Abstract: The present invention provides methods for reducing extractables from plastic articles made from recycled plastic. The method includes the steps of: (a) providing a plastic article in a chamber; and (b) providing a fluorination gas in the chamber, thereby exposing the plastic article to the fluorination gas. The method results in the reduction of the extractables from the plastic article.
Abstract: A multi-layer article includes a first layer that includes a first polyolefin resin powder and a second polyolefin resin powder that has been treated with a fluorine reaction gas. The multi-layer article also includes a second layer adhered to the first layer.

Abstract: A method for removing perfluorinated compounds from a fluoropolymer material is provided. The method includes the steps of: (a) providing the fluoropolymer material in a chamber; (b) providing an anaerobic environment in the chamber; and (c) providing a fluorination gas in the chamber, thereby exposing the fluoropolymer material to the fluorination gas. The method results in the removal the perfluorinated compounds from the fluoropolymer material.

Abstract: A method for the direct fluorination of plastics and articles made from plastics is presented. The novel method includes ensuring extremely low oxygen and moisture content in the chamber before the primary fluorination step, ramping the fluorine concentration during the fluorination step, and providing a quenching step for improved shelf-life. Containers processed by the novel method demonstrate a marked improvement in barrier properties for organic solutions.
