The Coextrusion technology is the simultaneous extrusion of two or more polymers to get a multilayer structure. This technological variant allows to manufacture a plastic container with several layers (multilayer), thanks to the use of several extruders, containing one of them a material that has barrier properties.

At ALCION PACKAGING SOLUTIONS we produce multilayer barrier packaging with 4 to 6 layers, depending on the need for preservation and protection of the contained product, using either EVOH or PA as barrier materials. The efficiency of multilayer plastic containers manufactured by MULTILAYER COEXTRUSION BLOW MOULDING with EVOH barrier layer, for example, stands out for using a material that has a high degree of oxygen impermeability, even in very low thicknesses, in low humidity conditions.
