Introduction to Coextrusion Systems, 2002 PLACE Conference Proceedings
Coextrusion is defined as a process in which two or more polymers are extruder and joined together in a feedblock
or die to form a single structure with multiple layers. Coextrusion applications can range from as simple as a striped
plastic beverage straw, to as complex as structures with nearly a thousand layers. The application of coextrusion is
based on the viscoelastic properties of the materials combined to produce the composite structure. In both simple
and complex structures, the viscosity and the elastic properties of each of the components must be considered to
insure success.
