Description

Technical Field

[0001] The present invention relates to the technical field of reflective materials, and particularly to a reflective film. Background Art

[0002] Reflective materials can provide the effect of reflecting light, and are usually used in daily items such as lamp shades, clothing reflective strips, traffic signs, etc.

[0003] The hot stamping process is a special printing process without using ink. The so-called hot stamping refers to the process of hot stamping an aluminum foil onto the surface of a printing substrate under certain temperature and pressure. The hot stamping machine is the equipment for completing the hot stamping process.

[0004] Hot stamping can greatly beautify products. Due to the limitations of the conditions of reflective materials themselves, conventional reflective materials cannot be applied to the hot stamping process. Therefore, the applicant has made improvements to the reflective material process to prepare a reflective material that can be applied to the hot stamping process. Summary of the Invention

[0016] In the above technical solution, preferably, the thickness range of the first adhesive layer is 0.5 - 1.5 filaments.

[0017] In the above technical solution, preferably, the thickness range of the second adhesive layer is 0.2 - 1.2 filaments.

[0018] In the above technical solution, preferably, the base layer is a PET film.

[0020] In the above technical solution, preferably, the diameter range of the glass microspheres is 10 - 100 μm.
