Web11.2.2.2 Blown Film. The blown-film process involves extruding a relatively thick tube, which is then expanded or blown by internal air pressure to produce a relatively thin film. The tube can be collapsed to form double-layer layflat film or can be slit to make one or two single-layer film webs.
WebDec 5, 2012 · Extrusion ratio equalled 20,2. At the beginning, calculations of indirect extrusion for flat dies were performed, analysing the influence of holes' distribution on quality of obtained products. Webextrusion [2] can induce the large contact pressure and new surface generation. Meanwhile, the load of forward extrusion and cup height ratio of double cup extrusion are sensitive to friction. In upsetting-sliding test [3] friction coefficient is calculated starting from the tangential and normal forces of
