Does anyone know the simple way to check the hardness of carton?
Hardness is just one touch of yours. To achieve the hardness you require, mainly to test the base broken, ring pressure. The scratch strength, edge pressure and bursting resistance of paperboard. The last thing you can do is to reach the strength of your box. Oh, I am also a bird, you have to consult more upstairs
Brother, did not appear the problem in carton hardness detection. According to the situation you say, is probably the cartons compressive strength is too low. To test the compressive strength of special carton press. In addition, anti puncture strength is a very important technical index is carton. If can ensure that the two the technical indicators, then your carton should be no problem.
When I was an intern in a small corrugated carton factory before to see people with a high degree of broken instrument detection board, when the board is numerical instrument operator record shows the breakdown time, measured ten times the average. It is estimated that this is to ensure the load-bearing capacity of the carton
