[0025] The overall polyester film layer 1 and the overall first high-temperature-resistant layer 2 are adhesively connected, the overall first high-temperature-resistant layer 2 and the breathable layer 3 are adhesively connected, the second high-temperature-resistant main strip 201 and the second high-temperature-resistant secondary strip 202 are alternately connected in the first high-temperature-resistant layer 2, the overall first high-temperature-resistant layer 2 is made of aluminum material, the surface of the breathable layer 3 is provided with the breathable hole 4, and then the air outside enters between the first high-temperature-resistant layer 2 and the breathable layer 3 through the breathable hole 4, so that the surface of the second high-temperature-resistant main strip 201 and the second high-temperature-resistant secondary strip 202 contacts and oxidizes with the oxygen in the air, the aluminum reacts with the oxygen to generate aluminum oxide, and the aluminum oxide is a high-temperature-resistant material, which improves the high-temperature-resistant performance of the overall ironing picture film.

[0026] The second high-temperature-resistant main strip 201 is arranged with a plurality of insertion parts 203 on both sides, and the second high-temperature-resistant secondary strip 202 is arranged with a plurality of groove parts 204 on both sides. The arrangement increases the contact area between the second high-temperature-resistant main strip 201 and the second high-temperature-resistant secondary strip 202 and the oxygen in the air, thereby increasing the volume of oxygen that penetrates into the air-permeable layer 3, and further increasing the oxidation of more aluminum on the surface of the second high-temperature-resistant main strip 201 and the second high-temperature-resistant secondary strip 202 into aluminum oxide, thereby further improving the high-temperature resistance of the first high-temperature-resistant layer 2.
