The blown film process is used to produce a wide variety of products, ranging from simple monolayer films for bags to very complex multilayer structures used in food packaging. Multilayer film structures may be made by blown film coextrusion and combines two or more molten polymer layers.

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.
