Description

Technical Field

[0001] The utility model relates to the technical field of laminated paper production, in particular to a laminated material extrusion device for laminated paper production. Background Art

[0002] Laminated paper is a special paper used for laminating process, also known as laminated base paper or coated substrate. In the printing and packaging industry, laminated paper is often used in the production of packaging materials to provide additional protection and decorative effects. Laminated paper usually has a very smooth surface and is suitable for various surface treatments such as coating, hot stamping, gravure, etc. to enhance the visual effect of the packaged products. Due to the special production process of laminated paper, it has strong wear resistance, which can effectively protect the packaged items and extend their service life. Laminated paper usually has good moisture resistance, which can effectively prevent the packaged items from getting damp and maintain the quality and integrity of the product. Laminated paper is suitable for various printing processes, which can achieve colorful packaging design effects and enhance the market competitiveness of products. Laminated paper is often used in the packaging industry to make various types of packaging boxes, bags, bagged foods, etc. Laminated paper can enhance the waterproofness, wear resistance and tear resistance of paper, and also improve the appearance texture of the packaged products.

[0003] After the existing laminated paper is made into a packaging box, it will be damaged and the corners will be warped after being used many times. The damage and warping of the laminated paper will reduce its protective effect on the paper, making the paper more susceptible to moisture, pollution and physical damage, thereby shortening the service life of the paper. For some laminated papers with special purposes, such as waterproof stickers or tabletop game cards, damage and warping will directly affect their functions and reduce the practicality and reliability of the product. Damaged laminated paper may cause the paper surface to easily absorb dust, bacteria, etc., which is not conducive to the hygiene and cleanliness of the product, especially in related fields such as food packaging. Therefore, in order to increase the service life of laminated paper, a laminated material extrusion device for laminated paper production is proposed. Utility Model Content
