Zusammenfassung:The present invention is directed to a thin packaging film made out of a thermoplastic material with anti-UV properties, characterized in that its composition further comprises a combination of at least one organic compound with at least one inorganic UV-absorbent compound, for improved barrier against UV rays, and improved transparency. Preferably, the organic compound is a benzotriazole, and the inorganic compound is micronized zinc oxide. More preferably, the material for the film further comprises a binder compound, for example a benzophenone, in order to improve the compatibility between the organic component and the base-resin. Preferably, the film thickness is below 80 mu m, more preferably below 35 mu m.
