UV Flexo inks are becoming increasingly popular in flexible packaging .The ever-increasing improvements in UV Flexo inks such as print quality; low ink maintenance requirements, no solvents, high press stability, and in-line finishing have all contributed to converters’ decisions to switch to UV Flexo system. Recently, new UV flexo ink systems have improved efficiency and production. Hence, many substrates are coated with a primer to perform as adhesion promoter. Nevertheless, this additional coating are not always successful, increase cost to the convertor and typically do not mitigate the migrating effect of lubricating additives found within certain flexible packaging films. This paper will detail, in the absence of adhesion promoters, the effects of corona, flame or atmospheric plasma surface treatments on the adhesion of UV flexo inks to flexible packaging films Flexo printing first came onto the market in the 1960’s and began as a relatively simple and low-tech printing method and today it has become a state-of-the-art printing method, requiring high-tech printing inks to achieve high-quality printing results UV flexographic ink system that provides excellent light fastness on a wide range of plastic materials for outdoor use. UV curable system has specially designed for application in Flexo Printing process.
