Inthisprocess the polymer, melt is extruded through an annular die to a rising continuous tube which is cooled by an air. Ring and is simultaneously axially stretched and circumferentially ring and is simultaneously axiall stretched and circumferentially. Inflated by the, take-up force F and the, internal bubble pressure respectively until the freezeline,,,, height L is reached. (see Fig1). Consequently with the, help of thecollapsing frames and, nip roll the solidified film bubble is changed from. The bubble shape to alay-flat tube of film. The obtained biaxilly oriented polymer film has mechanical physical and optical,,, Properties (e.g.tensile strength tear, seal, resistance heat characteristic transparency), that are desirable in daily used. Products such as, carrierbags wrapping foils,,, films garbage medical or as electrolytic membranes (where polylefines PS PVC,,, PA respresents typical film blowing poylmers).
