Various products such as food, medicine, and cosmetics need high-quality packaging to attract consumers. Lamination can make the packaging surface smoother and shinier, improve the wear resistance, water resistance and moisture resistance of the packaging, thereby better protecting the product and extending its shelf life. Therefore, the demand for laminators in the packaging industry is constantly increasing.
[0003] In the printing industry, the demand for lamination is growing to improve the quality and durability of printed materials. Lamination of books, brochures, posters, and other printed materials not only enhances color effects but also prevents ink fading and paper damage, improving the overall quality of the printed materials and meeting the market's demand for high-quality printed products.
[0004] Regarding the existing related technologies, the inventors believe that the following defects exist: After the existing film coating machine has finished coating the material, the internal roller does not have a limiting device, which makes it easy for the film to drive the roller to rotate, resulting in waste.
