Abstract
The present invention discloses an improved process for producing plastic containers with excellent resistance to permeation by solvents such as hydrocarbons, hydrocarbon fuels, and hydrocarbon fuels with organic additives including lower alkanols and ethers consistently and reliably. The process is related to a treatment of plastic containers in a controlled manner with fluorine containing gases while blow molding them. In the process of the present invention, an article of manufacture, a container, is formed and subjected to fluorination by exposure to a fluorination gas. After the fluorination, the container is quenched by exposing the container to a fluorine reactive gas to react with the fluorine, thereby converting the fluorine to a less reactive gas.
