1. Cold mounting: The method of mounting the protective film on the surface of the image by cold pressing at normal temperature is called cold mounting, and there are single-sided mounting and double-sided mounting in between. There are also manual peeling and self-releasing films in the operating method Framed. The cold mounting technique has the characteristics of simple operation, good effect and low cost. It is widely used in the post-production of advertising light boxes, engineering drawings and wedding photography.

        2. Hot laminating by laminating machine: The method of mounting the dedicated hot film on the equipment heated to a certain temperature (about 100-180°C) is called hot laminating, which can be divided into single-sided hot lamination and double-sided hot lamination. Because of its good light permeability and water resistance, and strong hardness, it is suitable for the post-production of advertising images in other occasions. However, hot laminating equipment and consumables are more expensive, with messy operations, high energy consumption, and high costs. The vacuum laminating of the automatic laminating machine is to use a special vacuum laminating machine to evacuate the film and the painting and set it at a certain temperature to complete the laminating. Its operation method is messy, the cost is large and the picture scale is bound Limited, but the mounting quality is very high, the picture texture is strong, suitable for photos.
