The rheological behavior and properties of polymers fluid are significantly concerned with their internal structure therefore its have been experimentally and numerically investigated for many of industry applications. This article of research studies the characterization of (ecovio F Film C2203) biopolymer due to their characteristics and importance in different fields of health and environment. Two type of rheometers instruments have been used at different temperatures range (140 - 220 C) to describe the rheological properties of the (ecovio F Film C2203) biopolymer melts with various investigating mechanisms. The results were compared with the linear results of oscillatory measurements and non-linear results of steady-state method which provide the storage and the loss modulus of the (ecovio F Film C2203) melting, and given the model of Cox-Merz. Likewise, in the measuring of a viscosity for the (ecovio F Film C2203) at the higher shear rate, particularly at the excess temperature, one of the master problems was in the using of a capillary rheometer, because of the long chains of a molecule which led to the high viscosity.
