There are many factors involved in the process of the automatic laminating machine. It is necessary to understand the influence of each process parameter on the quality of the laminating film, and correctly handle the relationship between them to achieve the best effect. The technical parameters and precautions involved in the laminating process of the automatic laminating machine are as follows:
1. Drying temperature-controlled between 50 ~ 70 ℃, can fully evaporate the solvent, and will not cause the film to overheat and deform;
2. Compound temperature-the temperature of the imprint cylinder is controlled at 70 ~ 90 ℃, which can melt the adhesive and the film will not be deformed by overheating;
3. Compound pressure-to ensure that the axial pressure of the impression cylinder is consistent, the pressure should be kept within 150 ~ 250 kg/cm2;
4. Adhesive coating-the coating should be thin, controlled at 3 to 8 g/cm2, and the thickness should be 5 to 8 μm, to avoid excessive coating;
5. Machine speed-a single sheet of paper should be controlled at 35 to 45 sheets/minute, and a roll of paper should be at 3 to 10 meters/minute, in addition to other parameters;
6. Film tension-the tension is adjusted to the minimum to achieve the correct coating and compounding, to avoid excessive tension;
7. Accuracy of the cylinder-The impression cylinder requires a smooth and clean surface without scratches or pits. It is necessary to ensure mechanical accuracy indicators such as ellipticity and concentricity;
8. Environmental factors-to keep the environment clean, air purification devices are required. Control workshop temperature and humidity to prevent deformation of paper or film;
9. Ink thickness——Deep ink and light printing, to avoid the surface tension drop caused by too thick ink layer and make the laminating film not firm;
10. Ink drying-the ink should be dried thoroughly to avoid blistering;

11. Ink additives-the amount of desiccant should be controlled to prevent the ink layer from crystallizing. The film surface of the crystallized ink of the automatic laminating machine will have a laminating phenomenon.
