Abstract

The invention concerns transparent, flame retardant, thermoformable, UV-stabilized, single layered or multilayered films, containing a cristallizable thermoplastic material, preferably polyethyleneterephthalate, at least one flame retarding agent and a UV stabilizer as main components. Said films are characterized by good stretchability, thermoformability and good optical and mechanical properties, which makes them and the shaped bodies made from said films suitable for both inner and outer applications.
