The invention relates to a 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. The form in which the hydrolysis stabilizer is added to the polyester is that of dry liquid, absorbed by a carrier material.

摘要:
This invention relates to a white, biaxially oriented polyester film, preferably formed of PET, with a base layer and with at least one outer layer. The base layer includes a concentration of from 3 to 15% by weight of a whitening pigment, and the outer layer includes a concentration of from 2 to 15% by weight of a whitening pigment and from 0.01 to 2% by weight of an antiblocking agent. The antiblocking agent has a median particle diameter of from 2 to 8 μm. Optionally, at least one surface of the film has a functional coating. The film is particularly suitable as lid film for food-or-drink containers.

The invention relates to biaxially oriented polyester films that include a chain extender in addition to the polyester. Such films find use in all applications typical of biaxially oriented polyester films, especially in outdoor films, as a ribbon cable, as a backside laminate of solar modules and in electrical insulation applications.

摘要:
A polyester film with a high transparency, such as a transparency of from 70 to 99.5%, is provided that includes barium sulfate particles whose median particle size is from 0.7 to 7 μm. The barium sulfate particles have an inorganic coating formed from oxides, mixed oxides, or a mixture of oxides of Si, Al, Sn, Fe, In, and/or Sb. The coating makes the barium sulfate particles more compatible with the polyester matrix, thereby minimizing the haze of the film. Preference is given to mixed oxides of SiO2 and Al2O3, and PET is the preferred polyester.
