Study on the Effect of Additive Content on the Performance of Waterborne Flexible Printing Ink Used on Films

Under the trend of environmental protection, as a kind of environmentally friendly printing ink, research printability of flexible printing ink used on films has been paid more and more attention by enterprises and the market. In order to, effect of the content sofwetting agent W1 and mixing wetting agent on waterborne ink were researched to improve the printability effectively. Wettability of waterborne ink was increased firstly and then decreased with the increase of wetting agent W1content. The optimum amount of W1 is 0.4wt% W1, W2 after the combination of flexographic waterborne ink wettability is better than simply adding W1 wettability, its complex ratio of 1:1, the wettability of waterborne ink is the best. The printability of water-based flexible printingink used on films was improved by adjusting the appropriate content of wetting agent and thickener.
