A second hot-melt film layer 10 is provided on the top surface of the back protective layer 11, and the back protective layer 11 and the second leveling layer 9 are heat-pressed and laminated through the second hot-melt film layer 10 for further leveling.

[0020] A first heat-insulating layer 12 is disposed on the bottom surface of the back protective layer 11. In this embodiment, the back protective layer is made of a flame-retardant PET film for back protection. The first heat-insulating layer 12 is made of a magnetron sputtering metal layer to reflect light and heat radiation on the back, reduce temperature rise, and improve the thermal stability and flame-retardant effect of the back.

[0021] In this embodiment, the base film layer 5 is made of PVC film, which has good flame retardant effect, low cost, and is conducive to the construction of the printing layer 4.
