The adhesion fastness of laminated products depends on the adhesion between the film, printed matter and adhesive. This is the result of the diffusion and penetration of adhesive molecules on the surface of films and prints. Temperature and pressure are important conditions for good diffusion and penetration. The adhesive force of the adhesive directly affects the quality of the film-coated product, and the adhesive force mainly shows the mechanical and physical and chemical bonding between the adhesive and the adherend. The coating usually uses solvent-based adhesives, water-soluble adhesives and hot-melt adhesives. Before hot pressing, the adhesive coating device uniformly coats the glue on the surface of the plastic film, and the plastic film and the printed matter are hot-pressed and compounded by the compounding device, and finally a paper-plastic product is obtained. The printed matter after laminating treatment will be brighter and more colorful, which obviously improves the artistic grade and value of the printed matter, plays a protective role, and protects the printed matter from water, light, friction and pollution, and does not change the graphic information and color of the printed matter. show.
