Matt biaxially oriented polyester film

摘要

The polyester film has a layer comprising 0.2 to less than 1 weight% of silicon dioxide particles with respect to total weight of the film, and UV stabilizer. The median particle size of silicon dioxide particle is 2.5-4.5mu m. The biaxially oriented polyester film has haze of 38-60 % and transparency of about 70-95% measured by ASTM D10003-00. The average roughness of the film measured by DIN 4762 is 170-1000 nm.
