 boxes were stacked and stored in the same environment using compression formula. Comparative analysis of the results of both calculations was carried out based on structural design elements such as ratio of length to width and length of sides. Moreover, verification was achieved using compression tests. Finally, we established the optimal structural design of 350 mL corrugated boxes for Momchilovtsi. It was showed that corrugated carton No. 4 had the highest marketability under the conditions: the same material and height, 3 × 3 arrangement mode, length/width ratio of 1, and length of sides of 74 mm.
