Abstract:
An elastomeric article for sealing a container includes an elastomeric body having an external sidewall surface and an external crown surface and a first fluoropolymer film layer having an internal surface and an external surface. The internal surface of the first fluoropolymer film layer is laminated to an entirety of the external sidewall and crown surfaces of the elastomeric body. The external crown surface of the first fluoropolymer film layer includes a drug contact surface configured to contact a drug contained in the container and the external sidewall surface including a sealing surface for contacting an interior surface of the container. The external surface of the first fluoropolymer film layer is substantially free of striations.
