The gluing of simulated plants is to add a thin and transparent plastic film on the surface of simulated plants during the production process, which is more complicated than the gluing process of printed matter. After gluing, the surface of the simulated plant is smoother and brighter, thus improving the gloss and fastness of the simulated plant. After gluing, it can protect the simulated plants and make them have the functions of friction resistance, moisture resistance, light resistance, waterproof, pollution prevention and chemical corrosion resistance.
