The article describes the influance of the microstructure and environment conditions on the mechanical properties of PET material. From the microskopic point of view, mechanical and thermal properties of PET material have the biggest influance on orientation and crystallization processes of material. From the macroskopic point of view mechanical properties can be described by parameters derived from strees-strain mechanical answers (e.g. from viscosity testing and/or from uniaxial and biaxial stretching tests). Macroscopic mechanical properties average the material microstructure answer to the external force. The article desribes the mechanical properties of PET taking into account the influance of temperature, strain, strain rate, molecular weight and method of deformation. The discussion was prepared on the basis of the collected litarature data.
