Estimating the term…
An container sealing material suitable for sealing a container comprises a liner sheet (liner), a sealant sheet, and an interlayer portion (interlayer) bound between the liner and the sealant sheet by individual layers of wax. The material has a closure-contacting surface and a heat-sealable surface. At least one of the surfaces of the liner and the interlayer that contacts a layer of wax is capable of absorbing liquid wax when the layer of wax is melted. At least one of the surfaces of the sealant sheet and interlayer which contacts a layer of wax is capable of absorbing liquid wax when the layer of wax is melted. The liner and the sealant sheet each release from the interlayer when sufficient heat is applied to the container sealing material to melt the layers of wax. The interlayer can include printed matter visible on one or both of its surfaces (e.g., a logo, proof-of-purchase indicator, and the like). The printed matter can include promotional indica for a product, a service, a game and the like. Accordingly, the container sealing material provides a means for including a promotional token, such as a redeemable coupon within a container closure between the liner and the sealant sheet.
