Abstract: A single-layer or multi-layer, biaxially oriented polyester film is provided bearing on at least one film surface a coating for transparency increase. The film has a particle fraction of not more than 0.5% and the coating is a dried water-based or solvent-based solution and/or dispersion having a dry coat thickness of 60-130 nm. The coating includes at least one acrylic acid-based and/or methacrylic acid-based polymer and at least one alkylphosphonate and/or oligo-alkylphosphonate. The coating has a refractive index n<1.64 and a phosphorus fraction of between 2 and 18%. The inventive film is suitable for producing greenhouse energy-saving sheets, particularly for the growing of plants with exacting light demands such as tomatoes. The film has specific transparency properties, high UV stability and good fire properties. The invention further relates to methods for polyester film production and also to the use thereof in greenhouses.

Abstract: The invention relates to a single- or multilayer polyester film with transparency at least 93%, where the film includes a UV stabilizer in all film layers and has a permanent antifog coating on at least one side. The permanent antifog coating is the dried product of an aqueous coating dispersion having the following components: a) from 1 to 15% by weight (based on the coating dispersion) of a soil release polymer and b) from 3 to 15% by weight (based on the coating dispersion) of a hygroscopic, porous material. The invention further relates to a process for the production of the film and to its use.
