| Abstract:On the basis of analyzing the performance of typical printed cigarette packet packaging paper and cigarette packaging adhesive， the contact angle and width changes of adhesive droplets on the surface of the adhesive area of packet packaging paper were studied， and the effect of adhesive opening time on the adhesion strength was explored. The results showed that when packaging adhesive droplets were added to the surface of packet packaging paper， whether on the printed or non-printed surface， the contact angle continued to decrease and the droplet width continued to increase over time. The time for the two to reach equilibrium was different. The decrease in droplet contact angle was the result of the joint action of expansion and penetration， while the change in droplet width was only related to expansion. Different combinations of packet packaging paper and packaging adhesive had different changes in droplet contact angle and width， as well as different opening time windows for gluing. It was related to the viscosity and solid content of the adhesive， as well as the expansion and permeability of the packet packaging paper. The wettability of water on packet packaging paper was significantly different from that of adhesives， and the wettability of water on the surface of the paper should not be used to determine the behavior of adhesives. |
