Abstract
A container having a barrier layer is provided. The container may be of thermoplastic and the barrier may inhibit materials from leaching from the thermoplastic material or from extraction of compounds from medicants by the thermoplastic. A process is also described that allows for molding thin barrier layers as container lines and for forming thermoplastic containers with barrier liners.
