摘要： Embodiments of films, for example, infrared absorbing, heat retaining films, comprise at least one polymer selected from: a low density polyethylene (LDPE) having a density range of 0.900 g/cc to 0.930 g/cc and a melt index (I2) of 0.3 g/10 min to 2.0 g/10 min as measured in accordance with ASTM D1238; a linear low density polyethylene (LLDPE) having a density range of 0.900 g/cc to 0.930 g/cc and a melt index I2 of 0.3 g/10 min to 2.0 g/10 min; and a ethylene vinyl acetate copolymer having a vinyl acetate content ranging from 3 wt. % to 27 wt. % and a melt index I2 of 0.2 g/10 min to 10 g/10 min. The films also comprise a hybrid filler comprising (i) a layered double hydroxide, and (ii) an inorganic powder complex having a particle size distribution defined by a median diameter (D50) of 1.5 to 20 μm.
