摘要:
The invention relates to a single- or multilayer, biaxially oriented film based on a crystallizable polyester and comprising at least one primary stabilizer for inhibiting oxidative degradation. The crystallizable polyester comprises from 100 to 10 000 ppm of primary stabilizer in covalently bonded form. The invention further relates to a process for producing the film.
