1. A method for manufacturing a sealable container closure, comprising: providing a first mold section, a second mold section and a third mold section;mating the first mold section with the second mold section to form a first cavity area;injecting a fusible polymeric material into the first cavity area to form a fusible ring having a shelf and at least one passage between an inner periphery and an outer periphery of the fusible ring;removing the second mold section from the first mold section after the fusible polymeric material has been injected into the first cavity area to form the fusible ring;subsequently placing a panel on the shelf of the fusible ring;subsequently mating the third mold section with the first mold section to form a second cavity area within which the fusible ring is located; andsubsequently injecting a thermoplastic polymeric material into the second cavity area to form a frame, wherein a first segment of the frame is within the inner periphery of the fusible ring, a second segment of the frame is outside the outer periphery of the fusible ring, and a third segment of the frame extends through the passage of the fusible ring between the first and second segments of the frame and wherein the panel, frame and fusible ring form the closure. 2. The method according to claim 1 wherein the fusible polymeric material is an electromagnetic material. 3. The method according to claim 1 wherein the fusible polymeric material is an oxygen scavenger. 4. The method according to claim 1 wherein the thermoplastic polymeric material includes one or more compounds selected from the group consisting of fumed silica, glass micro-spheres, talc, nano-clay, mica, calcium carbonate, iron powder, nylon, and EVOH. 5. The method of claim 1 wherein the panel includes a grip means for removing at least a portion of the panel. 6. The method of claim 5 wherein the grip means is a pull tab which extends from the panel. 7. The method of claim 5 wherein the grip means is a ring pull which is attached to the surface of the panel. 8. A method for manufacturing a sealable container closure, comprising: providing a first mold section, a second mold section and a third mold section;mating the first mold section with the second mold section to form a first cavity area;injecting a fusible polymeric material into the first cavity area to form a fusible ring having an inner periphery, an outer periphery and at least one passage extending between the inner periphery and the outer periphery of the fusible ring;removing the second mold section from the first mold section after the fusible polymeric material has been injected into the first cavity area to form the fusible ring;subsequently placing a panel on the fusible ring;subsequently mating the third mold section with the first mold section to form a second cavity area within which the fusible ring is located; andsubsequently injecting a thermoplastic polymeric material into the second cavity area to form a frame, wherein a first segment of the frame is within the inner periphery of the fusible ring, a second segment of the frame is outside the outer periphery of the fusible ring, and a third segment of the frame extends through the passage of the fusible ring between the first and second segments of the frame, wherein the panel, the frame and the fusible ring form the closure. 9. A method for manufacturing a sealable container closure, comprising: providing a first mold section, a second mold section and a third mold section;mating the first mold section with the second mold section to form a first cavity area;injecting a fusible polymeric material into the first cavity area to form a fusible ring having an inner periphery, an outer periphery and at least one passage extending between the inner periphery and the outer periphery of the fusible ring, wherein the inner periphery of the fusible ring defines the boundary of an open inner area;removing the second mold section from the first mold section after the fusible polymeric material has been injected into the first cavity area to form the fusible ring;positioning a closure panel within the open inner area of the fusible ring;subsequently mating the third mold section with the first mold section to form a second cavity area within which the fusible ring and the closure panel are located; andsubsequently injecting a thermoplastic polymeric material into the second cavity area to form a frame, wherein a first segment of the frame is within the inner periphery of the fusible ring, a second segment of the frame is outside the outer periphery of the fusible ring, and a third segment of the frame extends through the passage of the fusible ring between the first and second segments of the frame, wherein at least the first segment of the frame is formed around the closure panel, and wherein the frame, the closure panel and the fusible ring form the closure. 10. The method of claim 9, wherein the step of positioning the closure panel within the open inner area of the fusible ring is carried out by placing an edge of the closure panel on the fusible ring. 11. The method of claim 10, wherein the step of placing the edge of the closure panel on the fusible ring is carried out by placing the edge of the closure panel on a shelf area defined by the fusible ring.
