Abstract:
A multilayer film for medical purposes is proposed, with one or two external layers, wherein the external layers contain: a first polyalphaolefin; a first thermoplastic elastomer with a melt viscosity of a melt flow index according to ISO 1133 of from 0.001 to 6 g/10 min at 230° C., 2.16 kg; and a second thermoplastic elastomer with a high melt viscosity not measurable according to ISO 1133 which is higher than the melt viscosity of the first thermoplastic elastomer.
