Abstract

The present invention relates to a process of preparing non-laminated blended biaxially orientation extruded polyester film without any co-extrusion layers with the voids being dispersed in the monolayered film for applications as base material for label, poster, recording paper, wrapping paper including reflector of a surface light source for illuminating a scope of liquid crystal displays or electronic decorative boards. Such films exhibit % transmission of 10 % max, reflection at 450 nm, 550 nm and 650 nm of > 90 %. An appropriately blended composition comprising a mix polyester, a polycondensed resin of a dicarboxylic ester and polyhydric alcohols, density reducing polymers, optical brightners and inorganic particles is extruded and processed to produce the non-laminated biaxially oriented polyester film.
