Three multi-layer blown film extrusion (also known as blown film co-extrusion) is a process of simultaneously extruding in molten stage various kinds of polymers which adhere to each other through a common die to form an integral film of unique strength and barrier properties. The selection of layers depends upon end properties required as well as items to be packed. Multilayer co-extrusion of PE, PA, TIE, EVOH and other resins can be used for vacuum packaging of dairy products, jams, meat products, etc.
Our multi-layer co-extruded film has both cold water quenching process and air blown process technology, which provides excellent optical appearance and mechanical properties. Customized structure is available like PA/PE, PA/PP, PA/EVOH/PE etc.
