AI Technical Summary
In existing laminating devices, air bubbles generated by the laminating paper are difficult to remove effectively during the laminating process, affecting the laminating effect.
By installing the laminating components on the cover, combined with heating and cooling rollers, and using pressure rollers and extrusion blocks, the laminated paper is repeatedly pressed to reduce the generation of air bubbles.
It improves the adhesion of the coating, reduces the formation of air bubbles, and enhances the coating effect.
