摘要： Disclosed is a control method for a transverse to longitudinal crease stiffness ratio, belonging to the packaging field. The transverse to longitudinal crease stiffness ratio represents the ratio of a transverse crease stiffness to a longitudinal crease stiffness, and the transverse to longitudinal crease stiffness ratio is controlled to be ≤1.25. The control method of the transverse to longitudinal crease stiffness ratio in the present invention enables to control the transverse to longitudinal crease stiffness ratio within a certain range by adjusting the height of a die-cutter or adjusting the width of a bottom die.
