We have studied the anisotropy and homogeneity of Polyamide films that were prepared using different stretching techniques (uniaxial, sequential biaxial, simultaneous biaxial and "double bubble"). Structural changes concerning crystallinity and orientation of crystallites are evaluated using X-ray measurements (SAXS, pole figures). We show how the microstructure correlates with the anisotropy of properties, that are sensitive to the molecular orientation (microwave permittivity and infrared absorption). We conclude with a quantitative comparison of the above industrial production techniques.
