PROCESS FOR PRODUCING PERMEATION RESISTANT CONTAINER

摘要

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 additive s including lower alkanols and ethers consistently and reliably. The process is related to a treatment of plastic containers in a controlled manner with fluorine contain ing 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 exposur e to a fluorination gas. After the fluorination, the container is quenched by expos ing the container to a fluorine reactive gas to react with the fluorine, thereby con verting the fluorine to a less reactive gas.
