The laminating machine refers to the transparent plastic film is applied to the surface of the printed product by hot pressing, forming a 10-20um film, which protects the printed product and increases the gloss of the printed product. The laminating process is widely used for surface binding and protection of book covers, picture albums, commemorative albums, postcards, product manuals, calendars and maps.
        The laminating process is mainly divided into semi-automatic laminating machine and fully automatic laminating machine. Although the specific operations of semi-automatic and full-automatic are somewhat different, the principle is the same: the adhesive is applied to the plastic film by a roller coating device, heated by a hot-pressing roller, the film is softened, and then the bottom is coated The printed material and the film are pressed together to form a paper-plastic integrated film product.

        According to the different raw materials and equipment used, the film coating process can be divided into coating film process and pre-coating film process. Instant coating refers to the process of using plastic film as the raw material during the laminating operation, firstly coating the adhesive on it, and after drying treatment, then hot-pressing the plastic film and the printed product. The pre-coating type refers to a process method in which a plastic film coated with an adhesive in advance and dried is used as a raw material, and is directly subjected to hot-press compounding with a printed product.
