Abstract
The antistatic treatment of printing inks for polyethylene with surface active agents as antistatic agents was studied. Surface resistivity and charge generation of printed inks incorporated with surface active agents on polyethylene filmes were measured.
Some cationic and amphoteric surface active agents exhibited the good antistatic property. Furthermore, it was found that the printability (adhesion strength) of inks incorporated with some cationic surface active agents to polyethylene film was improved, and polyethylene film incorporated with internal antistatic agents showed the better printability than blank film.
Authors believe that the orientation of the cloes packed molecular layer of surface active agents on polyethylene film, its surface polarity and wettability of both polyethylene film and printed ink surfaces are essential for exhibiting the excellent antistatic property and printability between polyethylene and inks.
