The present invention relates to a process for recycling a polyester film that includes comminuting a used polyester film to shreds, the used polyester film including a polyethylene terephthalate polymer, melting the shreds in a twin-screw or multi-screw extruder, filtering the melt, and pelletizing. The present invention further relates to a process for producing a biaxially oriented polyester film that includes melting PET pellets in an extruder, at least 10% by weight of the pellets having been obtained by the process of the invention for recycling a polyester film. The present invention further relates to pellets and to a biaxially oriented polyester film, obtained by the processes of the invention, and also to the use thereof.

Biaxially oriented polyester film containing post-consumer or post-industrial regrind from a coated polyester film, and operation for producing the film and the regrind

The invention relates to an at least three-layer biaxially oriented polyester film including at least one base layer B, one rough outer layer A and one smooth outer layer C, where the layers A and C are external layers arranged on opposing surfaces of the base layer B. The outer layer A includes calcium carbonate particles. The outer layer C includes less than 0.1% by weight of particles (where the percentage by weight data are based on the weight of the layer). The polyester used to produce all of the layers includes no 2,6-naphthalenedicarboxylic-acid-derived units as repeating units. The entire film includes less than 0.3% by weight (based on the weight of the entire film) of particles. The invention further relates to processes for producing the film, and also to use of the latter as process film for the provision of surface properties, in particular for furniture surfaces.

Transparent, biaxially oriented polyester film with smooth surface on one side and with good windability

The present invention relates to an at least two-layer biaxially oriented polyester film with at least one matt surface and with an increased coefficient of friction of this surface, with a total thickness from 8 to 75 &#x3bc;m. The film of the invention has excellent suitability as an external ply of animal-feed bags with matt appearance which on stacking are not subject to slippage between the same.

Biaxially oriented matt polyester film with increased coefficient of friction

Biaxially stretched film with polymeric constituents formed mainly of polyester in which the film includes at least one copper salt and one halide, with the resulting film having an AC (alternating current) dielectric strength of at least 100 kV/mm at 23&#xb0; C. and 50 Hz. The invention further relates to the use of the film of the invention, in particular in solar modules, and also to a process for its production.

Biaxially stretched polymer film comprising a decarboxylation catalyst, its use in electrical insulation applications, and process for its production

The invention relates to biaxially oriented polyester films which contain 0.25-20% by weight (based on the weight of the film) of a hydrolysis stabilizer based on epoxidized fatty acid esters and/or epoxidized fatty acid glycerides, and a chain extender. Such films find use in outdoor applications, as a ribbon cable, as a backside laminate of solar modules and in electrical insulation applications.

Biaxially oriented hydrolysis-stable polyester film comprising epoxidized fatty acid derivatives and a chain extender, and process for production thereof and use thereof

The invention relates to biaxially oriented polyester films which contain-% by weight (based on the weight of the film) of a hydrolysis stabilizer based on epoxidized fatty acid esters and-% by weight (based on the weight of the film) of epoxidized fatty acid glycerides, the epoxidized fatty acid esters having a mean molecular weight of at leastg/mol. Such films find use in outdoor applications, as a ribbon cable, as a backside laminate of solar modules and in electrical insulation applications.

Biaxially oriented hydrolysis-stable polyester film comprising epoxidized fatty acid derivatives, and process for production thereof and use thereof

The invention relates to a multilayer polyester film comprising a hydrolysis stabilizer, wherein the hydrolysis stabilizer is an epoxidized alkyl ester of fatty acid or is a mixture of epoxidized alkyl esters of fatty acid or is an epoxidized fatty acid glyceride or is a mixture of epoxidized fatty acid glycerides, and at least one external layer of the film does not comprise the hydrolysis stabilizer. The form in which the hydrolysis stabilizer is added to the polyester can be that of dry liquid, absorbed by a carrier material.

Hydrolysis-resistant, multilayer polyester film with hydrolysis stabilizer

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.

Transparent, electrically conductive, coated polyester film, process for its production, and its use

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.
