A sealing cover has an upper layer of plastic film substantially impervious to moisture and bacteria. A second layer of metal foil film is bonded to the plastic layer with a layer of adhesive or by extruding the plastic onto the second layer. An additional layer of adhesive material is bonded to the second layer for adhering to a carrier liner in packaging the seal and engaging the container top in resealing the container upon removal from the carrier. Upon removal of the sealing cover from a container, telltale strips of the cover are left in engagement with the container to indicate the seal has been removed. In another embodiment, a layer of metal foil is laminated between two layers of plastic film. Slits may be formed in the cover to promote its tearing to leave telltale sealing strips on the container upon removal of the cover. In another embodiment, a single layer of metal foil substantially impervious to moisture and bacteria includes a layer of adhesive material for an adhesive-coated surface for resealing the top of a container.

A flexible sealing cover for resealing a port of a pharmaceutical container, comprising: a layer of flexible film forming a cover region of the sealing cover and being substantially impervious to moisture and bacteria, said film being plastically deformable under stress; a pull tab region extending from said cover region; an area of adhesive material bonded to a major surface of said layer of flexible film for providing an adhesive surface of the cover and pull tab regions; means forming a first non-adhesive region within said area of adhesive material of said cover region and a second non-adhesive region within said area of adhesive material of said pull tab region; and means for tamper proofing the seal whereby the seal is destroyed upon removal from the port of the container, thereby leaving a telltale strip of material on the port of the container and preventing reuse of the seal.
