Classification of laminating methods for automatic laminating machines.

 The automatic laminating machine can be divided into two categories: instant-coating laminating machine and pre-coating laminating machine. It is a kind of special equipment for paper and film. The following briefly introduces the laminating method of the laminating machine.

The laminating process completed with various materials and equipment is divided into several categories according to the temperature and purpose of the raw materials (consumables) used.

Cold laminating machine: The method of laminating the protective film on the surface of the picture by cold pressing at room temperature is called cold laminating. Among them, there are single-sided mounting and double-sided mounting. In the operation method, there are also manual peeling and self-removing film mounting. The cold lamination process 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.

Thermal laminating machine: The mounting method of dedicated thermal film on equipment heated to a certain temperature (about 100-180°C) is called thermal mounting, which can be divided into single-sided thermal mounting and double-sided thermal mounting. It has good light transmittance and water resistance, good heat resistance, and strong hardness. It is suitable for post-production of advertising pictures relying on lighting or other occasions. However, heat lamination equipment and consumables are more expensive, complicated to operate, high energy consumption, and high cost.

Plastic laminating machine: similar to thermal laminating, but generally miniaturized. The largest plastic packaging equipment on the market is 24 inches. It is packaged by special plastic film heating and is mainly used for packaging documents, small-size pictures or documents.
