This article is a description of recent work in the development of composite sheet materials from blends of recycled high‐impact polystyrene (HIPS) and high‐density polyethylene (HDPE), with a view to using them as synthetic paper for the printing trade. Four monolayer films of differing composition were characterized in terms of their physical and surface properties. They were further evaluated compared with each other and with commercial synthetic and cellulose papers, to discover relationships between CaCO 3 filler loadings, film structure and properties that could lead to improvements. In terms of their whiteness and water base inks printing properties, these sheets were generally inferior to the cellulose and synthetic papers. Notwithstanding this, in some tests they showed superior quality; thus, in offset printing, the high surface gloss, probably due to the HIPS content, made the colors brighter in some mono‐oriented film samples.
