Abstract :
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, transparent and opaque polyethylene. Adhesion of samples increased from polypropylene to polyethylene while opaque polyethylene had better adhesion compared with transparent one. However, scratch resistance and optical properties of samples were independent of the 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.
