The present disclosure is capable of enhancing an anti-counterfeiting ability of a product when used.

Abstract: A roll material comprises an adhesive sealing film, and a lifting and pulling composite layer, located on the adhesive sealing film. The lifting and pulling composite layer includes an information layer, a backing layer, and a layer of functional film sequentially from top to bottom. The layer of functional film has a PE film or an EPE film and a plurality of microbonding blocks sequentially from top to bottom, and the plurality of microbonding blocks is coated with a release coating. The roll material can be made into an anti-counterfeiting sealing film, which has a good re-sealing effect and anti-counterfeiting effect.

Abstract: An anti-counterfeiting electromagnetic induction sealing liner includes, from top to bottom order, a composite function layer, an electromagnetic induction heating layer, and an adhesion layer combined together. The composite function layer includes, from top to bottom order, an information layer and a support layer combined together. The information layer has therein an information chip and an antenna circuit electrically connected to the information chip. The composite function layer has a structurally weak region. The structurally weak region crosses the antenna circuit. The anti-counterfeiting electromagnetic induction sealing liner seals a container mouth and has an information read/write function. Therefore, the information layer is destroyed the first time the container mouth is opened, thereby improving the anti-counterfeiting function.

Abstract: A multifunction electromagnetic induction sealing liner includes, from top to bottom order, a composite function layer, an electromagnetic induction heating layer, and an adhesion layer combined together. The composite function layer includes, from top to bottom order, an information layer and a backing layer combined together. The information layer has therein an information chip and an antenna circuit electrically connected to the information chip. The composite function layer includes a grip portion, a primary cutting line and a secondary cutting line. The primary cutting line runs annularly and divides the composite function layer into an outer ring and an inner ring. The grip portion is disposed inside the inner ring and connected thereto. The secondary cutting line is disposed in the inner ring and connected to a lateral edge of the grip portion. The antenna circuit crosses the primary cutting line and/or the secondary cutting line.

Abstract: A radio frequency identification gasket for sealing a bottle mouth has an adhesive layer, an aluminum-plastic film layer, a radio frequency identification layer and a composite film functional layer from bottom to top, wherein the composite film functional layer is formed with a reserved structural weakening zone therein, the radio frequency identification layer is set with a structure of a radio frequency identification antenna line that is destroyed when the composite film functional layer is torn. The composite film functional layer forms the reserved structural weakening zone therein through physical treatment, and the physical treatment is one of die micro-pressing, laser micro-cutting or electron beam micro-cutting. The radio frequency identification gasket is mounted in the bottle mouth and has the functions of sealing and reading and writing radio frequency tags, and also has an anti-counterfeiting effect.

Abstract: A ring-peel-seal liner is revealed, the ring-peel-seal liner includes a metal sealing layer and an adhesive layer. The metal sealing layer has a first annular tear line, and is defined into an annular region and a central region by the first annular tear line, wherein the annular region encircles the central region. The adhesive layer is adhered on one surface of the metal sealing layer. With the ring-peel-seal liner described above, the issue of needing an additional liner for enhancing a sealing effect after opening a conventional packaging container is resolved.

Abstract: A container seal includes an inner element and an outer element. The inner element has at least one through hole. The outer element is adhered to the inner element and is releasable from the inner element. The container seal is conducive to preventing a user from being stained with contents of a container covered with the container seal while tearing the container seal. The container seal can be pierced by a soft straw whereby the user sucks the contents of the container.
