Nearly 50 percent of applications for plastics & resins products are seen in making different types of flexible and rigid applications, especially types requiring a co-extrusion process. Co-extrusion can be useful in blown film, blow molding, and extrusion coating processes, and the distinct advantage of co-extrusion is that each ply of the structure achieves a different desired characteristic, such as stiffness, heat-sealability, H2O-impermeability or resistance to other environmental effects, all of which would be impossible to attain with any single material.
Manufacturers can select EVOH products with various levels of ethylene content for fabrication of barrier packaging products via fabrication processes such as blown or cast co-extrusion, co-extrusion lamination, co-extrusion coating and coextrusion blow molding. These various processes are then used to form flexible packaging, rigid packaging, sheet for thermoforming and tubes.
