Nazdar PA series poly-all screen ink has been designed specifically for screen printing on untreated polypropylene. Its unique formulation makes pretreatment such as flaming or surface coating unnecessary. Poly-all will perform satisfactorily on most polypropylene surface. However, since there is considerable variation in the formulation of substrate materials, the user must always pretest the specific substrate for adhesion and product resistance prior to a production run. PA series inks exhibit a semi-gloss finish. When thoroughly dried, PA series ink has very good flexibility and durability. Poly-all has proven successful in some pad printing applications.
