Layer multiplication co-extrusion is a process of substantial academic interest and achievement and one of proven industrial application. The industrial adoption of the process has primarily been in the realm of specialty and advanced products in film geometries for applications such as UV control and strength in windows, decorative coatings for marketing and aesthetics, and barrier applications for control of packaging environments. Recently, our group expanded the processing realm into annular geometries and has begun to demonstrate the functional application of such products. To date, novel layered foam tubing has been processed that could show potential strength improvements to light weight piping. Additionally, mechanical strength improvements of layered pipes having weld lines have been demonstrated with the implementation of the technology of die head rotation in conjunction with layer multiplication. Most recently, the translation of this technology to the area of extrusion blow molding has been accomplished by the creation of the first ever bottles containing 131 layers.
