Abstract

The present, invention relates to a highly transparent, biaxially oriented, UV-resistant polyester film which has, at least on one side, a coating that reduces reflection of visible light. The film of the invention is suitable for the production of energy-saving sheet materials for greenhouses, in particular for cultivation of plants with high light requirement, e.g. tomatoes. The film has specific transparency properties and high UV resistance. The invention further relates to a process for the production of the polyester film, and also to use of the film in greenhouses.
