Is the harder the corrugated box, the better

1. How to judge the quality of corrugated boxes
Whether the quality of a carton is qualified needs to look at three indicators, the first is the bursting strength of the carton, and the bursting strength is the uniform pressure value that the unit area of cardboard can withstand. The second is the variable pressure strength of the carton, which is the ability of the corrugated box to withstand pressure parallel to the corrugated direction. Finally, the compressive strength of the corrugated box, which refers to the force generated by the uniform increase of displacement to compress the carton, and the force that the carton can withstand. These three points are the standards that really determine the quality of the carton.
2. The connection between corrugated box hardness and carton quality
There is no necessary connection between the hardness of the corrugated box and the quality of the carton. There are many kinds of materials for corrugated boxes, and the hardness of the corrugated boxes made by using different materials is also different, and the uses will be different. This cannot be killed by a rod, and if the hardness is low, the quality of the carton will not be good. We need to choose the most suitable paper carton according to our actual use.
