Mechanical principle of vacuum laminating machine
Application principle of vacuum laminating machine:
(1) protect the paper by covering the film. After covering film, it can extend the service life of the cover (or printed surface), especially for the students' textbooks. Therefore, the dosage is increasing. (2) prints are not easily destroyed. The utility model can increase the color effect and the protection function to the color printed picture without being worn after being coated with the film. This is good for the press in the art of printing on the surface of the cover or make a variety of art and design according to the demand, therefore also contributed to the increase of the amount of.
(3) that is, the production of coating film is large. Film coating, that is, the cost of making film is low, easy to start and earn money, enterprises can benefit.

The above three points make the coating "hot", but the quality problems of the coating and the impact on the quality of binding, but few people pay attention to, and the following will be further analyzed.
The main problems existing in the cover and sheet after coating are covered with film:
Surface blistering, wrinkle, bending, uneven shedding separation, not easy to store, these quality problems unresolved for many years, its reason is in many aspects, such as:
1. different kinds of paper.
Effect of 2 different color.
3., the different impacts of climate.
4. environmental and environmental impact.
5., the lack of scientific management of enterprises.
6., the quality of personnel.
