Abstract: A rigid single- or multilayer non-oriented or mono- or biaxially oriented film in which at least one layer comprises a cycloolefin copolymer, wherein the cycloolefin copolymer has an intrinsic E modulus (E i) which has the following dependence on the glass transition temperature T g: E i = (0.0025 [GPa/.degree.C] .times. T g [.degree.C]) + B [GPa] where B = 2.93-3.19 and T g is the glass transition temperature.
