There are three methods for laminating. One is to coat the adhesive on the surface of the plastic film and bond it with the substrate (printed matter) through a pressing roller, and then dry or roll it directly without drying, which is called wet laminating; the other is One is to coat the adhesive on the plastic film, after drying to remove the adhesive solvent, and then bond with the substrate, called dry film; the third is the pre-coating film, the adhesive is applied It is clothed on the surface of the plastic film and dried for later use. When necessary, the pre-coated film and the substrate are bonded together. 1. Wet-type laminating: Wet-type laminating requires the installation of adhesive coating equipment on the laminating equipment. The adhesive is applied first, then the film is bonded to the substrate, and finally dried to complete the laminating work at one time. The wet coating process is simple to operate, less adhesive, low cost, fast coating speed, no solvent volatilization, and is beneficial to environmental protection. The surface of the coated product is not easy to foam and wrinkle. 2. Dry-type film Dry-type film is dried first and then bonded. Adhesive coating, drying, hot pressing and rewinding and cutting are completed on the same machine. The dry laminating process is simple to operate, with less adhesive consumption, low cost, fast laminating speed, and good laminating quality; but the solvent volatilizes and pollutes the environment. 3. Pre-coating film coating The pre-coating film coating is to coat the adhesive on the plastic film, after drying and rewinding, it is ready for use, and the coating is completed by hot pressing on the laminating equipment without the adhesive coating device Work, laminating equipment does not require adhesive coating and drying devices. The pre-coating film is easy to operate, flexible in production, has no solvent odor, does not pollute the environment, and has good working conditions. This coating method will not produce bubbles, delamination and other failures, and has high surface transparency, which has great application prospects and promotion value. Summary Laminating is one of the surface treatment technologies of printed materials. Now it is widely used in the surface treatment of books and magazines, packaging boxes, especially the surface of high-end packaging boxes, exquisite picture albums, wall calendars, desk calendars, printed propaganda materials, various manuals and various Kinds of surface decoration and surface decoration treatment of various paper packaging products. Laminating technology is widely used because of its low cost. It has an obvious effect on improving the brightness of printed matter and improving the durability of printed matter, and has good development prospects. In particular, the pre-coating film coating technology has more application prospects and promotion value.
