Safety factors in the design of corrugated board packaging

The paper briefly presents the most important safety factors that are most often used in the process of estimating the load-bearing capacity of corrugated board packaging. first, the coefficients taking into account storage and transport under various environmental conditions are discussed. These factors directly increase the safety of the transported packaging by increasing the required load capacity. coefficients that indirectly affect the value of the estimated load capacity of the packaging are discussed next. They are usually added during the estimation of the theoretical load-bearing capacity by taking into account the uncertainty related to the declared quality of the material, as well as the impact of damage to the structure of corrugated board during converting. both types of coefficients are shown through the schemes adopted by packaging manufacturers. Unfortunately, these procedures are subject to errors or simplifications, which often lead to overestimation or underestimation of the load-bearing capacity of packaging. In both scenarios, wrong estimation involves additional costs that can be easily avoided. Therefore, determining the appropriate values of these coefficients is very important, but at the same time difficult, especially when the designed packaging will be stored in varying environmental conditions, with multiple handling and additionally transported by different means of transport.
