The definition of thickness test: the height of corrugated cardboard under a certain pressure is called the thickness。Know the definition，It should now be clear that the importance of carton thickness testing: if the cardboard is in the process of processing，Corrugated height loss is too large，For example, after die cutting，Immediate impression，Grooving or printing，It will greatly reduce the compressive strength of the carton，Therefore, maintaining the thickness of corrugated cardboard should become a key part of the production process;Now judge for yourself the significance of the carton thickness test，So when choosing a good packaging manufacturer，We have to think carefully about our partners。

Factors of carton deformation

The deformation of packaging due to static or dynamic load during transportation and use。Due to the action of the force on a part of the package to form a concentrated load, so that the packaging breaks or produces permanent deformation caused by the deformation of the package。The size of the deformation value of the package and the maximum load it can withstand depend on the packaging strength of the carton, and the packaging strength depends on the structural properties of the cardboard material。
