AB - Typically, the measure of hydrophobicity in PVC films and sheets is a surface energy measurement in dynes/cm in the low‐to‐mid thirties. More recently, the trend has been to lower the amounts of solvents used in inks, coatings, and adhesives, which, in turn, are used to coat or print the flexible PVC article. With the change in the makeup of coating systems, a modification in the surface energy of the flexible PVC film is needed to make an inherently hydrophobic material more hydrophilic. It has been found that the combination of a polymeric plasticizer and a monomeric plasticizer in conjunction with a metal oxide, unexpectedly increases the hydrophilicity of PVC sheets or films by factors of roughly 25% to 33%. This paper discusses the results of an investigation leading to an increase of surface tension from 33–36 dynes/cm to 40–43 dynes/cm.
