Abstract: An extruded PET parison includes a first extruded polymer comprising PET, and a second extruded polymer comprising PET. In embodiments, the first extruded polymer and the second extruded polymer are co-extruded, and the first extruded polymer has an intrinsic viscosity that is higher that the intrinsic viscosity of the second extruded polymer. A monolayer embodiment is also disclosed. In embodiments, a monolayer extruded PET container is comprised of bottle grade PET resin that has been solid stated and may have an IV from about 0.96 to about 1.4.
