Abstract: An encapsulation structure for a container comprising a sealing layer, having a plastic layer, an aluminum layer and a heat-sealing adhesive layer, wherein the plastic layer is disposed on the aluminum layer and the aluminum layer is sealed on the rim of the container by the heat-sealing adhesive layer; a strippable foamed-plastic layer engaged in the cap of the container; and a strippable adhesive layer by which the strippable foamed-plastic layer may be adhered to the plastic layer; wherein, after heating the cap, the strippable foamed-plastic layer, the strippable adhesive layer, the sealing layer and the container by electromagnetic induction, the adhesion force of the strippable adhesive layer is smaller than that of the heat-sealing adhesive layer; and, when the cap is opened, the strippable foamed-plastic layer will be detached from the sealing layer along with the cap.

Abstract: An encapsulation structure for a container comprising a sealing layer, having an aluminum layer and a heat-sealing adhesive layer, wherein the aluminum layer is sealed on a rim of the container by the heat-sealing adhesive layer; a strippable foamed-plastic layer deposited in a cap of the container; and a strippable adhesive layer, wherein the strippable foamed-plastic layer is adhered to the aluminum layer by the strippable adhesive layer, and the adhesion force of the strippable adhesive layer is smaller than that of the heat-sealing adhesive layer. Therefore, the encapsulation structure for a container may be environmentally friendly, reduce used materials, be partially recyclable, and securely seal the container.

Abstract: A sealing film with a hidden tab includes a bottom layer and a top layer. The bottom layer includes a heat sealing layer, an aluminum foil layer, and a polypropylene layer. The top layer includes a nylon layer and a polyethylene terephthalate layer, and is defined with a connection portion and a tab portion. The nylon layer in the connection portion is adhered to the polypropylene layer by an adhesive. At least a contact is disposed between the nylon layer in the tab portion and the polypropylene layer. Due to physical properties of the material of which the nylon layer in the tab portion is made, the sealing film is likely to sever but easy to peel off. The contact not only prevents the tab portion of the top layer from warping but also enables a user to determine whether the sealing film has ever been used before.
