Abstract
The invention relates to a single- or multilayer, biaxially oriented polyester film where at least one layer includes an amount of from 0.2 to <1.0 % by weight, based on the total weight of the film, of silicon dioxide particles whose median particle size, d50 is from 2.5 to 4.5 μm. The inventive films have particular suitability in the industrial sector, e.g. for greenhouses, for more diffuse light-scattering.
