Biaxial stretch blow moulding is a process for producing a plastic container from a preform or parison that is stretched in both circumferential and axial direction when the preform is blown into its desired container shape [Lee90]. It is well established for the large scale production of high quality PET containers with excellent mechanical and optical properties [THG06]. These properties lead to an increasing market share of stretch blow moulded containers in the field of packaging, resulting in steadily increasing sales.
