PROBLEM TO BE SOLVED: To develop no burn on a sheet even when a lit tobacco is left as it lights and allow to easily remove a tar adhered onto the sheet by a structure wherein a fluoroplastic-based film, a design layer, a metal layer, a pressure sensitive adhesive layer and a releasing paper are laminated to one another in the order named. SOLUTION: A fluoroplastic-based film 1, a design layer 3, a metal layer 5, a pressure sensitive adhesive layer 6 and a releasing paper are laminated to one another in the order named. The preferable thickness of the fluoroplastic- based film 1 is 4-100μm. A pressure sensitive adhesive, heat-sensitive adhesive, laminating adhesive or the like can be used between the film 1 and the design layer 3 and between the design layer 3 and the metal layer 5. Especially preferable metal layer 5 is aluminum and copper due to their large heat conductivities and to their easy procurement in the form of foil. Further, the preferable thickness of the pressure sensitive adhesive layer 6 is normally 10-100μm. Thus, since contamination is hard to infiltrate in the fluoroplastic-based film, the adhered tar of tobacco can easily be wiped off. |
