FIELD: chemistry.SUBSTANCE: invention relates to a multilayer film composite, an identification smart card, an identification document, a personal data medium etc, having a multilayer film composite, use of said multilayer film composite, production thereof and a polycarbonate or copolycarbonate composition. The multilayer film composite has at least one layer of polycarbonate or copolycarbonate and is characterised by that the polycarbonate or copolycarbonate further contains one or more additives selected from a group comprising petaerythritol tetrastearate, glycerol monostearate, propanediol stearate, stearyl stearate and mixtures of said compounds. Total concentration of the additives selected from said group ranges from 2.1 to 6% with respect to the weight of the composition.EFFECT: obtaining a film for producing multilayer systems, having the necessary level of mechanical properties and characterised by a higher layering suitability compared to prior art, high layering adhesion and improved processing properties.7 cl, 1 tbl, 1 dwg, 4 ex |
