Abstract

See full text

A flexible plastic sealing cover has a container cover area and pull-tab area. In one embodiment, an upper layer of plastic film is substantially impervious to moisture and bacteria. An orientated plastic film layer is bonded to the upper layer with a layer of adhesive, such that the orientated plastic layer promotes tearing when the cover is removed with the pull-tab. An adhesive material is bonded to the layer of orientated plastic film for engaging and sealing the container top of a IV solution container. In removing the sealing cover from a container, telltale strips of the cover are left in engagement with the container to indicate the sterilized seal has been removed. In another embodiment, a single layer of plastic film substantially impervious to moisture and bacteria is bonded with a layer of adhesive material. Slits may be formed in the plastic layer to promote its separation to leave telltale sealing strips on the container upon removal of the cover.
