1. A two-piece sealing member for a container having an opening surrounded by a rim, the sealing member comprising: a liner portion and a seal, the liner portion and the seal effective to be separable after induction heating so that the liner portion remains in a cap of a container and the seal rema
1. A two-piece sealing member for a container having an opening surrounded by a rim, the sealing member comprising: a liner portion and a seal, the liner portion and the seal effective to be separable after induction heating so that the liner portion remains in a cap of a container and the seal remains adhered to a rim of a container;a wax layer on a lower surface of the liner portion releasably bonding the liner portion to an upper surface of the seal;a tab structure of the seal defining a tab lying wholly within the circumference of the sealing member and extending part way across the seal, the tab can be pulled, in use, to remove the seal from a container;a lower laminate having a top layer under the tab structure and a heat sealable layer effective to secure the seal to a container during induction sealing; andan optical security component located under the tab, the optical security component and the tab each of a size and configuration effective to protect the optical security component from contact with the wax during induction heating and arranged so that the optical security component is visible upon pivoting of the tab,wherein the optical security component has an optical density after induction sealing within about 10 percent of an optical density prior to induction sealing. 2. The two-piece sealing member of claim 1, wherein the optical security component is bonded to a first portion of the top layer. 3. The two-piece sealing member of claim 1, wherein the optical security component is bonded to the tab. 4. The two-piece sealing member of claim 1, further comprising a polymer layer above the top layer and under the tab structure and wherein the optical security component is bonded to the polymer layer. 5. The two-piece sealing member of claim 4, wherein the polymer layer is selected from the group consisting of a non-foamed polymer layer and a foamed polymer layer. 6. The two-piece sealing member of claim 1, wherein the optical security component includes a security feature selected from the group consisting of a holographic component, optically variable ink, color shifting ink, interference films, and combinations of holographic components and optically variable ink and color shifting ink and interference films. 7. The two-piece sealing member of claim 1, wherein the optical security component includes a holographic portion with an embossed image layer having a plastic film layer bonded to a first surface of the image layer and a metal layer on a second surface of the embossed image layer. 8. The two-piece sealing member of claim 1, wherein the optical security component is bonded to both the tab stock and the membrane layer and includes a splitting point therein effective to form the tab upon the optical security component splitting apart at the splitting point. 9. A two-piece sealing member for a container having an opening surrounded by a rim, the sealing member comprising: a liner portion and a seal, the liner portion and the seal effective to be separable after induction heating so that the liner portion remains in a cap of a container and the seal remains adhered to a rim of a container;a wax layer on a lower surface of the liner portion releasably bonding the liner portion to an upper surface of the seal;a tab structure of the seal defining a tab lying wholly within the circumference of the sealing member and extending part way across the seal, the tab can be pulled, in use, to remove the seal from a container;a lower laminate having a top layer under the tab structure and a heat sealable layer effective to secure the seal to a container during induction sealing; andan optical security component located under the tab, the optical security component formed by at least one layer extending only part way across the seal, the optical security component being smaller than the tab such that the tab is effective to protect the optical security component from contact with the wax during induction heating. 10. The two-piece sealing member of claim 9, wherein the optical security component is bonded to a first portion of the top layer. 11. The two-piece sealing member of claim 9, wherein the optical security component is bonded to the tab. 12. The two-piece sealing member of claim 9, further comprising a polymer layer above the top layer and under the tab structure and wherein the optical security component is bonded to the polymer layer. 13. The two-piece sealing member of claim 12, wherein the polymer layer is selected from the group consisting of a non-foamed polymer layer and a foamed polymer layer. 14. The two-piece sealing member of claim 9, wherein the optical security component includes a security feature selected from the group consisting of a holographic component, optically variable ink, color shifting ink, interference films, and combinations of holographic components and optically variable ink and color shifting ink and interference films. 15. The two-piece sealing member of claim 9, wherein the optical security component includes a holographic portion with an embossed image layer having a plastic film layer bonded to a first surface of the image layer and a metal layer on a second surface of the embossed image layer. 16. The two-piece sealing member of claim 9, wherein the optical security component has an optical density after induction sealing within about 10 percent of an optical density prior to induction sealing. 17. The two-piece sealing member of claim 9, wherein the optical security component is bonded to both the tab stock and the membrane layer and includes a splitting point therein effective to form the tab upon the optical security component splitting apart at the splitting point. 18. A two-piece sealing member for a container having an opening surrounded by a rim, the sealing member comprising: a liner portion and a seal, the liner portion and the seal effective to be separable after induction heating so that the liner portion remains in a cap of a container and the seal remains adhered to a rim of a container;a wax layer on a lower surface of the liner portion releasably bonding the liner portion to an upper surface of the seal;a tab structure of the seal defining a tab lying wholly within the circumference of the sealing member and extending part way across the seal, the tab can be pulled, in use, to remove the seal from a container;a lower laminate having a top layer under the tab structure and a heat sealable layer effective to secure the seal to a container during induction sealing; andan optical security component located under the tab and being visible through the tab, the optical security component and the tab each of a size and configuration effective to protect the optical security component from contact with the wax during induction heating,wherein the optical security component has an optical density after induction sealing within about 10 percent of an optical density prior to induction sealing. 19. The two-piece sealing member of claim 18, wherein the optical security component is bonded to a first portion of the top layer. 20. The two-piece sealing member of claim 18, wherein the optical security component is bonded to the tab. 21. The two-piece sealing member of claim 18, further comprising a polymer layer above the top layer and under the tab structure and wherein the optical security component is bonded to the polymer layer. 22. The two-piece sealing member of claim 21, wherein the polymer layer is selected from the group consisting of a non-foamed polymer layer and a foamed polymer layer. 23. The two-piece sealing member of claim 18, wherein the optical security component includes a security feature selected from the group consisting of a holographic component, optically variable ink, color shifting ink, interference films, and combinations of holographic components and optically variable ink and color shifting ink and interference films. 24. The two-piece sealing member of claim 18, wherein the optical security component includes a holographic portion with an embossed image layer having a plastic film layer bonded to a first surface of the image layer and a metal layer on a second surface of the embossed image layer. 25. The two-piece sealing member of claim 18, wherein the optical security component is bonded to both the tab stock and the membrane layer and includes a splitting point therein effective to form the tab upon the optical security component splitting apart at the splitting point.
