Earlier surface analysis studies have suggested that, at least in some situations, the print adhesion properties of barium/zinc stabilized, stearic acid‐lubricated PVC are influenced by the migration (exudation) of a barium/zinc stearate complex. This paper expands the previous study in attempts to reproduce the effects observed on samples of commercially produced films, explain the origin of the migrating specie, and identify the variables that influence the extent to which the phenomenon occurs. The effects of different lubricants, stabilizers, and processing conditions are studied. Mechanistic work suggests that a revised hypothesis is appropriate and that the hydrolyzed complex is actually formed in the PVC matrix and not at the surface.
