INTRODUCTION
For many years, the dependence of mechanical properties on the morphological structure of the polymer has been the subject of research works. Many investigations have been reported concerning complex relationships among processing, structure, and properties in film blowing [1-4]. The development of molecular orientation and morphology in blown films has been investigated extensively in recent years [5-14]. Numerous studies focused on the influence of processing parameters on mechanical behavior of blown film [15-18]. Some researchers have attempted to correlate the mechanical properties of blown films with the kinematics and dynamics of the process ...
