Lead to substantial damage to the carton making reasons

First: the thickness of the cardboard does not meet General requirements, so low compressive strength in cartons;

Second: carton box size is not reasonable (carton of length, width and height dimensions of breakage and more);

Third: the unreasonable design of carton printing (printing on corrugated board can cause damage of pressure and size of the bearing area is a major factor affecting the BCT;

Part IV: the carton flat low strength, rigid or low compressive strength, small puncture strength;

Five: the poor adhesion of the box, resulting in a low compressive strength in cartons, and affects the strength of the box as a whole.
