Abstract

The work aims to explore the effect of the crease depth of cigarette packaging paper on the folding performance and the adaptability for production line, so as to optimize the packaging process parameters and improve the quality of product packaging. A combination of experiments and numerical simulations was used to study the mechanical behavior of box trademark paper folding under different crease depths. Under the same crease width, as the crease depth increased, the crease stiffness showed a decreasing trend, but an excessively large crease depth caused the secondary stress concentration, increased the crease stiffness and negatively affected the corner morphology. The simulation model can simulate the folding process of the trademark paper with high precision. The effect of the crease process on the folding behavior of the box packaging paper mainly lies in its adjustment of the stress concentration during the folding process and the resulting material damage.
