Abstract: The invention relates to a transparent, biaxially oriented polyester film with a base layer B formed from at least 80% by weight of a thermoplastic polyester, and with at least one outer layer A. The outer layer A includes polyesters and poly(m-xyleneadipamide) in certain concentrations. The invention further relates to the use of the film and to a process for its production. The transparent film has very low atmospheric-oxygen transmission and exhibits very good adhesion between the respective layers. It is particularly suitable for packaging purposes, specifically for the packaging of foods and of other consumable items.

Abstract: The invention relates to an aqueous coating composition which comprises a mixture of polyvinylpyrrolidone, a surfactant and optionally an adhesion-promoting polymer. This mixture is suitable for inline coating of biaxially oriented polyester films. The thus obtained films feature a characteristic hydrophilic surface which prevents the fogging of the films with water droplets.

Abstract: The invention relates to a transparent, electrically conductive, biaxially oriented, single- or multilayer polyester film which includes a coating composed of (a) conductive (ITO) indium tin oxide particles or (ATO) antimony tin oxide particles, or of a mixture of these. The film further include other conductive components (b). The other conductive components (b) may be present either in the coating including ITO particles and/or ATO particles or in a layer in contact therewith. The conductive component (b) may also be a metal layer in contact with the ITO and/or ATO. The film is only oriented or relaxed prior to application of the ITO and/or ATO coating. The invention further relates to a process for the production of the film, and its use.
