[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] A foam lettering film, such as Figure 1-Figure 3 As shown, it includes a weather-resistant layer 1, a refractive layer 2, a font foaming layer 3, a framework layer 4, a base layer 5 and a glue layer 6 which are stacked in sequence. The framework layer 4 is hollow and is provided with a side foaming layer 7. The side foaming layer 7 is arranged in the framework layer 4. During the thermal transfer process of the lettering film, the font foaming layer 3 and the side foaming layer 7 are heated and expanded. The side foaming layer 7 expands toward the cut edge under the restriction of the framework layer 4 to form a frame around the font foaming layer 3, so that the user can directly cut the lettering film during the production process. The lettering film is adhered by the glue layer 6, and the glue layer 6 is set as a hot melt adhesive film. During the thermal transfer process of the lettering film, the lettering film as a whole is adhered by the hot melt adhesive film. Adhere to the carrier to form its fixation on the carrier, the font foam layer 3 and the side foam layer 7 can be fixed to each other after expansion, and after hot pressing, the font foam layer 3 and the side foam layer 7 will both expand, the framework layer 4 is set to two layers, and a plurality of connecting strips 8 are arranged between the two layers of the framework layer 4 to form a hollow structure, and the connecting strips 8 are used to limit the maximum interval between the two layers of the framework to prevent the two layers of the framework layer 4 from being unable to form an edge wrapping effect on the font foam layer 3 due to the expansion of the side foam layer 7, and the connecting strips 8 are arranged in an arranged manner, and the arranged connecting strips 8 can make the tension on the two layers of the framework layer 4 close to the average state, so as to maintain the connection state between the two layers of the framework layer 4.

[0021] The structure layer 4 is provided with a plurality of openings 9 in the area near the font foaming layer 3. The side foaming layer 7 can penetrate the openings 9 and form adhesion with the font foaming layer 3. The setting of the side openings 9 enables the materials between the side foaming layer 7 and the font foaming layer 3 to press against each other during the foaming process and form mutual connection, thereby forming a mutual adhesion effect and enhancing the firmness between the layers of the lettering film. The refractive layer 2 is provided with a structure in which the structural layer 10 and the refractive beads 11 are nested with each other. The refractive layer 2 is provided with a mesh-like structure, which is used to fix the position of the refractive beads 11 and refract light through its structure. The cross-section of the structural layer 10 between the two cavities is formed into a hexagonal structure, and the structural layer 10 is formed with a plurality of cavities for the refractive beads 11 to be embedded. The setting of the hexagonal structure is used to refract the light source by the refractive layer 2 when the external ambient light irradiates and enters the refractive layer 2. In addition, the shape formed by the glass beads achieves the effect of focusing light and local brightening, so that the overall lettering film is more conspicuous when the ambient light brightness is insufficient.

[0022] The structural layer 10 is made of a resin material, which has the characteristics of being light, not easy to break, having good light transmittance, and having low production cost, and is easy to produce and use.
