Evaluation of Mechanical Strength of Five Layer Corrugated Cardboard Depending on Waveform Types

Due to the growing need for saving material in the production of paper packaging, its industrial production is faced with the problem of assuring quality. By controlling the cost of corrugated cardboard production, mechanical properties depend directly on flute profile. Therefore, the corrugated cardboard can be observed both from technological and environmental aspects. For this research five-layer corrugated cardboard of different types of flute profile was used. It is assumed that the characteristic shape of the wave has a positive effect on its mechanical properties. On the other hand, it is assumed that the saving of the material can be achieved through characteristic flute profile without reducing cardboard mechanical strength. The aim of this research is to determine whether there is a direct impact of waveform type on mechanical strength. Statistical methods were used for the evaluation of expected values of corrugated cardboard estimated strength with respect to the flute profile.
