Blends of linear low density polyethylene (LLDPE) and linear low density polyethylene grafted polyether pentaerythritol mono-maleate (LLDPE-g-PPMM) were prepared by melt mixing. The surface of LLDPE/LLDPE-g-PPMM films with different contents of LLDPE-g-PPMM was characterized through contact angle and FT-IR spectroscopy. The tensile properties and light transmission properties of extruded films, as well as the performance of these films compared with commercial anti-fog films, were determined. The carbonyl polar groups on the surface of LLDPE/LLDPE-g-PPMM films increased, and the contact angles of water and glycerol decreased when the content of LLDPE-g-PPMM increased. LLDPE/LLDPE-g-PPMM films showed a noticeable reduction in water drop formation as the LLDPE-g-PPMM content was increased. The transmittancy and haze of LLDPE/LLDPE-g-PPMM films were improved when using increased contents of PPMM, which promotes better wetting of the water on the surface.
