The coating process completed by various materials and equipment can be divided into several categories according to the temperature and use of raw materials (consumables). The following categories are introduced.
Cold mounting: The method of mounting the protective film on the surface of the picture by cold pressing at normal temperature is called cold mounting.There are also one-sided and two-sided mounts.There are also manual and self-uncovering film mounting methods in operation.Cold mounting process is characterized by simple operation, good effect and low cost.It is widely used in post-production of advertising light boxes, engineering drawings and wedding photography.

Heat Mounting

    The mounting method of special hot film on equipment heated to a certain temperature (about 100-180 degrees C) is called hot mounting, which can be divided into one-sided hot mounting and two-sided hot mounting. Because of its good light transmittance and water resistance, good heat resistance and strong hardness, it is suitable for later production of advertising pictures relying on lighting or in other occasions.However, the price of hot-mounting equipment and consumables is expensive, the operation is complicated, the energy consumption is high and the cost is high.
    Similar to hot mounting, but generally smaller.The largest plastic encapsulation equipment on the market is 24 inches, which is encapsulated by special plastic film heating. It is mainly used for encapsulation of certificates, small size pictures or documents.
