摘要： A plastic closure that comprises a cap having a base with a peripheral skirt defining the 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 being compression molded in situ on the base. The liner consists essentially of a multiplicity of alternating layers of a matrix polymer material such as EVA and a barrier material such as EVOH to resist transmission of gas, water vapor and/or flavorants through the liner. The matrix polymer material preferably is preblended with a compatibilizer material such as a maleic anhydride grafted polymer that ties the matrix polymer material to the barrier material.

摘要： 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.
