This A-B-A Blown Film Extrusion Machine is basically a Blown Film Plant producing a THREE LAYER FILM but with the TWO EXTRUDER. It’s a result of a specially designed A-B-A Type Co-Ex Die which enables to produce a Three Layer Film with Two Extruder. Technically in A-B-A type film, the Outer and Inner layer will be of the same Polymer as being fed by the same extruder and a Middle Layer will be of a different Polymer which will be fed by a second extruder.
