Recent developments in the area of multi-layer co-extrusion have led to the ability to produce annular structures with high numbers of very thin layers. The burst pressure of these pipe structures as well as blow molding applications were investigated. It was observed that die head rotation can have impacts on the mechanical properties of these structures due to the elimination of weld lines, as well as biaxially orientation effects in the annular structures. It was also observed that following the elimination of the weld lines, the burst strength changes, possibly due to the biaxial orientation effects at higher rotation speeds. With the production of annular structures, the application of blow molding was examined. Samples were blow molded to see the effects of the blow molding process on the layer uniformity.
