With various materials, the laminating process completed by the small laminating machine is divided into several categories according to the temperature and use of the raw materials (consumables) used, and the following categories are introduced.
Cold laminating: 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 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. At present, it is widely used in the post-production of advertising light boxes, engineering drawings and wedding photography.
Principle of use of small laminating machine:
(1) Use instant coating film as cover to protect paper. After laminating, the service life of the cover (or the surface of the printed product) can be prolonged, especially for students' textbooks, so the amount is increasing.
(2) The impression is not easy to be destroyed. After being coated with a coating film, it can increase the color effect and protect the color printing graphics and texts without causing them to be worn. This is conducive to publishing houses' art editors to make various art designs on the surface of the cover or printed matter according to their needs, which also promotes the increase in usage.

(3) The production of coating film is profitable. In the coating process, the production cost of the coating film is low, easy to use, and profitable, and the enterprise can profit.
