Abstract
A plastic closure that includes a cap having a base with a peripheral skirt defining a cap interior and threads on the skirt for securing the closure to a container. A liner is secured to the interior of the cap, preferably by compression molding in situ. The liner preferably consists essentially of a blend of matrix polymer material, particulate barrier polymer material and compatibilizer material. The heat and pressure of compression forms the particles of barrier polymer material into platelets that are oriented essentially parallel to the plane of the closure base.
