<p>Transparent resin film having a low haze value (less than 10% as determined by ASTM D 1003) is produced by a process of inflation molding in an upward direction a resin composition comprising 100 parts by weight of a polybutylene terephthalate resin having an intrinsic viscosity IVa of at least 1.0, and between 15 and 45 parts by weight of a polycarbonate resin having an intrinsic viscosity IVb of at least 0.4. The ratio of melt viscosities eta A/ eta B, wherein eta A is the melt viscosity of the polybutylene terephthalate resin and eta B is the melt viscosity of the polycarbonate resin (each measured at a shear rate of 100<-><1> at 260 DEG C) is between 0.35 and 1.5.</p> |
