An environment-friendly foamed container closure laminate with embossed tabs is composed of, from top to bottom, a stiff polymer printing layer-the top surface of a half thereof is embossed, the bottom surface is printed; a stiff polymer reinforcement layer-its half bottom surface is embossed and the stiff polymer printing layer laminated with the stiff polymer reinforcement layer is used as a tab (if no printing is necessary, the stiff polymer printing layer and the stiff polymer reinforcement layer are combined to be a tab layer); a soft polymer foam layer-used as a sealing gasket; a high melting point polymer isolation layer-to insulate the heat transfer from the electromagnetic induction heated metal layer to the soft polymer foam layer; an electromagnetic induction heatable metal layer; and a peelable thermosensitive adhesive layer.
