The film coating is a process in which a plastic film is coated with a binder, and the paper printed product is heated and pressurized to bond it together to form a paper-plastic composite product. The film-coated printed product has a thin and transparent plastic film on the surface, and the surface is smoother and brighter, thereby improving the gloss and fastness of the printed product. The color of the graphic is more vivid, three-dimensional, and waterproof. Anti-fouling, abrasion resistance, folding resistance, chemical corrosion resistance, etc.[ Automatic Lamination Machine ]
Air bubbles caused by production processes. Mainly refers to the control of some process parameters, including composite pressure, coating temperature and composite temperature. If the composite pressure is too low, the rubber roller pressure should be increased appropriately.[ Lamination Machine Manufacturer ] The compounding speed is too fast, and the compounding speed can be appropriately lowered, or the temperature of the rubberizing roller can be increased to increase the fluidity of the adhesive. Air bubbles on the surface of the film caused by dust and impurities should improve the environmental sanitation of the production workshop.
