A holographic sealing member for a container comprises a heat actuated sealant or adhesive layer that secures the sealing member to a container, a metal foil sealing layer over and covering and adhesively bonded to the heat actuated sealant or adhesive layer, a holographic layer over and covering and adhesively bonding to the metal foil layer having an upper plastic layer and a lower embossed image layer, and a tab over and covering and adhesively bonded to the upper plastic layer that may be pulled to remove the tab and the plastic layer from a container, thereby exposing the lower embossed image layer which must then be perforated to gain access to the contents of the container.

1. A tamper-evident, tabbed sealing member for a container configured, upon sealing member removal, to leave a ring of material that remains bonded to a land area of a container rim, the tamper-evident, tabbed sealing member comprising: a heat actuated sealant or adhesive layer for securing the tamper-evident, tabbed sealing member to a land area of a container rim;a sealing layer bonded to the heat actuated sealant or adhesive layer, the sealing layer including a metal foil;a separation film between the sealing layer and the heat actuated sealant or adhesive layer, the separation film bonded to a lower surface of the sealing layer metal foil and including an upper polymer layer and a lower metal substrate;a splitting point for the tamper-evident, tabbed sealing member between the upper polymer layer and the lower metal substrate within the separation film so that the upper polymer layer can be separated from the lower metal substrate to form a tamper-evident peripheral ring of the lower metal substrate and the heat actuated sealant or adhesive layer that remains bonded to a land area of a container rim upon removal of the tamper-evident, tabbed sealing member from a container;a polyethylene or polypropylene or polyester foam or film layer bonded to an upper surface of the sealing layer; anda tab extending over at least a first portion of, but not bonded to the first portion of, the polyethylene or polypropylene or polyester foam or film layer where upward pulling of the tab, with the placement of the separation film below the sealing layer metal foil, causes the tamper-evident, tabbed sealing member to separate at the splitting point leaving a ring of the heat actuated sealant or adhesive layer and a ring of the lower metal substrate secured to a land area of a container rim to form the tamper-evident peripheral ring. 2. The tamper-evident, tabbed sealing member in accordance with claim 1, wherein the lower metal substrate of the separation film is aluminum. 3. The tamper-evident, tabbed sealing member in accordance with claim 1, wherein the heat actuated sealant or adhesive layer for securing the tamper-evident, tabbed sealing member to a container includes a medium density polyethylene. 4. The tamper-evident, tabbed sealing member in accordance with claim 1, wherein the tab is formed by a PET tab defining layer bonded to the tab but not bonded to the first portion of the polyethylene or polypropylene or polyester foam or film layer. 5. The tamper-evident, tabbed sealing member in accordance with claim 4, comprising an EVA film or foam layer bonded to both a second portion of the polyethylene or polypropylene or polyester foam or film layer not covered by the PET tab defining layer and also to the PET tab defining layer itself. 6. The tamper-evident, tabbed sealing member in accordance with claim 5, comprising a PET layer over and covering and bonded to the EVA film or foam layer. 7. The tamper-evident, tabbed sealing member in accordance with claim 6, wherein the polyethylene or polypropylene or polyester foam or film layer comprises a PET layer. 8. The tamper-evident, tabbed sealing member in accordance with claim 7, wherein the PET layer of the polyethylene or polypropylene or polyester foam or film layer is white. 9. A tamper-evident, tabbed sealing member for a container having a rim surrounding a container opening, the tamper-evident, tabbed sealing member comprising: a sealing portion having a periphery thereabout including a foil layer and a separation film bonded to a lower surface of the foil layer, the separation film including an upper polymer layer and a lower substrate; anda tab structure bonded to the sealing portion and comprising a tab such that the tab may be pulled to remove the tab structure and, with the placement of the separation film below the foil layer, the upper polymer layer of the separation film from a container rim while leaving peripheral ring portions of the lower substrate bonded to a land area of a container rim so that a tamper-evident ring of the lower substrate is undisturbed by the removal of the tab structure and the upper polymer layer. 10. The tamper-evident, tabbed sealing member of claim 9, wherein the tab lies wholly within the periphery of the sealing portion. 11. The tamper-evident, tabbed sealing member of claim 9, wherein the separation film has a splitting point between the upper polymer layer and the lower substrate such that upon pulling of the tab, the separation film separates at the splitting point corresponding to a land area of a container rim. 12. The tamper-evident, tabbed sealing member of claim 9, wherein the tamper-evident, tabbed sealing member includes a heat actuated sealant or adhesive layer for bonding to a rim of a container. 13. The tamper-evident, tabbed sealing member of claim 9, wherein the strength of a bond between the tab structure and the upper polymer layer of the separation film is greater than the strength of a bond between the upper polymer layer and the lower substrate of the separation film. 14. The tamper-evident, tabbed sealing member of claim 9, wherein the sealing portion further includes a polyethylene or polypropylene or polyester foam or film layer covering the foil layer. 15. The tamper-evident, tabbed sealing member of claim 9, wherein the sealing portion further includes a foam layer covering the foil layer and a polyethylene, polypropylene or polyester film layer above the foam layer. 16. The tamper-evident, tabbed sealing member of claim 9, wherein the lower substrate includes a metal substrate.
