During the production and use of the domestic equipment automatic laminating machine, poor temperature control will cause the degradation and cross-linking of the high-molecular polymer in the hot-melt adhesive, making the laminating surface bad. Some pre-coated film colloids are easy to adhere to the surface of the substrate, resulting in poor winding; some thin surfaces of the adhesive layer are not activated, which is prone to defects such as insufficient adhesion to the printed matter; because the hot melt adhesive is made of a mixture of several materials , The transparency after coating is obviously worse than the low temperature pure resin pre-coating film.
        The water content in the paper is too large, the paper shrinks after the film is dried, and the film is deformed and wrinkled;
        Solution "The moisture content of the paper should be about 5% to keep the temperature and humidity in the working room normal.
        The laminating machine's conduction roller is not running well or there are dirt on the surface, which prevents the film from stretching and running normally;

        Solution: Conductor roller bearings should be lubricated on time and kept clean and free of foreign objects.
