Abstract
A method for applying a PVDC polymer coating to the outside of a PET parison includes deionizing the surface of the parison, dipping the parison into an aqueous PVDC dispersion, withdrawing the parison at a controlled rate to prevent slubbing of the polymer coating, and drying the coating by exposure to desiccated air. The method dramatically reduces the energy requirements for coating operations yet produces a finished biaxially oriented PET container having superior gas barrier characteristics.
