The invention discloses a low haze polyester film, which is a co-extruded film. The co-extruded film comprises a first surface layer and a second surface layer and a base film sandwiched between the first surface layer and the second surface layer. The first surface layer and the second surface layer are made of PET. The first surface layer is uniformly distributed with first inorganic particles, and the second surface layer is uniformly distributed with second inorganic particles. The particle size of the first inorganic particles is 10-120 nm. The second inorganic particles The particle size is 0.5~5μm. The co-extruded low haze polyester film has the first inorganic particles and the second inorganic particles evenly distributed in the first surface layer and the second surface layer, respectively, and the first inorganic particles are smaller than the second inorganic particles, so that the transmittance of light is improved, Reduce light deviation to reduce haze. |
