The laminating machine refers to the transparent plastic film is pasted on the surface of the printed matter by hot pressing to form a 10-20um film, which protects the printed matter and increases the gloss of the printed matter. It is also known as laminating. The laminating process is widely used for surface binding and protection of book covers, picture albums, commemorative albums, postcards, product manuals, calendars and maps.
        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, applying adhesive on it, drying it, and then hot-pressing the plastic film and the printed product. The pre-coating type refers to a process method in which a plastic film pre-coated with an adhesive and dried is used as a raw material, and is directly subjected to hot-press lamination with printed products.

        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, and the film is softened by the heat and pressure roller, and then the bottom is coated The printed material and the film are pressed together to form a paper-plastic integrated film product.
