[0002] Laminated paper is a composite material made by coating plastic particles onto the surface of paper using a casting machine. Its key features are oil-proof (relatively), water-proof (relatively), and heat-sealable. Different applications require different properties: for hamburger packaging, oil-proof properties are preferred; for coated paper wrapping, water-resistant properties are preferred; and for automatic packaging, heat-sealability is preferred. During the laminated paper processing process, different patterns need to be printed on the surface depending on its intended use, requiring a printing device. Most existing devices do not effectively flatten the laminated paper before printing and are difficult to clean, impacting the quality of the printed product.
