Abstract
The present invention relates to a single or multilayer biaxially oriented film having a thickness of ≦12 &mgr;m, in which T,(TD) is ≧160° C., S 200 (TD) is ≦5%, S 200 (MD) is 2-5%, the shrinkage force ratio N,220/N,160 is ≧4.5; the film fixing peak is ≧210° C.; the film density is 1.39-1.41 g/cm,, and T,(TD) is the temperature at which the transverse shrinkage begins, S 200 (TD) is the shrinkage in the transverse direction (in %) at 200° C., S 200 (MD) is the shrinkage in the machine direction (in %) at 200° C., N,220 is the shrinkage force (in N) at 220° C. and N,160 is the shrinkage force (in N) at 160° C. in the transverse direction. The invention also relates to a method for forming the film.
