Study of the mechanical properties of cardboard with barrier properties

Abstract

The aim of this study is to test and compare the mechanical properties of the cardboard selected for the tests and to determine the best type of material. As cardboard is used in a wide range of industries for the packaging of goods, it is important to determine which of the types of cardboard tested is the most resistant to wear and the least deformable under changing environmental conditions. It is also important to compare and identify what improvements could be made to existing materials to make the board durable and environmentally friendly. To conduct the experiment of this study, four types of cardboard with barrier properties were used. For all the tests sample groups of different cardboards with different barrier properties were prepared and the specimens were stored and acclimatised under the same conditions before the tests. Specific software and devices were used to determine the final results. Selected types of tests were chosen to compare the types of cardboard as they are close to the real-life use of the packaging. After obtaining results of selected tests, compared values have shown that there were no significant changes, but there were some differences in the strength properties, which could be mainly due to the different mechanical properties of each type of paperboard. As a result, one type of paperboard was superior in both resistance and wetting tests. To conclude, this study, which was carried out to compare the strength properties of four different types of cardboard and their behaviour caused by changed surroundings demonstrates that all the types of tested cardboards are proper for use but need to be protected from direct wetting or wearing and tearing. Furthermore, this study helped to obtain new directions and ideas on how cardboard could be improved and made an even more resilient but environmentally friendly material and how it could be improved and applied in industrial companies in the future.
