    Abstract: The present invention provides methods for reducing extractables from plastic articles and improving barrier properties of such plastic articles. The method includes the steps of: (a) providing a plastic article in a chamber; and (b) providing a fluorination gas and a second gas, such as oxygen or another halogen other than fluorine, in a chamber, thereby exposing the plastic article to the fluorination gas and the second gas. The method produces a treated plastic article that is both low in extractable components and suitable for use in packaging formulations containing an organic ingredient.

    Abstract: Hollow body made of plastic having a fluorinated inner surface according to the present invention is characterized in that in one or more defined regions of the inner surface, the fluorine occupancy deviates from the mean fluorine occupancy by at least ±10%.Furthermore, a method for the production of a hollow body made of plastic having a fluorinated inner surface is presented, in which, for the formation of fluorocarbon and hydrofluorocarbon compounds, the inner surface is exposed to the action of a defined amount of a fluorine-containing treatment gas and the hollow body is thermostatted on its outside so that the temperature in one or more defined regions of the outside is at least ±2° C. above/below the mean temperature of the outside.

    Abstract: The gas-phase fluorination of plastic articles is effected in a reaction chamber 1 into which the plastic articles to be fluorinated are introduced. The gas-phase fluorination is effected at normal or atmospheric ambient pressure of about 1 kPa in the reaction chamber. The gas-phase fluorination can be carried out statically or dynamically. The flushing carried out before the gas-phase fluorination for complete or partial removal of atmospheric oxygen from the reaction chamber 1 can also be effected at atmospheric pressure in the reaction chamber. The reaction chamber 1 is equipped with a cover 2 and metering valves V0, V1, V2 for air, inert gas and gas mixture comprising fluorine and one or more inert gases are present on the entrance side of the reaction chamber, which is not vacuum-tight and hence also cannot be evacuated. The metering valves are connected to the reaction chamber 1 via a flow meter 4. A release valve V3 and a flow-through/shut-off valve V4 are arranged in an exhaust gas line 8 of the reaction chamber 1.
