1. The drying temperature is controlled between 50-70℃, which can fully evaporate the solvent without causing the film to overheat and deform;
2. Compound temperature The temperature of the impression cylinder is controlled at 70-90℃, which can melt the adhesive and the film will not be deformed by overheating;
3. Compound pressure Ensure that the axial pressure of the impression cylinder is consistent, and the pressure should be kept within 150-250kg/cm2;
4. Adhesive coating The coating should be thin, controlled at 3-8g/cm2, and the thickness is 5-8μm, to avoid excessive coating;
5. Machine speed: The single sheet of paper should be controlled at 35-45 sheets/minute, and the roll paper should be at 3-10 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. Cylinder accuracy The impression cylinder requires a smooth and clean surface with no 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 should be 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 Ink drying should be thorough to avoid blistering;

11. Ink additives To control the amount of desiccant added to prevent the ink layer from crystallizing. The surface of the crystallized ink will have a loose film.
