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.
