AMORPHOUS, TRANSPARENT, THERMOFORMABLE FILM WHICH ABSORBS UV-LIGHT, A METHOD FOR THE PRODUCTION THEREOF AND THE USE OF THE SAME

摘要

The invention relates to an amorphous, transparent, UV-stable barrier film consisting of a crystallisable thermoplastic, whose thickness ranges between 30 and 1000 mu m. The film contains at least one barrier layer against gases and a UV-absorber which can be dissolved in the thermoplastic. Said film is characterised by excellent optical characteristics, cost-effective thermoforming properties and in particular, by the absorption of short-wave UV-light in the wavelength range below 380 nm. The invention also relates to a method for producing said film and to the use thereof.
