PCT No. PCT/EP97/05208 Sec. 371 Date Jun. 30, 1999 Sec. 102(e) Date Jun. 30, 1999 PCT Filed Sep. 23, 1997 PCT Pub. No. WO98/13415 PCT Pub. Date Apr. 2, 1998The invention relates to a biaxially oriented polyester film having one or more layers and a thickness of </=10 mu m, where the mechanical consolidation coefficient MC, given by the following equation, lies within the ranges given below: MC here is >/=-2, preferably >0 and in particular >0.5, particularly preferably >/=1, and is </=50, preferably </=30 and particularly preferably <5 S200TD is the transverse shrinkage in % at 200 DEG C. after 15 min. S200MD is the longitudinal shrinkage in % at 200 DEG C. after 15 min. T2% is the temperature in DEG C. at which the film elongates by 2% under a constant tension of 5 N/mm2. ETD is the transverse modulus of elasticity (tensile modulus) at room temperature (21 DEG C.) in N/mm2.
