The present invention is directed to a thermoplastic additive containing aluminum stearate and polyvinylidine fluoride which when added to thermoplastics such as polyethylene inhibits and reduces permeation of fluids stored within containers composed of the thermoplastic. The software-managed hardware profiles are decoupled from the signal processing functionality of the software. Thereafter, the substrate is annealed in a nitrogen ambient at such a temperature as activating the dopant introduced.
