Abstract
A sealing composition for a container closure comprises a polymeric matrix material and its oxygen permeability is reduced by incorporating ethylene vinyl alcohol polymer into the composition. The composition can be in fluid or meltable form ready for application to a closure or it can be present as a deposit on the closure, for instance a gasket around the closure.
