Abstract

During recent decades due to the increase in pollutants release from various industries, reduction or elimination of volatile organic compounds VOCs has become one of the main purposes of researches in order to protect the environment. In this research, two acrylic emulsion resins and an adhesion promoter polyester emulsion resin were used to optimize water-based printing ink formulation for printing on polyolefins. Then resistance properties of printed films were evaluated. The used polyolefins were transparent polypropylene PP, transparent and opaque polyethylene PE. Adhesion of samples increased from PP to PE while it was better for opaque PE compared with transparent ones. However, scratch resistance and optical properties of samples were independent of substrate. SEM images showed that the samples with Zinpol 350 had larger structure which caused the gloss decrease while for samples containing Glascol LS26 high level morphology and small microstructure lead to higher gloss and adhesion properties.
