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

Abstract

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.
