A lot of reasons led to a carton production after breakage
First: the board thickness is not up to the conventional requirements, so the cartons compressive strength is lower;
Second: carton box size unreasonable (carton length, width, broken relationship dimensions and carton high larger);
Third: printing design of carton unreasonable (printing on corrugated cardboard will cause some damage, stress and under the size of the area is a major factor affecting the cartons compressive strength;
Fourth: flat carton intensity is low, the rigidity is low, so the compressive strength, puncture strength are small;
Fifth: the poor adhesion strength of cartons, resulting in low cartons compressive strength, and affect the whole carton strength.
