[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a printable reflective lettering film, comprising a carrier layer 1, a photosensitive adhesive layer 2 disposed on one side of the carrier layer 1, a microbead layer 3 disposed on one side of the photosensitive adhesive layer 2, a reflective layer 4 disposed on one side of the microbead layer 3, an adhesive layer 5 fixedly connected to one side of the carrier layer 1, a release layer 6 disposed on one side of the adhesive layer 5, a protective layer 7 fixedly connected to the outer side of the carrier layer 1, and a waterproof layer 8 fixedly connected to one side of the reflective layer 4. The protective layer 7 can protect the rest during transportation, and the waterproof layer 8 improves the waterproof performance of the reflective lettering film, prevents water penetration, and protects the underlying structure.

[0024] In this invention, preferably, the carrier layer 1 is made of polyethylene or polypropylene and has a thickness of 50-150 micrometers. The carrier layer 1 serves as the supporting structure for the entire reflective lettering film, providing strength and stability. It is a basic layer on which other functional layers are attached.

[0025] In this invention, preferably, the photosensitive adhesive layer 2 is made of photosensitive resin and has a thickness of 20-50 micrometers. The photosensitive adhesive layer 2 is used to receive the ink pattern printed on it. Before curing, the photosensitive adhesive layer 2 can absorb ink. After curing by UV light, it forms a solid pattern layer, which fixes the ink and provides the durability of the pattern.

[0026] In this invention, preferably, the microsphere layer 3 is composed of glass microspheres with a diameter of 50-300 micrometers and a thickness of 50-100 micrometers. The glass microspheres in the microsphere layer 3 can reflect light back to the direction of the light source, which can improve visibility and recognition even at night or in low light conditions. This is the core characteristic of the reflective film.

[0027] In this invention, preferably, the reflective layer 4 covers the microsphere layer 3 and is an aluminum foil or a vacuum-plated aluminum layer. The aluminum foil layer has a thickness of 20-30 micrometers, and the vacuum-plated aluminum layer has a thickness of 5-10 nanometers. The reflective layer 4 enhances the reflective effect of the microsphere layer 3. The reflective layer 4 is usually made of a highly reflective material, which can reflect more light, thereby improving the brightness of the reflective film.

[0028] In this invention, preferably, the adhesive layer 5 is a pressure-sensitive adhesive with a thickness of 20-50 micrometers. The adhesive layer 5 has a microporous structure inside. The adhesive layer 5 ensures that the reflective lettering film can be firmly adhered to various substrates, such as metal, plastic, and glass. The adhesive layer 5 needs to have sufficient adhesion and durability to adapt to different environments and application conditions. At the same time, the microporous structure creates micropores in the adhesive layer to improve air permeability, reduce air bubbles, and make the adhesion more uniform.

[0029] In this invention, preferably, the release layer 6 is silicone-treated paper with a thickness of 50-100 micrometers. During manufacturing, storage and transportation, the release layer 6 protects the adhesive layer 5 from contamination and damage. In use, the release layer 6 is easy for the user to peel off, exposing the adhesive layer, thereby allowing the reflective lettering film to be pasted onto the target surface.

[0030] The working principle and usage process of this utility model are as follows: In use, the carrier layer 1 serves as the supporting structure for the entire reflective lettering film, providing strength and stability. It is a base layer on which other functional layers are attached. The photosensitive adhesive layer 2 is used to receive the ink pattern printed on it. Before curing, the photosensitive adhesive layer 2 can absorb ink. After curing by UV light, it forms a solid pattern layer, fixing the ink and providing the durability of the pattern. The glass microspheres in the microsphere layer 3 can reflect light back to the direction of the light source, improving visibility and recognition even at night or in low light conditions. This is the core characteristic of the reflective film. The reflective layer 4 enhances the reflective effect of the microsphere layer 3. The adhesive layer 5 needs to have sufficient adhesion and durability to adapt to different environments and application conditions. At the same time, the microporous structure creates micropores in the adhesive layer to improve air permeability, reduce air bubbles, and make the adhesion more uniform. The release layer 6 protects the adhesive layer 5 from contamination and damage during manufacturing, storage, and transportation. In use, the release layer 6 is easy for the user to peel off, exposing the adhesive layer, thereby pasting the reflective lettering film onto the target surface.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
