Plastic net teaches you how to use laminating machine
The laminating method is to apply the adhesive to the plastic film, press it together with the printing paper with the paper as the substrate, and press it together with the rubber roller and the heating roller to form a paper-plastic product. The laminated film has a thin and transparent plastic film on the surface, which makes the surface smoother and brighter, which not only improves the gloss and fastness of the printed matter, but also prolongs the service life of the printed matter. At the same time, the plastic film is waterproof. Protection against dirt, abrasion, folding and chemical corrosion. If the transparent bright film is used, the printed image of the laminated product is more vivid and full of three-dimensional, which is especially suitable for the packaging of green foods and the like, which can cause people's appetite and desire for consumption. If a matte film is used, the laminating product will give consumers a noble and elegant feeling. Therefore, the packaged printed matter after lamination can significantly improve the grade and added value of the package. Let's take a look at the use of the laminating machine , as follows:
The laminating machine laminating film is divided into two categories according to equipment and process. One is “coating film†and the other is “pre-coating filmâ€; among them, there are two kinds of film and sub-film.
That is, the coating film is a process of performing paper-plastic compounding by using an instant coating laminating machine with a coating film immediately. It is mainly used as a coating film processing factory or a processing workshop. After applying the adhesive to the reel plastic film as needed, it is dried (slightly) composited and pressurized to adhere the paper film together to form a laminating product. That is, the coating film equipment has two kinds of automatic and semi-automatic, and its basic working principle is the same; the main process flow includes unwinding → gluing coating → drying → compounding → slitting → finished product stacking.
