The supermolecular structure of blown HDPE films, which were obtained by a combination of film blowing under a very low blowup ratio and slow takeoff velocity with subsequent uniaxial drawing, is characterized using WAXS texture and profile analysis, EM and mechanical investigations. Samples with low uniaxial drawing ratios (λ ≲ 1.5) contain low stress crystalline and transcrystalline material and show an a-texture, while samples with higher uniaxial drawing ratios only consist of high stress crystalline material and show a c-texture. With one exception the results of texture investigations can be related to the results of the mechanical investigations.
