Principle of use of laminating machine:

(1) The paper can be protected by using the instant coating film as the cover. After laminating, the service life of the cover (or the surface of the printed matter) can be prolonged, especially for students’ textbooks, so the dosage 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, and therefore 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 start, and profitable, and the enterprise can make a 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 impact on the quality of binding, which will be further analyzed below.

The main problems of the cover and pages after being coated with the coating film are:

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

1. The influence of different types of paper.

2. The influence of different ink colors.

3. Different influences of climate.

4. The influence of environment and conditions.

5. The enterprise lacks the influence of scientific management.

6. The influence of personnel quality.
