Milliken & Company has announced new pharmaceutical packaging technology that it claims generates superior barrier quality in over-the-counter bottles.

Milliken said that its Hyperform® HPN-20E agent alters HDPE resins in a way that improves moisture and oxygen barrier performance in bottles by 30 percent. The agent changes crystal orientation, creating a maze that inhibits the passage of moisture and oxygen at a molecular level.

Enhanced HDPE resin is already used in injection/blow-molding (IBM) to produce quality bottles. The company said that if the agent is used during this process, then IBM will drive even greater sustainability and quality in over-the-counter bottles. If the agent enhances IBM, then manufacturers could theoretically look forward to faster cycle times and thinner pharmaceutical and nutraceutical bottle designs. This would require less plastic during manufacturing, which in turn would yield fewer processing emissions.
