ABSTRACT:
In a blow molding process in which a parison is blown with a blowing gas containing a reactive gas component capable of reacting with the inner walls of the parison, the blowing gas is removed from the resulting blown article with a purging gas and stored for reuse. The mixture of blowing and purging gases in a reserve tank or other suitable means is adjusted to a certain level of pressure and reactive gas concentration and then recycled as the blowing gas in a subsequent blow molding step. The resulting blown articles from this process have improved properties, e.g. improved impermeability against non-polar solvents when fluorine is the reactive gas.
