Principle Of Use Of Laminating Machine

Mechanical principle

(1) Use instant coating film as cover to protect paper. After laminating, the service life of the cover (or the surface of the printed matter) 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 covers or prints 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.

The above three points make the coating film "hot", but few people pay attention to the quality problems of the coating film and the influence on the quality of binding, which will be further analyzed below.

The main problems of the covers and sheets after being coated with film are:

Surface blistering, wrinkles, uneven bending, shedding and separation, and difficult storage. These quality problems have not been solved for many years, and the reasons are also various, such as:

1. The influence of different paper types.

2. The influence of different ink colors.

3. Different effects of climate.

4. The influence of environment and conditions.

5. The enterprise lacks the influence of scientific management.

6. The influence of personnel quality.
